RESUMEN
Natural bioactive molecules such as phenolic acids and alkaloids play a crucial role in preserving the quality and safety of food products, particularly oils, by preventing oxidation. Berberis integerrima, a rich source of such antioxidants, has been explored in this study for its potential application in soybean oil preservation. Electrospun nanofibers, composed of polyvinyl alcohol and chitosan, were fabricated and loaded with an alcoholic extract of Berberis integerrima. The antioxidant activity of Berberis integerrima was evaluated, and the phenolic compounds contributing to its efficacy were identified and quantified. The physicochemical properties of the polyvinyl alcohol /chitosan/Berberis integerrima nanofibers, including morphology, crystallinity, functional groups, and thermal stability, were characterized. The results revealed that the polyvinyl alcohol/chitosan/Berberis integerrima nanofibers exhibited high antioxidant capacity and improved the stability of Berberis integerrima, indicating their potential as effective and biodegradable materials for food preservation. This study underscores the potential of harnessing natural antioxidants from Berberis integerrima in nanofibers to enhance the quality and safety of soybean oil.

Berberis vulgaris (L.) has remarkable ethnopharmacological properties and is widely used in traditional medicine. The present study investigated B. vulgaris stem bark (Berberidis cortex) by extraction with 50% ethanol. The main secondary metabolites were quantified, resulting in a polyphenols content of 17.6780 ± 3.9320 mg Eq tannic acid/100 g extract, phenolic acids amount of 3.3886 ± 0.3481 mg Eq chlorogenic acid/100 g extract and 78.95 µg/g berberine. The dried hydro-ethanolic extract (BVE) was thoroughly analyzed using Ultra-High-Performance Liquid Chromatography coupled with High-Resolution Mass Spectrometry (UHPLC-HRMS/MS) and HPLC, and 40 bioactive phenolic constituents were identified. Then, the antioxidant potential of BVE was evaluated using three methods. Our results could explain the protective effects of Berberidis cortex EC50FRAP = 0.1398 mg/mL, IC50ABTS = 0.0442 mg/mL, IC50DPPH = 0.2610 mg/mL compared to ascorbic acid (IC50 = 0.0165 mg/mL). Next, the acute toxicity and teratogenicity of BVE and berberine-berberine sulfate hydrate (BS)-investigated on Daphnia sp. revealed significant BS toxicity after 24 h, while BVE revealed considerable toxicity after 48 h and induced embryonic developmental delays. Finally, the anticancer effects of BVE and BS were evaluated in different tumor cell lines after 24 and 48 h of treatments. The MTS assay evidenced dose- and time-dependent antiproliferative activity, which was higher for BS than BVE. The strongest diminution of tumor cell viability was recorded in the breast (MDA-MB-231), colon (LoVo) cancer, and OSCC (PE/CA-PJ49) cell lines after 48 h of exposure (IC50 < 100 µg/mL). However, no cytotoxicity was reported in the normal epithelial cells (HUVEC) and hepatocellular carcinoma (HT-29) cell lines. Extensive data analysis supports our results, showing a significant correlation between the BVE concentration, phenolic compounds content, antioxidant activity, exposure time, and the viability rate of various normal cells and cancer cell lines.

Berberis vulgaris L. (Berberidaceae) is a shrub that has been widely used in European folk medicine as an anti-inflammatory and antimicrobial agent. The purpose of our study was to elucidate the mechanisms of the chemopreventive action of the plant's methanolic root extract (BVR) against colon cancer cells. Studies were conducted in human colon adenocarcinoma cell lines (LS180 and HT-29) and control colon epithelial CCD841 CoN cells. According to the MTT assay, after 48 h of cell exposure, the IC50 values were as follows: 4.3, 46.1, and 50.2 µg/mL for the LS180, HT-29, and CCD841 CoN cells, respectively, showing the greater sensitivity of the cancer cells to BVR. The Cell Death Detection ELISAPLUS kit demonstrated that BVR induced programmed cell death only against HT-29 cells. Nuclear double staining revealed the great proapoptotic BVR properties in HT-29 cells and subtle effect in LS180 cells. RT-qPCR with the relative quantification method showed significant changes in the expression of genes related to apoptosis in both the LS180 and HT-29 cells. The genes BCL2L1 (126.86-421.43%), BCL2L2 (240-286.02%), CASP3 (177.19-247.83%), and CASP9 (157.99-243.75%) had a significantly elevated expression, while BCL2 (25-52.03%) had a reduced expression compared to the untreated control. Furthermore, in a panel of antioxidant tests, BVR showed positive effects (63.93 ± 0.01, 122.92 ± 0.01, and 220.29 ± 0.02 mg Trolox equivalents (TE)/g in the DPPHâ¢, ABTSâ¢+, and ORAC assays, respectively). In the lipoxygenase (LOX) inhibition test, BVR revealed 62.60 ± 0.87% of enzyme inhibition. The chemical composition of BVR was determined using a UHPLC-UV-CAD-MS/MS analysis and confirmed the presence of several known alkaloids, including berberine, as well as other alkaloids and two derivatives of hydroxycinnamic acid (ferulic and sinapic acid hexosides). The results are very promising and encourage the use of BVR as a comprehensive chemopreventive agent (anti-inflammatory, antioxidant, and pro-apoptotic) in colorectal cancer, and were widely discussed alongside data from the literature.

BACKGROUND: Acne vulgaris is one of the most common dermatological disorders. Berberis integerrima Bunge belongs to the Berberidaceae family. Several studies on different Berberis species in addition to B. integerrima have shown antimicrobial, antioxidant, and anti-inflammatory effects. Spearmint essential oil also has antioxidant, antibacterial, and anti-inflammatory activities. This study aimed to evaluate the clinical effectiveness of the topical combination of B. integerrima root extract and spearmint essential oil in the treatment of acne vulgaris. METHODS: Patients with mild to moderate facial acne who met the inclusion criteria were randomly assigned to either drug (B. integerrima extract/spearmint essential oil topical solution) or control (clindamycin 1% topical solution) groups. Each group applied the solution twice a day for 4 weeks. Before and at the end of the intervention, the number of lesions and mGAGS (Modified Global Acne Grading Scale) score were recorded. RESULTS: Thirty patients in each group of drug and control completed the study. Topical B.integerrima root extract/spearmint essential oil significantly reduced the number of lesions (27.33 ± 26.17 vs. 21.58 ± 21.10; p < 0.001) and mGAGS (18.76 ± 8.61 vs. 13.87 ± 8.14; p < 0.001) at the end of the intervention. However, there was no significant difference between the two groups regarding the number of lesions (p = 0.906) and mGAGS (p = 0.882). CONCLUSIONS: B. integerrima root extract combined with spearmint essential oil has significant anti-acne effects, comparable to topical antibiotic clindamycin. It could be considered as a potential treatment for acne vulgaris. However, more studies with larger sample sizes and longer durations are required to confirm this effect.

OBJECTIVES: Oxidative stress has a key role in the diabetes pathogenesis and complications. Berberis vulgaris is known in folk medicine for curing several diseases. The current research aimed to assess the influences of Berberis vulgaris fruit extract against oxidative stress in streptozotocin-induced diabetic rats. METHODS: Streptozotocin (60â¯mg/kg, ip) was injected to male rats. After diabetes confirmation, animals received the Berberis vulgaris fruit extract daily at amounts of 3.5 and 7.5â¯% of drinking water (v/v) for six weeks. Total thiol and lipid peroxidation levels were assessed in the serum, liver, kidney and spleen at the end of the study. RESULTS: Diabetic rats exhibited hyperglycemia along with enhancement of lipid peroxidation levels in the serum, liver, kidney and spleen, and decrement of total thiol content in the kidney and liver tissues. Chronic administration of Berberis vulgaris fruit extract at amount of 3.5â¯% of drinking water decreased the lipid peroxidation level in the serum and liver, and enhanced total thiol level in the liver and kidney. CONCLUSIONS: Berberis vulgaris fruit extract exerts antioxidant activity in the serum, liver and kidney organs of diabetic rats. Therefore, it might be used in the prevention and control of diabetes complications.

OBJECTIVE: Berberis lycium is an indigenous plant of Pakistan that is known for its medicinal properties. In the current study, we investigated the anti-Alzheimer's effect of berberine isolated from Berberis lycium. METHODS: Root extract of B. lycium was subjected to acetylcholinesterase inhibition assay and column chromatography for bioassays guided isolation of a compound. The neuroprotective and memory improving effects of isolated compound were evaluated by aluminium chloride induced Alzheimer's disease rat model, elevated plus maze (EPM) and Morris water maze (MWM) tests., Levels of dopamine and serotonin in rats brains were determined using HPLC. Moreover, western blot and docking were performed to determine interaction between berberine and ß-secretase. RESULTS: During fractionation, ethyl acetate and methanol (3:7) fraction was collected from solvent mixture of ethyl acetate and methanol. This fraction showed the highest anti-acetylcholinesterase activity and was alkaloid positive. The results of TLC and HPLC analysis indicated the presence of the isolated compound as berberine. Additionally, the confirmation of isolated compound as berberine was carried out using FTIR and NMR analysis. In vivo EPM and MWM tests showed improved memory patterns after berberine treatment in Alzheimer's disease model. The levels of dopamine, serotonin and activity of antioxidant enzymes were significantly (p<0.05) enhanced in brain tissue homogenates of berberine treated group. This was supported by decreased expression of ß-secretase in berberine treated rat brain homogenates and good binding affinity of berberine with ß-secretase in docking studies. Binding energies for interaction of ß-secretase with berberine and drug Rivastigmine is -7.0 kcal/mol and -5.8 kcal/mol respectively representing the strong interactions. The results of docked complex of secretase with berberine and Rivastigmine was carried out using Gromacs which showed significant stability of complex in terms of RMSD and radius of gyration. Overall, the study presents berberine as a potential drug against Alzheimer's disease by providing evidence of its effects in improving memory, neurotransmitter levels and reducing ß-secretase expression in the Alzheimer's disease model.

Enhancements in bioceramic mixtures represent a significant avenue for achieving superior mechanical and biological properties. Therefore, the present study aimed to extract active compounds from Berberis vulgaris stems and fruits collected from the Khorasan province, employing advanced analytical techniques such as GC-MS and FTIR to elucidate the composition of these extracts. The derived extracts were utilized to synthesize novel nanocomposites, denoted as SiO2-MPS-stem extract and SiO2-MPS-fruit extract. Comprehensive Characterization of these composites was conducted through SEM, EDX mapping, FTIR, and XRD analyses. The characterization measurements validated the successful coating of silica with the extracts, resulting in a core-shell nanostructure with particle sizes below 60 nm. These composites were incorporated into bioceramics for dental root fillings with an equal weight ratio. The bioceramic material was subjected to the same aforementioned characterization techniques, revealing that their sizes fell within the nanoscale range, not exceeding 70 nanometers. The results indicated a core-shell configuration for the nanomaterials, with the shell comprising the bioceramic component of bioceramic-SiO2-MPS-fruit extract and bioceramic-SiO2-MPS-stem extract.

ETHNOPHARMACOLOGICAL RELEVANCE: Berberis aristata (BA) has been described in Ayurveda in formulations for treating conditions related to the buccal cavity, including tumours and inflammation. Oral cancer (OC) is a major global health problem with high rates of recurrence and metastasis. Natural product based therapies are being explored as safer therapeutic strategies for OC. AIM OF THE STUDY: Evaluating the potential of standardized BA extract loaded buccal spray formulation in OC. MATERIAL AND METHODS: BA stem bark extract was prepared using sonication and standardized with respect to Berberine. The standardized extract was characterized and formulated as a buccal spray (SBAE-BS) using hydroxyl propyl methyl cellulose K15M, polyethylglycol 400, Miglyol®812N and ethanol. The SBAE-BS was characterized and evaluated in vitro in KB cell line and in vivo in OC hamster model. RESULTS: The SBAE-BS had pH, viscosity, mucoadhesive strength and BBR content corresponding to 6.8, 25.9 cP, 345 dyne/cm2 and 0.6 mg/mL respectively. In vitro cytotoxicity of SBAE-BS was comparable to 5 fluorouracil (5FU). In hamsters, SBAE-BS treatment lead to tumour regression (p = 0.0345), improved body weights (p < 0.0001), no organ toxicity, downregulation of inflammatory mediators and improved survival outcomes as compared to standard systemic 5FU. CONCLUSION: Thus, SBAE-BS showed cytotoxic and chemo-protective effects in the OC hamster model, evidencing its ethnopharmacological use and demonstrating translational potential to be developed as therapy for OC.

In search of novel potential drug candidates that could be used as treatments or prophylactics for memory impairment, an aporphine alkaloid magnoflorine (MAG) isolated from the root of Berberis vulgaris was proven to exhibit beneficial anti-amnestic properties. Its effects on immunoreactivity to parvalbumin in the mouse hippocampus were assessed together with a study on its safety and concentration in the brain and plasma. For this purpose, four experimental groups were created: the MAG10 group-treated with 10 mg MAG/kg b.w. i.p., the MAG20 group-treated with 20 mg MAG/kg b.w. i.p., the MAG50 group-treated with 50 mg MAG/kg b.w. i.p., and a control group-injected with saline i.p. at a volume corresponding to their weight. Our results indicated that the hippocampal fields CA1-CA3 were characterized by an elevated number of parvalbumin-immunoreactive neurons (PV-IR) and nerve fibers in mice at the doses of 10 and 20 mg/kg b.w. (i.p.). No significant changes to the levels of IL-1ß, IL-6 or TNF-α were observed for the above two doses; however, the administration of 50 mg/kg b.w. i.p. caused a statistically significant elevation of IL-6, IL-1beta plasma levels and an insignificant raise in the TNF-alpha value. The HPLC-MS analysis showed that the alkaloid's content in the brain structures in the group treated with 50 mg/kg b.w. did not increase proportionally with the administered dose. The obtained results show that MAG is able to influence the immunoreactivity to PV-IR in hippocampal neurons and might act as a neuroprotective compound.

INTRODUCTION: The root bark of Berberis aristata has been utilized by indigenous peoples for wound treatment for centuries. The mature root barks are crushed into a paste and applied to the wound's surface. OBJECTIVE: The focus of this research is to analyse the wound healing activities of an ethanolic extract of Berberis aristata, as well as to use molecular docking to establish the likely mechanism of the potent phytochemical. There is no scientific evidence to support the usage of root bark extract of Berberis aristata. METHODS: The Herbal ointment, which comprises (1%, 2%, and 4% w/w) ethanolic extract of root bark, was developed to test the wound healing ability of incision and excision wounds, and the molecular mechanism was established using Auto-Dock software. RESULTS: Epithelization stage, wound index, % wound contraction area, hydroxyproline content, DNA estimate, and histopathological assessments were performed on the incision wound model. Tensile strength was assessed in an excision wound model. TLC was used to identify the samples after successive extractions with different solvents based on polarity. CONCLUSION: Berberine and tetrahydropalmatine were major active phytoconstituent found in root barks of Berberis aristata as secondary metabolites. Animals treated with 4% w/w formulation demonstrated considerable wound contraction, epithelization time, and wound index in the excision model. In contrast, to control and standardize the concentrations of hydroxyproline, total amino acids, and DNA in recovering tissue were higher. At 4% w/w extract formulation, the parameters studied indicated a substantial result. Berberine and tetrahydropalmatine, active metabolites which are present in the ethanolic extract of Berberis aristata, were found to be responsible for wound healing. Based on ligand interactions, the findings verified Berberis aristata ethnomedicinal claim in a wound healing capacity.

Background/aim: This study aimed to determine the proliferation and apoptotic effects of extracts from Cornus mas L. and Berberis vulgaris fruits on human breast cancer cells (MCF-7). Materials and methods: The Cornus mas L. and Berberis vulgaris fruits, which constitute the herbal material of the study, were turned into 80% acetone extract after washing. The total phenolic content in Berberis vulgaris fruit extracts was determined calorimetrically using Folin-Ciocalteu reagent. The spectrophotometric method was used to determine the total flavonoid amount of the extracts. In order to measure the antioxidant capacity of Cornus mas L. and Berberis vulgaris fruits and extracts, DPPH Radical Scavenging Power test and Cu (II) ion reducing antioxidant capacity method were applied. Cell viability rates were determined by the XTT method. Flow cytometric measurement was performed to examine the apoptotic role of the extracts in the cell by using the Annexin-V/7-AAD commercial kit. Results: According to the data, Berberis vulgaris fruit extract appeared more effective on MCF-7 breast cancer cells in both 24 and 48 hours of exposure. Analyses made to examine the phenolic component and antioxidant capacity properties of the fruits used in the study and the results we encountered when we exposed the cell were found to be compatible with each other. Annexin-V/7-AAD method showed that the apoptotic effects of the extracts in 48 hour exposures were more effective. Conclusion: It has been determined that Cornus mas L. and Berberis vulgaris fruits, which are rich in phenolic components with high flavonoid content and high antioxidant capacities, support the apoptosis of cancer cells.

A comprehensive study of bioactive compounds was carried out in the leaves of the main Berberis species growing in Chile (Berberis microphylla, Berberis darwinii, Berberis empetrifolia, Berberis trigona, and the introduced Berberis vulgaris). We identified 117 compounds, by a detailed analysis of each molecule, including phenolic acids, alkaloids, flavonols, and other compounds, using high-performance liquid chromatography and high-resolution mass spectrometry. Quantitative analysis of main compound was also included for all species. Hydroxycinnamic acid derivatives were the main compounds in all the studied leaves, with the highest concentration in Berberis microphylla. Quercetin derivatives were the most relevant flavonols in all species, except in Berberis vulgaris, in which isorhamnetin-3-rutinoside was the most concentrated. The fatty acid profile, determined by gas chromatography mass spectrometry revealed the presence of linoleic and linolenic acids in all species studied. Berberis vulgaris showed higher levels of these fatty acids. The antioxidant capacity, explored by three in vitro methods, showed high values for all studied Berberis species. The obtained levels are higher than those of other prominent foods. The findings will inform novel approaches for the valorization of these leaves as natural food or ingredient.

This study evaluates the antibacterial activity and phytochemical characterizations of Andrographis paniculata extract (APE) and Berberis aristata extract (BAE). The stem of Andrographis paniculata (AP) and root of Berberis aristata (BA) were extracted with methanol. The results confirmed that APE and BAE possess high phenolic and flavonoid content. The antioxidant activity of the APE and BAE showed an elevated potential to scavenge DPPH (2,2-diphenyl-1-picrylhydrazyl) radicals with IC50 of 95.03 µg/mL and 256.26 µg/mL, respectively. A total of 35 and 32 metabolites in APE and BAE, respectively, were identified through mass spectrometry analysis, whereas 17 and 12 metabolites in APE and BAE, respectively, were detected through high-performance thin-layer chromatography (HPTLC) fingerprinting profiling. Antibacterial activity of the extracts was performed by the well diffusion and microdilution method, and the findings showed that APE and BAE had antibacterial activities against E. coli and S. aureus. The growth curve and time-kill study showed that the extracts had a bacteriostatic effect. A combination study with the standard drug was carried out using the microdilution checkerboard method in which most of the combinations showed synergistic interactions. The findings of this study have shown that APE and BAE are good sources of antibacterial compounds and can be used for treating infectious diseases caused by E. coli and S. aureus.

BACKGROUND: The plant Berberis aristata is traditionally used and scientifically validated for treating obesity and hyperlipidemia. It is also traditionally used to treat gynecological abnormalities. Therefore, the present study was designed to evaluate the therapeutic potential of Berberis aristata for obesity-related reproductive changes and chemically characterize it. METHODS: High-fat diet was given to 36 female rats for six weeks to induce obesity and infertility. These obese rats were treated with 10 mg/kg orlistat or the plant extract at 125-500 mg/kg for 45 days. RESULTS: The GC-MS analysis of the plant extract included fructose, thymic acid and other hydrocarbons. The plant extract revealed a remarkable free radical scavenging activity. The treated animals exhibited a decrease in total cholesterol and triglycerides (p<0.001), insulin and leptin levels (p<0.05), visceral fat, and body weight while increasing the estradiol level at 500 mg/kg dose of the plant extract as compared with untreated animals as demonstrated from the histology of the ovary. Oxidative stress biomarkers such as superoxide dismutase, nitric oxide, malondialdehyde and reduced glutathione were significantly (p<0.01-0.001) ameliorated in treated rats. CONCLUSION: B. aristata exhibited substantial potential against obesity-inducedreproductive damage in female rats by reducing oxidative stress and resistance to leptin and insulin.

Wild fruits have increasingly been investigated as part of recent searches for food products with a high antioxidant activity. In this study, wild edible berberis Berberis vulgaris collected from three different provinces (Jilin, Heilongjiang, and Liaoning) were investigated for their phenolic contents, organic acid contents, mineral contents, antioxidant activity as well as their antimicrobial potential against a range of common food borne pathogens. In addition, a physiochemical and mineral analysis of the fruits was also performed. The methanol extracts of berberis fruit collected from Jilin province were highly active against all the studied food borne bacterial pathogens, i.e., S. aureus and L. monocytogenes, E. coli, P. fluorescens, V. parahaemolyticus, and A. caviae while the berberis extracts from Heilongjiang and Liaoning showed activity only against Gram-negative bacteria. The phenolic content and antioxidant activity were determined by the HPLC separation method and ß-carotene bleaching methods, respectively. Four organic acids such as malic acid, citric acid, tartaric acid, and succinic acid were identified while a variety of phenolic compounds were detected among which catechin, chlorogenic acid, and gallic acid were found to be the predominant phenolic compounds in all three of berberis fruit samples. The berberis fruit from Jilin was found to be superior to the Heilongjiang and Liaoning fruit regarding desired physiochemical analysis; however, there were no significant differences in the mineral contents among the three samples. Overall, the berberis fruit from Jilin was ranked as the best in term of the nutritional, physiochemical, antimicrobial, and antioxidant properties. This study confirms the various useful characteristics and features of berberis at a molecular level that can be used as a sustainable source for their potential nutritional applications for making functional foods in different food industries.

Antioxidants are materials that scavenge or remove free radicals from living systems. The oxidation process ends in the production of free radicals. These free radicals are the chief birthplace of cancerous cells. Antioxidizing agents remove free radical intermediates by terminating oxidation processes by being oxidized themselves. On the other hand, infectious diseases affect the world on a large scale. To fight these diseases several synthetic compounds have been used. Plant based medications play important role in this regard. So, the current research aimed to investigate the antibacterial and antioxidant effect of Berberis lycium Royle root bark (BLR) extract. Berberis lycium Royle was used for phytochemical analysis and also as antimicrobial and antioxidant agents. The antimicrobial activity was evaluated by the agar well diffusion method. Current study revealed that BLR was rich in phytochemicals and toxic against tested pathogenic bacteria. BLR showed the highest activity against S. pyogenes (13.3±0.8 mm). The lowest antibacterial activity was reported against E. coli (0±0 mm). In case of minimum inhibitory concentration, it was observed that BLR with 10 µg/mL concentration showed the highest activity while 2.5 µg/mL of BLR showed the least inhibitory activity. The highest In vitro antioxidant activity was recorded as 65% at 100 µg/mL. In case of in vivo antioxidant activity level of CAT, GSH and SOD were decreased while that of MDA was enhanced in groups treated with CCl4 as compared to the control group. BLR extract treatment reversed all these changes significantly. Current results indicate that BLR is effective against bacterial pathogens and also has antioxidant potential.

ETHNOPHARMACOLOGICAL RELEVANCE: Berberis integerrima commonly known as "barberry" belongs to the Berberidaceae family and has been used as a medicinal plant in Iranian traditional medicine. AIM OF THE STUDY: Our aim in this study was to investigate the effects of barberry consumption on blood pressure (BP). MATERIALS AND METHODS: Eighty-four medicated hypertensive patients were selected and randomly allocated to barberry and placebo groups. The barberry group received 10 g/day dried purple-black barberry powder, once daily, for 2-months. Systolic, diastolic, and mean arterial BP was assessed through 24-h ambulatory BP monitoring before and after 2-month treatment. The estimation of sodium and potassium intake was done through measurement of sodium and potassium in 24-h urinary samples. Plasma and urinary nitrite, and nitrate (NOx) levels, as well as plasma angiotensin-converting enzyme (ACE) activity, were also determined. RESULTS: Seventy-eight participants with an average age of 54.12 ± 10.32 years and BMI of 27.93 ± 2.22 kg/m2 completed the study. There was no significant difference in body weight, physical activity, and the 24-h urinary sodium and potassium excretion between the two groups before and after the study. After adjusting for baseline values and changes in sodium intake, systolic, and mean arterial BP decreased significantly in the barberry group compared to the placebo group (p = 0.015 and p = 0.008, respectively). Plasma NOx levels and ACE activity were not different between the two groups, but urinary NOx was increased significantly in the barberry group compared to the placebo group (p = 0.008). CONCLUSIONS: In patients treated with antihypertensive drugs, daily consumption of purple-black barberry can be effective in improving systolic BP control.

Since ancient times the medicinal plants have been under use as food and potential therapeutic agent for the management of overall health and the use of all plant parts including fruits, seeds, is well reported in the literature. One such plant is Berberis aristata which is rich in vitamins, minerals, and various phytochemicals amongst which Berberine is the principal bioactive compound with a range of reported health benefits, and some of the commercial formulations like Rasaut, Darvyadi Leha are being used for the treatments of jaundice, malaria, typhoid fever, inflammation, eye infection, diarrhea, wound healing, etc. The hepatoprotective, antidiabetic, antitumor, anti-cancerous, properties are the recent additions to its functional importance. Berberine has significant bioactivities in the treatments of different diseases. Besides its remarkable applications, the berberine has low efficacy due to its low solubility in water, poor absorption, and low bioavailability. This problem can be solved by using some techniques like Nanotechnology which has been found to increase its solubility in water, bioavailability, and absorption and hence provide a better delivery system of berberine. This review illuminates the therapeutic applications of the plant Berberis aristata, scientific validation to its traditional uses, role of berberine in the treatment of various diseases through its different bioactivities, major flaws in berberine treatment, and the role of nanotechnology in minimizing those flaws and increasing its overall efficacy.Key teaching pointsPlant Berberis aristata has been used since ancient times for the treatment of various ailments like jaundice, hepatitis, fever, bleeding, inflammation, diarrhea, malaria, skin and eye infections, chronic rheumatism, and urinary disorders.Berberine is the major and most significant phytochemical among numerous phytochemicals present in plant Berberis aristata.Berberine has significantly shown many potent effect against emerging diseases like cancer and diabetes. Besides that, it has also shown antioxidant, anti-inflamation, antimicrobial, hepatoprotective, and anti-gastrointestinal disorder properties.Berberine can be very effective in overcoming the demerits of berberine treatment like poor aqueous solubility, low bioavailability, and poor absorption in the human body in the treatment of various diseases.

The dried stem bark of Berberis kansuensis is a commonly used Tibetan herbal medicine for the treatment of diabetes. Its main chemical components are alkaloids, such as berberine, magnoflorine and jatrorrhizine. However, the role of gut microbiota in the in vivo metabolism of these chemical components has not been fully elucidated. In this study, an ultra-high performance liquid chromatography method coupled with Orbitrap mass spectrometry (UHPLC-Orbitrap-MS) technology was applied to detect and identify prototype components and metabolites in rat intestinal contents and serum samples after oral administration of a B. kansuensis extract. A total of 16 prototype components and 40 metabolites were identified. The primary metabolic pathways of the chemical components from B. kansuensis extract were demethylation, desaturation, deglycosylation, reduction, hydroxylation, and other conjugation reactions including sulfation, glucuronidation, glycosidation, and methylation. By comparing the differences of metabolites between diabetic and pseudo-germ-free diabetic rats, we found that the metabolic transformation of some chemical components in B. kansuensis extract such as bufotenin, ferulic acid 4-O-ß-D-glucopyranoside, magnoflorine, and 8-oxyberberine, was affected by the gut microbiota. The results revealed that the gut microbiota can affect the metabolic transformation of chemical constituents in B. kansuensis extract. These findings can enhance our understanding of the active ingredients of B. kansuensis extract and the key role of the gut microbiota on them.

Interest in medicinal plants and fruits has increased in recent years due to people beginning to consume natural foods. This study aims to investigate the total phenolic flavonoid content, antioxidant activity, condensed tannin content, oil content, and fatty acid compositions of five local breeds of Berberis spp. from Bayburt, Turkey, and their antioxidant and antimicrobial activities. The fatty acid composition of samples was performed with gas chromatography-mass spectrometry (GC-MS), and the total fatty acid content of samples was between 6.12% and 8.60%. The main fatty acids in Berberis spp. samples were α-linolenic acid (32.85-37.88%) and linoleic acid (30.98-34.28%) followed by oleic acid (12.85-19.56%). Two antioxidant assays produced similar results, demonstrating that extracts of wild B. vulgaris L. had the highest ferric reducing antioxidant power (FRAP) (621.02 µmol FeSO4.7H2O/g) and 1,1-diphenyl-2-picrylhydrazyl radical (DPPH) (0.10 SC50 mg/mL) values. According to principal component analysis (PCA), four components were determined. In addition, two main groups were determined according to hierarchical cluster analysis (HCA), and wild and culture of B. vulgaris L. were in different subgroups. This is the first original report about the fatty acid composition and oil content of Berberis spp. grown in Bayburt, Turkey. The obtained results indicate that B. integerrima Bunge and B. vulgaris, which have especially remarkable fatty acid content, antioxidant, and antimicrobial activity, could be potential sources for these properties in different areas of use.
