Modulatory potential of Bacopa monnieri against aflatoxin B1 induced biochemical, molecular and histological alterations in rats.

Oxidative injury is concerned with the pathogenesis of several liver injuries, including those from acute liver failure to cirrhosis. This study was designed to explore the antioxidant activity of Bacopa monnieri (BM) on Aflatoxin B1 (AFB1) induced oxidative damage in Wistar albino rats. Aflatoxin B1 treatment (200 µg/kg/day, p.o.) for 28 days induced oxidative injury by a significant alteration in serum liver function test marker enzymes (AST, ALT, ALP, LDH, albumin and bilirubin), inflammatory cytokines (IL-6, IL-10 and TNF-α), thiobarbituric acid reactive substances (TBARS) along with reduction of antioxidant enzymes (GSH, SOD, CAT), GSH cycle enzymes and drug-metabolizing enzymes (AH and AND). Treatment of rats with B. monnieri (20, 30 and 40 mg/kg for 5 days, p.o.) after 28 days of AFB1 intoxication significantly restored these parameters near control in a dose-dependent way. Histopathological examination disclosed extensive hepatic injuries, characterized by cellular necrosis, infiltration, congestion and sinusoidal dilatation in the AFB1-treated group. Treatment with B. monnieri significantly reduced these toxic effects resulting from AFB1. B. monnieriper se group (40 mg/kg) did not show any significant change and proved safe. The cytotoxic activity of B. monnieri was also evaluated on HepG2 cells and showed a good percentage of cytotoxic activity. This finding suggests that B. monnieri protects the liver against oxidative damage caused by AFB1, which aids in the evaluation of the traditional usage of this medicinal plant.

Evaluating the effects of Bacopa monnieri on cognitive performance and sleep quality of patients with mild cognitive impairment: A triple-blinded, randomized, placebo-controlled trial.

INTRODUCTION: Mild cognitive impairment is the middle level of natural cognitive impairment during primary steps of dementia. There are a few studies about improving the cognitive performance and sleep quality in patients with a limited dementia. So, this study was conducted to evaluate the effects of Bacopa monnieri on cognitive performance and sleep quality of patients with mild cognitive impairment. MATERIALS AND METHODS: In this study, 62 patients with mild cognitive impairment were categorized into two groups of control and intervention. The intervention group received one pill of 160 mg Bacopa monnieri extract in 2 months, and the control group received a pill containing starch powder. The cognitive impairment and sleep quality was assessed using a questionnaire containing demographic information, Montreal Cognitive Assessment, and the Pittsburg Sleep Quality Index in three time-points of before the study, one months after the intervention and 2 months after the intervention (the end of study). RESULTS: The results showed no statistically significant difference between two groups in all three time-points in overall cognitive performance score and its 6 parameters (P > 0.05). While in the field of attention at the end of the first month (P = 0.033) and the end of the second month (P = 0.004), it was significant difference between the study groups. Also, in the field of verbal fluency at the end of the second month, this difference was significant (P = 0.003). The cognitive performance overall score showed no significant difference between two groups in first (P = 0.939) and second time-points (P = 0.661), although it was significant at third time-point (P = 0.029). There was no statistically significant difference between two groups in all time-points for sleep quality overall score (P > 0.05). CONCLUSION: The results showed that Bacopa monnieri can improve the cognitive performance overall score and some of its parameters, but it had no effect on sleep quality.

Investigating Bacopa monnieri L. Therapeutic Potential for the Treatment of Neurological Diseases.

The popular perennial creeping plant known as Bacopa monnieri (also known as Brahmi) is being utilized in the Indian Ayurvedic medicine practice. It has a variety of bioactive phytoconstituents that have been used therapeutically to treat a number of serious illnesses. Ancient Vedic scholars used this herb because of its pharmacological effects, particularly as a nerve booster and nootropic supporter. However, it is vital to comprehend the active phytochemical components of Bacopa monnieri extract (BME) and their molecular mechanisms in order to better grasp the effect of BME on neurological illnesses and diseases. Understanding its active phytochemical constituents and their molecular processes is essential. Numerous clinical investigations indicated that BME may have neuroprotective benefits, so it is worthwhile to re-evaluate this wellknown plant. Here, we focused on neurological problems as we examined the pharmacological and phytochemical characteristics of BME. For their effective usage in neuroprotection and cognition, many clinical concerns and the synergistic potential of Bacopa extract have been investigated. Alzheimer's disease is a neurological condition caused by the production of reactive oxygen species, which also causes amyloid-beta (Aß) and tau protein aggregation and increases neuro-inflammation and neurotoxicity. Our review offers a more indepth molecular understanding of the neuroprotective functions of BME, which can also be connected to its therapeutic management of neurological illnesses and cognitive-improving effects.

Analyzing the Antihyperglycemic Effect of Cissus quadrangularis and Bacopa monnieri on 3T3-L1 Cell Lines.

Background Cissus quadrangularis is a perennial shrub of the grape family. Other names for it include devil's backbone, veld grape, and pirandai (Tamil). Bacopa monnieri, a perennial plant, is native to wetlands in eastern and southern India. The 3T3-L1 cell line, which was created from 3T3 cells, was used in the scientific study. The current study's purpose is to evaluate the antihyperglycemic benefits of B. monnieri and C. quadrangularis, which will be added to the current arsenal of efficient herbal hypoglycemic medications. Aim To analyze and compare the anti-hyperglycaemic effects of the two plant extracts, C. quadrangularis and B. monnieri using a 3T3-L1 cell line. Materials and methods C. quadrangularis seeds were gathered, and extraction was conducted. The B. monnieri plant was harvested, and a rotary evaporator was used to extract the flower. Adipocyte cells were obtained from NCCS, Pune. A CO2 incubator was used to incubate the cells. The MTT assay and gene expression analysis were done on the cell line samples. Results The antihyperglycemic effects of C. quadrangularis IRS mRNA levels of 0.7 and AKT mRNA levels of 0.7 are compared to B. monnieri IRS1 mRNA levels of 0.6 and AKT mRNA levels of 0.6 to build better diabetic treatments. The antihyperglycemic benefits of C. quadrangularis levels of IRS mRNA and AKT mRNA are compared to the influence of B. monnieri IRS1 mRNA and AKT mRNA on the development of better diabetic drugs. Conclusion Comparing the effects of C. quadrangularis and B. monnieri on the 3T3 cell line by gene expression of IRS mRNA and AKT mRNA suggests that the particular AKT downregulation shows that insulin suppresses gluconeogenesis and C. quadrangularis inhibits hyperglycemia in 3T3-L1 cells, while research on in vitro rats suggests that B. monnieri may minimize the signs and symptoms of diabetes via enhancing IRS1/AKT signaling.

Anticancer activity of Bacopa monnieri through apoptosis induction and mitophagy-dependent NLRP3 inflammasome inhibition in oral squamous cell carcinoma.

BACKGROUND: Bacopa monnieri (BM) is traditionally used in human diseases for its antioxidant, anti-inflammatory and neuroprotective effects. However, its anticancer potential has been poorly understood. AIM: The aim of this study was to explore the detailed anticancer mechanism of BM against oral cancer and to identify the bioactive BM fraction for possible cancer therapeutics. RESULTS: We performed bioactivity-guided fractionation and identified that the aqueous fraction of the ethanolic extract of BM (BM-AF) had a potent anticancer potential in both in vitro and in vivo oral cancer models. BM-AF inhibited cell viability, colony formation, cell migration and induced apoptotic cell death in Cal33 and FaDu cells. BM-AF at low doses promoted mitophagy and BM-AF mediated mitophagy was PARKIN dependent. In addition, BM-AF inhibited arecoline induced reactive oxygen species production in Cal33 cells. Moreover, BM-AF supressed arecoline-induced NLR family pyrin domain containing 3 (NLRP3) inflammasome activation through mitophagy in Cal33 cells. The in vivo antitumor effect of BM-AF was further validated in C57BL/6J mice through a 4-nitroquinolin-1-oxide and arecoline-induced oral cancer model. The tumor incidence was significantly reduced in the BM-AF treated group. Further, data obtained from western blot and immunohistochemistry analysis showed increased expression of apoptotic markers and decreased expression of inflammasome markers in the tongue tissue obtained from BM-AF treated mice in comparison with the non-treated tumor bearing mice. CONCLUSION: In conclusion, BM-AF exhibited potent anticancer activity through apoptosis induction and mitophagy-dependent inhibition of NLRP3 inflammasome activation in both in vitro and in vivo oral cancer models. Moreover, we have investigated apoptosis and mitophagy-inducing compounds from this plant extract having anticancer activity against oral cancer cells.

Bacopa monnieri: A promising herbal approach for neurodegenerative disease treatment supported by in silico and in vitro research.

Neurodegenerative disorders, caused by progressive neuron loss, are a global health issue. Among the various factors implicated in their pathogenesis, dysregulation of acetylcholinesterase activity has been recognized as a key contributor. Acetylcholinesterase breaks down the neurotransmitter acetylcholine, important for neural transmission. Evaluating phyto-compounds from Bacopa monnieri Linn. through in vitro and in silico analysis may expand their role as alternative therapeutic agents by modulating the function of acetylcholinesterase and complementing existing treatments. To accomplish this objective, chemical structures of phyto-compounds were retrieved from PubChem database and subjected to in silico and in vitro approaches. Virtual screening was performed through molecular docking and molecular dynamic simulation resulting in four top hit compounds including quercetin, apigenin, wogonin, and bacopaside X (novel lead compound for acetylcholinesterase inhibitor) with least binding score. Further, dose dependent acetylcholinesterase inhibition biochemical assay depicted that bacopaside X, apigenin, quercetin, and wogonin exhibited strong potential against acetylcholinesterase with IC50 values of 12.78 µM, 13.83 µM, 12.73 µM and 15.48 µM respectively, in comparison with the donepezil (IC50: 0.0204 µM). The in silico and in vitro research suggests that B. monnieri phyto-compounds have the potential to modulate molecular targets associated with neurodegenerative diseases and have a role in neuroprotection.

Comprehensive analysis using DNA metabarcoding, SCAR marker based PCR assay, and HPLC unveils the adulteration in Brahmi herbal products.

BACKGROUND: Brahmi is one of the important nootropic botanicals, widely sold in the market, with the name "Brahmi'' being used to describe both Bacopa monnieri and Centella asiatica species. The Brahmi herbal products market is expanding; hence, economically motivated adulteration is highly prevalent. METHODS AND RESULTS: This study aimed to develop DNA-based methods, including SCAR marker-based PCR and metabarcoding, to authenticate Brahmi herbal products and compare these methods with HPLC. These methods have been validated using mock controls (in-house blended formulations). All targeted plant species in mock controls were detected successfully with all three methods, whereas, in market samples, only 22.2%, 55.6%, and 50.0% were found positive for Brahmi by PCR assay, DNA metabarcoding, and HPLC, respectively. Metabarcoding can detect the presence of non-labeled plants together with targeted species, which is an advantage over PCR assay or HPLC. CONCLUSION: SCAR marker-based PCR is a rapid and cost-effective method for detecting the presence of B. monnieri and C. asiatica. However, in this study, the success rate of PCR amplification was relatively low because the primers targeted either RAPD or ITS-based SCAR markers. HPLC assay, although an alternative, was unable to detect the presence of other botanicals, just like the SCAR marker-based PCR assay. On the other hand, metabarcoding can be utilized to identify the target plants, even in very small quantities, while also providing simulated identification of other botanicals. This study successfully addressed the need for quality control of Brahmi herbal products and provided the first-time report of DNA metabarcoding for such products.

Advanced network pharmacology study reveals multi-pathway and multi-gene regulatory molecular mechanism of Bacopa monnieri in liver cancer based on data mining, molecular modeling, and microarray data analysis.

Liver cancer is a malignant tumor that grows on the surface or inside the liver. The leading cause is a viral infection with hepatitis B or C virus. Natural products and their structural analogues have historically made a major contribution to pharmacotherapy, especially for cancer. A list of studies evidences the therapeutic efficacy of Bacopa monnieri against liver cancer, but the precise molecular mechanism is yet to be discovered. This study combines data mining, network pharmacology, and molecular docking analysis to potentially revolutionize liver cancer treatment by identifying effective phytochemicals. Initially, the information on active constituents of B. monnieri and target genes of both liver cancer and B. monnieri were retrieved from literature as well as from publicly available databases. Based on the matching results between B. monnieri potential targets and liver cancer targets, the protein-protein interaction (PPI) network was constructed using the STRING database and imported into Cytoscape for screening of hub genes based on their degree of connectivity. Later, the interactions network between compounds and overlapping genes was constructed using Cytoscape software to analyze the network pharmacological prospective effects of B. monnieri on liver cancer. Gene Ontology (GO) and KEGG pathway analysis of hub genes revealed that these genes are involved in the cancer-related pathway. Lastly, the expression level of core targets was analyzed using microarray data (GSE39791, GSE76427, GSE22058, GSE87630, and GSE112790). Further, the GEPIA server and PyRx software were used for survival and molecular docking analysis, respectively. In summary, we proposed that quercetin, luteolin, apigenin, catechin, epicatechin, stigmasterol, beta-sitosterol, celastrol, and betulic acid inhibit tumor growth by affecting tumor protein 53 (TP53), interleukin 6 (IL6), RAC-alpha serine/threonine protein kinases 1 (AKT1), caspase-3 (CASP3), tumor necrosis factor (TNF), jun proto-oncogene (JUN), heat shot protein 90 AA1 (HSP90AA1), vascular endothelial growth factor A (VEGFA), epidermal growth factor receptor (EGFR), and SRC proto-oncogene (SRC). Through, microarray data analysis, the expression level of JUN and IL6 were found to be upregulated while the expression level of HSP90AA1 was found to be downregulated. Kaplan-Meier survival analysis indicated that HSP90AA1 and JUN are promising candidate genes that can serve as diagnostic and prognostic biomarkers for liver cancer. Moreover, the molecular docking and molecular dynamic simulation of 60ns well complemented the binding affinity of the compound and revealed strong stability of predicted compounds at the docked site. Calculation of binding free energies using MMPBSA and MMGBSA validated the strong binding affinity between the compound and binding pockets of HSP90AA1 and JUN. Despite that, in vivo and in vitro studies are mandatory to unveil pharmacokinetics and biosafety profiles to completely track the candidature status of B. monnieri in liver cancer.

Antioxidant, Anti-Inflammatory and Anti-Obesity Potential of Extracts Containing Phenols, Chlorophyll and Carotenoids from Mexican Wild Populations of Bacopa monnieri (L.) Wettst.

Some of the species of the genus Bacopa have been used in Pharmacopoeia worldwide. However, in Mexico, Bacopa monnieri has neither been extensively cultivated nor studied, nor has their use in traditional medicine been reported. The aim of this work was to assess the taxonomic verification of the four wild populations of B. monnieri, the chemical content of their pigments and phenols and to provide an analysis of their potential bioactivity. B. monnieri wild populations from Mexico were validated using molecular markers. Chromatographic profiling using HPLC-PDA revealed 21 compounds comprising 12 chlorophylls and nine carotenoids; of the latter, the major ones were lutein (0.921 ± 0.031 µg/mg of dry extract) and ß-carotene (0.095 ± 0.003 µg/mg of dry extract). The total phenolic content, determined using the Folin-Ciocalteu assay, ranged from 54.8 ± 5.8 to 70.3 ± 2.2 µg of gallic acid equivalents (GAE)/mg. Plant extracts scavenged from the free radical DPPH in IC50 ranged from 130.6 ± 3.0 to 249.9 ± 12.1 µg dry extract/mL. In terms of the anti-inflammatory potential, the most effective extract was from a soil-based plant from Jalisco (BS), reduced from nitric oxide in a RAW 264.7 culture medium, with an IC50 value of 134 µg of dry extract/mL. The BS extract showed a significant neutral lipid-reducing activity in the zebrafish model, ranging from 3.13 µg/mL p < 0.05 to 100 µg/mL p < 0.0001. Overall, the extracts analyzed here for the first time seem promising for future use because of their antioxidant, anti-inflammatory and anti-obesity potential.

Importance of high-quality evidence regarding the use of Bacopa monnieri in dementia.

Background: Bacopa monnieri (BM), a commonly used herb, has shown neuroprotective effects in animal and in vitro studies; but human studies on patients with Alzheimer's Disease (AD) have been inconclusive. Further high-quality trials are required to conclusively state the utility of BM in AD and other neurodegenerative dementias. Methods: In the present study, we did a narrative review of the current challenges in designing clinical trials of BM in dementia and their evidence-based recommendations. Results: Many facets of the BM trials need improvement, especially effect size and sample size estimation. Current assessment and outcomes measures need a more holistic approach and newer scales for diagnosing and monitoring prodromal AD. The stringent guidelines in CONSORT and STROBE are often considered difficult to implement for clinical trials in ayurvedic medications like BM. However, adherence to these guidelines will undoubtedly improve the quality of evidence and go a long way in assessing whether BM is efficacious in treating AD/prodromal AD patients and other neurodegenerative dementias. Conclusion: Future studies on BM should implement more randomized controlled trials (RCTs) with an appropriate sample size of accurately diagnosed AD/prodromal AD patients, administering a recommended dosage of BM and for a pre-specified time calculated to achieve adequate power for the study. Researchers should also develop and validate more sensitive cognitive scales, especially for prodromal AD. BM should be evaluated in accordance with the same rigorous standards as conventional drugs to generate the best quality evidence.

Bacopa monnieri reduces Tau aggregation and Tau-mediated toxicity in cells.

Alzheimer's disease is a neurodegenerative disease characterized by progressive memory loss and behavioral impairments. In the present study, the ethanolic extract of Bacopa monnieri was studied for its potency to inhibit Tau aggregation and rescuing of the viability of Tau-stressed cells. Bacopa monnieri was observed to inhibit the Tau aggregation in vitro. The cells exposed to Bacopa monnieri were also observed to have a low level of ROS and caspase-3 activity. The immunoblot and immunofluorescence analysis showed that Bacopa monnieri acts as an antioxidant and restored the Nrf2 levels in Neuro2a cells. Bacopa monnieri treatment to Neuro2a cells was observed to reduce the phospho-Tau load in formaldehyde-stressed cells. Furthermore, the treatment of Bacopa monnieri reduced the phosphorylation of GSK-3ß in formaldehyde-stressed cells. Ran and NUP358 are the key proteins involved in nuclear transport. It was observed that formaldehyde treatment impaired the nuclear transport by missorting the NUP358 arrangement in Neuro2a cells. On the contrary, Bacopa monnieri treatment restored the NUP358 arrangement in cells. The overall results of the present study suggested that Bacopa monnieri could be considered a potent herb against Tau phosphorylation and Tau aggregation, which projects it as a promising formulation for Alzheimer's disease.

Discovery of Molecular Networks of Neuroprotection Conferred by Brahmi Extract in Aß42-Induced Toxicity Model of Drosophila melanogaster Using a Quantitative Proteomic Approach.

Accumulation of Aß42 peptides forming plaque in various regions of the brain is a hallmark of Alzheimer's disease (AD) progression. However, to date, there is no effective management strategy reported for attenuation of Aß42-induced toxicity in the early stages of the disease. Alternate medicinal systems such as Ayurveda in the past few decades show promising results in the management of neuronal complications. Medhya Rasayana such as Brahmi is known for its neuroprotective properties via resolving memory-related issues, while the underlying molecular mechanism of the same remains unclear. In the present study, we aimed to understand the neuroprotective effects of the aqueous extract of Bacopa monnieri and Centella asiatica (both commonly known as Brahmi) against the Aß42 expressing model of the Drosophila melanogaster. By applying a quantitative proteomics approach, the study identified > 90% of differentially expressed proteins from Aß42 expressing D. melanogaster were either restored to their original expression pattern or showed no change in expression pattern upon receiving either Brahmi extract treatment. The Brahmi restored proteins were part of neuronal pathways associated with cell cycle re-entry, apoptosis, and mitochondrial dynamics. The neuroprotective effect of Brahmi was also validated by negative geotaxis behavioral analysis suggesting its protective role against behavioral deficits exerted by Aß42 toxicity. We believe that these discoveries will provide a platform for developing novel therapeutics for AD management by deciphering molecular targets of neuroprotection conferred by an aqueous extract of Bacopa monnieri or Centella asiatica.

Computational Analysis of Bacopa monnieri (L.) Wettst. Compounds for Drug Development against Neurodegenerative Disorders.

AIM: With several experimental studies establishing the role of Bacopa monnieri as an effective neurological medication, less focus has been employed to explore how effectively Bacopa monnieri brings about this property. The current work focuses on understanding the molecular interaction of the phytochemicals of the plant against different neurotrophic factors to explore their role and potential as potent anti-neurodegenerative drugs. BACKGROUND: Neurotrophins play a crucial role in the development and regulation of neurons. Alterations in the functioning of these Neurotrophins lead to several Neurodegenerative Disorders. Albeit engineered medications are accessible for the treatment of Neurodegenerative Disorders, due to their numerous side effects, it becomes imperative to formulate and synthesize novel drug candidates. OBJECTIVE: This study aims to investigate the potential of Bacopa monnieri phytochemicals as potent antineurodegenerative drugs by inspecting the interactions between Neurotrophins and target proteins. METHODS: The current study employs molecular docking and molecular dynamic simulation studies to examine the molecular interactions of phytochemicals with respective Neurotrophins. Further inspection of the screened phytochemicals was performed to analyze the ADME-Tox properties in order to classify the screened phytochemicals as potent drug candidates. RESULTS: The phytochemicals of Bacopa monnieri were subjected to in-silico docking with the respective Neurotrophins. Vitamin E, Benzene propanoic acid, 3,5-bis (1,1- dimethylethyl)- 4hydroxy-, methyl ester (BPA), Stigmasterol, and Nonacosane showed an excellent binding affinity with their respective Neurotrophins (BDNF, NT3, NT4, NGF). Moreover, the molecular dynamic simulation studies revealed that BPA and Stigmasterol show a very stable interaction with NT3 and NT4, respectively, suggesting their potential role as a drug candidate. Nonacosane exhibited a fluctuating binding behavior with NGF which can be accounted for by its long linear structure. ADME-Tox studies further confirmed the potency of these phytochemicals as BPA violated no factors and Vitamin E, Stigmasterol and Nonacosane violated 1 factor for Lipinski's rule. Moreover, their high human intestinal absorption and bioavailability score along with their classification as non-mutagen in the Ames test makes these compounds more reliable as potent antineurodegenerative drugs. CONCLUSION: Our study provides an in-silico approach toward understanding the anti-neurodegenerative property of Bacopa monnieri phytochemicals and establishes the role of four major phytochemicals which can be utilized as a replacement for synthetic drugs against several neurodegenerative disorders.

A comprehensive review on tissue culture studies and secondary metabolite production in Bacopa monnieri L. Pennell: a nootropic plant.

Bacopa monnieri L. Pennell, commonly known as Brahmi, is an important medicinal plant that belongs to the family Plantaginaceae. Brahmi is rich in innumerable bioactive secondary metabolites, especially bacosides that can be employed to reduce many health issues. This plant is used as a neuro-tonic and treatment for mental health, depression, and cognitive performance. Brahmi is also known for its antioxidant, anti-inflammatory, and anti-hepatotoxic activities. There is a huge demand for its raw materials, particularly for the extraction of bioactive molecules. The conventional mode of propagation could not meet the required commercial demand. To overcome this, biotechnological approaches, such as plant tissue culture techniques have been established for the production of important secondary metabolites through various culture techniques, such as callus and cell suspension cultures and organ cultures, to allow for rapid propagation and conservation of medicinally important plants with increased production of bioactive compounds. It has been found that a bioreactor-based technology can also enhance the multiplication rate of cell and organ cultures for commercial propagation of medicinally important bioactive molecules. The present review focuses on the propagation and production of bacoside A by cell and organ cultures of Bacopa monnieri, a nootropic plant. The review also focuses on the biosynthesis of bacoside A, different elicitation strategies, and the over-expression of genes for the production of bacoside-A. It also identifies research gaps that need to be addressed in future studies for the sustainable production of bioactive molecules from B. monnieri.

TiO2 nanoparticle synthesis, characterization and application to shoot regeneration of water hyssop (Bacopa monnieri L. Pennel) in vitro.

Water hyssop (Bacopa monnieri L. Pennel) is a medicinal aquatic herb used to treat diseases in South Asia. Various regeneration protocols have been developed or modified in vitro to ensure the availability of biomass and secondary metabolites of Bacopa. We applied hydrothermally treated titanium dioxide (TiO2) nanoparticles (NPs) (TiO2-NPs) at different concentrations. Three explants, distal portion of half leaf (DPHL), proximal portion of half leaf (PPHL) and full leaf (FL), were used to evaluate response to TiO2. Regeneration from the three explants in vitro was similar except for shoot length. Application of TiO2-NPs exerted significant, but variable, effects on all parameters except percentage of shoot formation, which was 100%. Interactive effects of explant and TiO2-NPs exhibited significant, but variable, effects on fresh weight and percentage of callus formation. All explants produced more shoots using TiO2-NPs compared to control treatments. DPHL explants with application of 8 mg/l TiO2 produced more shoots than controls. Similarly, FL explant treated with 2 mg/l TiO2-NPs produced more shoots/explant than controls. All concentrations of TiO2-NPs produced significantly longer shoots compared to controls. Increased elongation of shoots justifies use of TiO2-NPs for propagation of plants in vitro during acclimatization. Use of TiO2-NPs for rapid elongation of shoots ultimately fosters survival of plants.

Development of a specific and sensitive diagnostic PCR for rapid molecular authentication of the medicinal plant Portulaca oleracea.

Adulteration by Bacopa monnieri (BM) in Portulaca oleracea (PO) plants frequently occurs; it decreases the efficacy of traditional Chinese medicine (TCM) and leads to fraud in the herbal marketplace. In this study, a diagnostic PCR assay was established for the rapid authentication of PO and BM in the herbal market. The sequence divergences in internal transcribed spacer 2 (ITS2) between PO and its adulterant species were used to design diagnostic PCR primers. The specific designed primer sets were evaluated and show that the diagnostic PCR assay can be used to verify the authenticity of PO and BM. The detection limits of the primer set for PO and BM identification were 10 pg and 1 pg, respectively. The reactivity of diagnostic PCR was 0.1% PO genomic DNA and 0.01% BM genomic DNA in the test sample during DNA amplification. In addition, multiplex PCR (mPCR) for PO and BM identification was also established. The samples were more susceptible to the effect of steaming in authentication by singleplex PCR and mPCR than boiling and drying treatment. Furthermore, commercial samples from the market were used to demonstrate the applicability of the developed diagnostic PCR for PO authentication and diagnose BM adulteration, and the investigation found that approximately 72.2% (13/18) of PO plants in the herbal market were adulterated. In conclusion, the diagnostic PCR assay was successfully developed and its specificity, sensitivity and reactivity for PO and BM authentication were proven. These developed PCR-based molecular methods can be applied as an identification tool for PO authenticity and can be practically applied for inspection of BM adulteration in the herbal market in the future.

Bio-Computational Evaluation of Compounds of Bacopa Monnieri as a Potential Treatment for Schizophrenia.

Schizophrenia is a horrible mental disorder characterized by distorted perceptions of reality. Investigations have not identified a single etiology for schizophrenia, and there are multiple hypotheses based on various aspects of the disease. There is no specific treatment for schizophrenia. Hence, we have tried to investigate the updated information stored in the genetic databases related to genes that could be responsible for schizophrenia and other related neuronal disorders. After implementing combined computational methodology, such as protein-protein interaction analysis led by system biology approach, in silico docking analysis was performed to explore the 3D binding pattern of Bacopa monnieri natural compounds while interacting with STXBP1. The best-identified compound was CID:5319292 based on -10.3 kcal/mol binding energy. Further, selected complexes were dynamically evaluated by MDS methods, and the output reveals that the STXBP1-CID:5281800 complex showed the lowest RMSD value, i.e., between 0.3 and 0.4 nm. Hence, identified compounds could be used to develop and treat neuronal disorders after in vivo/in vitro testing.

Herbal tea with bacoside loaded saponins: formulation and characterization for food fortification from Bacopa monnieri L.

In recent times, there is a renewed interest of herbal tea because of growing consumer awareness for the health benefits of herbal tea consumption in the covid era. Bacopa monnieri is a natural medicine mainly used to enhance nerve impulse transmission, improves memory and mental function as well as the enhancement of other cognitive function because of the presence of triterpenoid saponins and bacoside A. The present experiment was conducted for the development of herbal tea with known health benefits from Bacopa monnieri using different spices or herbal ingredients combinations, i.e., Pepper, cardamom, and ginger to increase its aesthetic properties. A higher sensory score for pepper-brahmi was found superior with 8.71 (colour), 8.43 (aroma), 8.43 (taste), 8.29 (after taste), and 8.46 (overall acceptability) over three combinations and control. Jal brahmi tisane revealed, 0.036 ± 0.0004 mg/100 ml Bacoside A, 87.72 mg TE/100 ml TAC, 106.02 mg GAE/100 ml TPC, 21,100 µg/100 ml calcium, and 87 µg/100 ml iron, which is essentially good for human health.

Investigating neuroprotective roles of Bacopa monnieri extracts: Mechanistic insights and therapeutic implications.

Bacopa monnieri (Brahmi) is a well-known perennial, creeping herb of the Indian Ayurveda system; it contains numerous bioactive phytoconstituents implicated in the therapeutic management of several life-threatening diseases. This herb was used by Ancient Vedic scholars due to its pharmacological effect, especially as a nerve tonic and nootropic booster. However, to better understand the roles of Bacopa monnieri extract (BME) in neurological disorders and memory-related diseases, it is necessary to understand its active phytochemical constituents and their molecular mechanisms. Several clinical studies suggested that BME have neuroprotective effects, making it worth revising a notable herb. Here we investigated the contours of BME's phytochemistry and pharmacological features, focusing on neuronal disorders. We further analyzed the underlying molecular mechanisms in therapeutic intervention. Various clinical concerns and synergistic potential of BME were explored for their effective use in cognition and neuroprotection. The generation of reactive oxygen species increases neuroinflammation and neurotoxicity and is associated with Tau and amyloid-beta (Aß) aggregation, leading to a neurological disorder. Our findings provide deeper mechanistic insights into the neuroprotective roles of BME, which can be further implicated in the therapeutic management of neurological disorders and exerting cognitive-enhancing effects.
