Antibacterial effect of Moringa oleifera on Staphylococcus aureus and Pseudomonas aeruginosa isolated from raw milk and some dairy products with special reference to biofilm gene expression.

Background: Pseudomonas aeruginosa (P. aeruginosa) and Staphylococcus aureus (S. aureus) are well defined as food poisoning pathogens that are highly resistant and need continuous studies. Aim: The purpose of the work was to examine phenotypic and genotypic characteristics of both P. aeruginosa and S. aureus, and treatment trials with medicinal plants. Methods: Samples were examined for isolation of P. aeruginosa and S. aureus on selective media followed by biochemical confirmation, biofilm formation, genes detection, and expression of P. aeruginosa pslA biofilm gene was performed by quantitative real-time polymerase chain reaction after treatment with 0.312 mg/ml Moringa oleifera aqueous extract as a minimum inhibitory concentration. Results: The highest isolation rate of P. aeruginosa was 20% from both raw milk and Kariesh cheese, followed by 16% and 12% from ice cream and processed cheese, respectively, while the highest isolation rate of S. aureus was 36% from raw milk followed by 28% in ice cream and 16% in both Kariesh cheese and processed cheese. 30% of P. aeruginosa isolates were biofilm producers, while only 21% of S. aureus isolates were able to produce biofilm. The P. aeruginosa isolates harbor virulence-associated genes nan1, exoS, toxA, and pslA at 100%, 80%, 40%, and 40%, respectively. Staphylococcus aureus SEs genes were examined in S. aureus strains, where SEA and SEB genes were detected with 60%, but no isolate harbored SEC, SED, or SEE. The significant fold change of P. aeruginosa pslA expression was 0.40332 after treatment with M. oleifera aqueous extract. Conclusion: Pseudomonas aeruginosa and S. aureus harbor dangerous virulence genes that cause food poisoning, but M. oleifera extract could minimize their action.

Moringa oleifera and Its Biochemical Compounds: Potential Multi-targeted Therapeutic Agents Against COVID-19 and Associated Cancer Progression.

The Coronavirus disease-2019 (COVID-19) pandemic is a global concern, with updated pharmacological therapeutic strategies needed. Cancer patients have been found to be more susceptible to severe COVID-19 and death, and COVID-19 can also lead to cancer progression. Traditional medicinal plants have long been used as anti-infection and anti-inflammatory agents, and Moringa oleifera (M. oleifera) is one such plant containing natural products such as kaempferol, quercetin, and hesperetin, which can reduce inflammatory responses and complications associated with viral infections and multiple cancers. This review article explores the cellular and molecular mechanisms of action of M. oleifera as an anti-COVID-19 and anti-inflammatory agent, and its potential role in reducing the risk of cancer progression in cancer patients with COVID-19. The article discusses the ability of M. oleifera to modulate NF-κB, MAPK, mTOR, NLRP3 inflammasome, and other inflammatory pathways, as well as the polyphenols and flavonoids like quercetin and kaempferol, that contribute to its anti-inflammatory properties. Overall, this review highlights the potential therapeutic benefits of M. oleifera in addressing COVID-19 and associated cancer progression. However, further investigations are necessary to fully understand the cellular and molecular mechanisms of action of M. oleifera and its natural products as anti-inflammatory, anti-COVID-19, and anti-cancer strategies.

The effect of Channa striata, Moringa oleifera, and Curcuma xanthorrhiza extract on accelerating recovery in a ventilated patient with hemorrhagic shock grade 3 due to prolonged retained placenta: a case report.

BACKGROUND: Most of critically ventilated patients with severe hemorrhagic shock experience metabolic acidosis, hypoalbuminemia, electrolyte imbalance, and increased production of free radical. Channa striata has a high content of albumin, an essential binding protein that contributes to homeostasis, and when combined with Moringa oleifera and Curcuma xanthorrhiza, they act as powerful antioxidants. Administration of C. striata, M. oleifera, and C. xanthorrhiza extract orally may benefit patient with hemodynamic issues, including significant blood loss. CASE REPORT: A 40-year-old Indonesian woman came to emergency department with decreased consciousness resulting from hemorrhagic shock grade 3 due to prolonged placenta retention for 10 days after delivery of her third child. She had an emergency hysterectomy and was sent to the intensive care unit with a hemoglobin level of 4.2 gr/dL, despite already receiving two bags of packed red blood cells during operation, and she continued with four more bags within her first day in the intensive care unit. The patient was ventilated, was supported by vasopressors, and had a low albumin level of 2.1 gr/dL. Her hemodynamic profile was difficult to stabilize, with persistent gastric residue and periodic urine output less than 1 cc/kg/hour, thereby slowing the ventilator and vasopressor weaning process. Oral supplementation of C. striata, M. oleifera, and C. xanthorrhiza was given in the second day divided in three doses every 6 hours. After the second dose, gastric residue started to subside and disappeared after the third dose. The patient's condition improved in the next 24 hours; she was extubated and discharged from the hospital in the fourth day. CONCLUSION: This is the first case report describing the effect of C. striata, M. oleifera, and C. xanthorrhiza extract in a patient with severe hemorrhagic shock due to a prolonged placenta. Accelerated recovery showed the possibility benefit of C. striata, M. oleifera, and C. xanthorrhiza extract in stabilizing oncotic pressure, neutralizing free radicals, and preventing further damage in hypoxic cells.

A Safe One-Pot Synthesis and Characterization of Epoxidized Moringa Oleifera Oil.

Global demand for epoxidized vegetable oil has been steadily growing. Epoxidized vegetable oils are typically produced using a two-pot synthesis process in which the oxidation and epoxidation reactions are carried out sequentially. This two-pot synthesis method, however, has a major drawback in industrialscale production, particularly when it comes to operational and process safety issues. A laboratory-scale one-pot synthesis method was attempted in this study with the aim to safely synthesize epoxidized Moringa Oleifera oil (eMOo) by avoiding the occurrence of undesired exothermic runaway reaction. The oil extracted from Moringa Oleifera oil seed kernel (MOo) was used as a starting component due to its high degree of unsaturation and also because the Moringa Oleifera plant can be freely grown in any soil conditions. Two parallel oxidation and epoxidation reactions were carried out simultaneously in this one-pot synthesis method to produce eMOo. The effect of five different mole ratios of MOo, acetic acid and hydrogen peroxide (1:1:1, 1:1:2, 1:1.5:2, 1:1.75:2 and 1:2:2, respectively) on reaction mechanism was investigated at the controlled temperature range of 43 - 55°C and reaction time of 0 - 120 min. The physicochemical properties of MOo as well as the oxirane oxygen content (OOC) of the resulting eMOo were characterized. In addition, GC-MS and FTIR analysis were performed to verify the molecular composition of MOo and also to identify the epoxy group of the resulting eMOo respectively. Among the five different mole ratios studied, the 1:1.5:2 mole ratio has the highest unsaturation conversion of 79.57% and OOC of 4.12%.

Phytochemical Profiling by UHPLC-Q-TOF/MS and Chemopreventive Effect of Aqueous Extract of Moringa oleifera Leaves and Benzyl Isothiocyanate on Murine Mammary Carcinogenesis.

Moringa oleifera Lam, commonly known as moringa, is a plant widely used both as a human food and for medicinal purposes around the world. This research aimed to evaluate the efficacy of the aqueous extract of Moringa oleifera leaves (MoAE) and benzyl isothiocyanate (BIT) in rats with induced breast cancer. Cancer was induced with 7,12-dimethylbenz[a]anthracene (DMBA) at a dose of 60 mg/kg by orogastric gavage once only. Forty-eight rats were randomly assigned to eight groups, each consisting of six individuals. The control group (healthy) was called Group I. Group II received DMBA plus saline. In addition to DMBA, Groups III, IV, and V received MoAE at 100, 250, and 500 mg/kg/day, respectively, while Groups VI, VII, and VIII received BIT at 5, 10, and 20 mg/kg/day, respectively. Treatment was carried out for 13 weeks. Secondary metabolite analysis results identified predominantly quercetin, caffeoylquinic acid, neochlorogenic acid, vitexin, and kaempferol, as well as tropone, betaine, loliolide, and vitexin. The administration of MoAE at a dose of 500 mg/kg and BIT at 20 mg/kg exhibited a notable decrease in both the total tumor count and the cumulative tumor weight, along with a delay in their onset. Furthermore, they improved the histological grade. A significant decrease in serum levels of VEGF and IL-1ß levels was observed (p < 0.001) with a better effect demonstrated with MoAE at 500 mg/kg and BIT at 20 mg/kg. In conclusion, this study suggests that both the aqueous extract of Moringa oleifera leaves and the benzyl isothiocyanate possess antitumor properties against mammary carcinogenesis, and this effect could be due, at least in part, to the flavonoids and isothiocyanates present in the extract.

Impacts of microwave-assisted extraction parameters on total phenolic compounds yield from Algerian Moringa oleifera leaves, using response surface methodology.

The study aimed to optimise the microwave-assisted extraction (MAE) of total phenolic compounds (TPC) from Moringa oleifera Lam. leaves using response surface methodology (RSM) and Box-Behnken designs (BBD). Factors such as ethanol concentration, microwave power, irradiation time, and solvent to solid ratio were assessed in single-factor tests. Under optimal extraction conditions (48.86% ethanol, 626.53 W microwave power, 99.48 s irradiation, 29.67 mL/g solvent to solid ratio and 21.12 W/mL power density), TPC was 58.45 ± 0.68 mg GAE/g DW, close to the predicted 59.78 ± 1.47 mg GAE/g DW. The MAE method outperformed maceration extraction (8.41 ± 0.25 mg GAE/g DW) and decoction extraction (38.74 ± 0.81 mg GAE/g DW) in terms of extraction time, solvent use, and efficiency. The optimised extract exhibited significant antioxidant activity with IC50 values of 0.294 ± 0.004 mg/mL (DPPH) and 0.425 ± 0.005 mg/mL (ABTS), confirming the efficacy of MAE in preparing antioxidant-rich plant extracts.

n-Butanol fraction of moringa seed attenuates arsenic intoxication by regulating the uterine inflammatory and apoptotic pathways.

The adverse effects of arsenic-chelating drugs make it essential to replace invasive chelating therapy with non-invasive oral therapy for arsenic poisoning. The goal of the current investigation was to determine whether the uterine damage caused by arsenization could be repaired by the n-butanol fraction of Moringa oleifera seed (NB). The rats were orally administered with arsenic (10 mg/kg BW) for the initial 8 days, followed by NB (50 mg/kg) for the next 8 days without arsenic. The probable existence of different components in NB was evaluated by HPLC-MS. Pro and anti-inflammatory indicators were assessed by RT-PCR and western blot. ESR-α was detected via immunostaining. Arsenic-exposed rats had significantly increased lipid peroxidation and decreased antioxidant enzyme activity, which were markedly reduced after NB treatment. Weaker ESR-α expression and distorted uterine histomorphology following arsenication were retrieved significantly by NB. Meaningful restoration by NB was also achieved for altered mRNA and protein expression of various inflammatory and apoptotic indicators. Molecular interaction predicted that glucomoringin and methyl glucosinolate of moringa interact with the catalytic site of caspase-3 in a way that limits its activity. However, NB was successful in restoring the arsenic-mediated uterine hypofunction. The glucomoringin and methyl glucosinolate present in n-butanol fraction may play a critical role in limiting apoptotic event in the arsenicated uterus.

Supplementation with Moringa oleifera Lam leaf and seed flour during the pregnancy and lactation period of Wistar rats: Maternal evaluation of initial and adult neurobehavioral development of the rat progeny.

ETHNOPHARMACOLOGICAL RELEVANCE: Moringa oleifera Lam. (M. oleifera) is a tree species of Indian origin popularly known as the "tree of life". In various cultures, it is used by pregnant women to increase milk production, yet studies on its effects during pregnancy and lactation are lacking. AIM OF THE STUDY: To evaluate the nutraceutical aspects of flours produced from the leaves and seeds of M. oleifera, and to evaluate the effect of supplementation of pregnant Wistar rats during the gestation and lactation period, with the aim of studying the weight gain and neonatal parameters of the pregnant rats, as well as effects on the neurobehavioral development and memory in their offspring. MATERIALS AND METHODS: The flour supplementation was conducted at a concentration of 100 mg per kg of animal body weight. For the memory tests, the Open Field Habituation test was performed and repeated after seven days. The Object Recognition test was conducted with the animal exposed to the open field in short and long familiarization sessions. The data obtained were analyzed using Kruskal-Wallis tests for non-parametric data and one-way and two-way ANOVA for parametric data. RESULTS: Flour produced from both the leaf and seed of M. oleifera was found to contain significant amounts of nutrients (protein, fibre, carbohydrates, etc.), making them suitable for supplementation. The exposure of pregnant rats to M. oleifera leaf and seed flours did not affect weight gain, did not have harmful effects on the birth of offspring, and did not result in abortions or mutations in the offspring. Regarding the supplemented group's offspring, early maturation of the senses in the offspring compared to the control group was observed in all tests were conducted; indicating that supplementation positively impacted cognitive development. Further, the offspring of the supplemented rats presented reduced locomotion and greater exploration of new objects compared to the control group offspring, indicating positive effects on learning. CONCLUSION: This study describes for the first time the beneficial effects on pregnant Wistar rats and their offspring of maternal supplementation with flour products from the leaves and seeds of M. oleifera.

Effects of dietary Moringa oleifera leaf extract on semen characteristics, fertility, and hatchability in aged broiler breeder roosters.

Declining semen quality will have a negative impact on the fertility of aged roosters. Various factors influence this decrease in quality. This study was conducted to investigate the effects of different levels of Moringa plant extract on semen characteristics, fertility, and hatchability in aged broiler breeder roosters. A total of 24 roosters were fed 1 of 4 dietary supplements for 10 wk: Control, 100 µL/kg (Moringa oleifera leaf extract [MOLE]-100), 200 µL/kg (MOLE-200), or 400 µL/kg body weight (MOLE-400) of Moringa oleifera extract. Results showed supplementation with MOLE-200 significantly improved (P < 0.05) semen concentration, total motility, progressive motility, sperm membrane integrity compared to other treatments. However, semen volume and body weight were unaffected (P > 0.05). Sperm lipid peroxidation, as indicated by malondialdehyde concentration, was lowest in MOLE-200. There was a significant difference observed among the treatments in terms of total antioxidant capacity (TAC) results. The testosterone concentration in the MOLE-200 treatment was significantly higher than the other treatments (P < 0.05). However, no significant differences were observed in the levels of luteinizing hormone (LH) and follicle-stimulating hormone (FSH) hormones among the experimental treatments. Fertility and hatchability rates were measured at the end of the trial. Fertility, defined as the number of fertilized eggs, was greatest in the MOLE-200 treatment compared to the other treatments. Similarly, hatchability (hatched chicks/fertilized eggs %) was highest at 88.02% for MOLE-200. In conclusion, dietary supplementation with M. oleifera extract improved semen quality, fertility, and hatchability in aged broiler breeder roosters.

Antimicrobial and Synergistic Effects of Syzygium cumini, Moringa oleifera, and Tinospora cordifolia Against Different Candida Infections.

Introduction The burden of multiple drug resistance in human pathogens has necessitated the search for and development of antimicrobial agents with a wide range of structural classes and potentials to selectively act on the several mechanisms of actions exhibited by the pathogens. However, most synthetic antimicrobial agents have been linked with adverse side effects and high costs, furthering the need to explore more options. Syzygium cumini, Moringa oleifera, and Tinospora cordifolia are three medicinal plants used in traditional medicine systems for various infectious diseases. They contain various phytochemicals that exhibit antimicrobial activities against various bacteria, fungi, and parasites. The mechanisms of their antimicrobial action may involve the disruption of microbial cell walls and membranes, the inhibition of microbial enzyme and biofilm formation, the modulation of microbial gene expression and quorum sensing, and the induction of microbial cell death. Therefore, the present study evaluated the potentials of aqueous and ethanol extracts of S. cumini, M. oleifera, and T. cordifolia in managing infections as measured by their inhibitory effects on species. Materials and method Syzygium cumini, M. oleifera, and T. cordifolia were obtained and authenticated, and their aqueous and ethanol extracts were prepared. The antibacterial properties of the aqueous and ethanol extracts were examined. In addition to broth microdilution and biofilm development experiments, we also employed disk diffusion and agar-well diffusion techniques. The inocula of various species, including krusei, parapsilosis, utilis, albicans, and glabrata, were prepared for these assays. The synergistic effect of plant extracts with fluconazole was also evaluated. Results Syzygium cumini, M. oleifera, and T. cordifolia emerge as promising sources for the development of effective and sustainable antimicrobial interventions. Interestingly, the aqueous and ethanol extracts were effective against the selected species. Also, the synergistic combination of plant extracts with fluconazole was observed to triple the potency of the extracts. Furthermore, the potency of the plant extract as an antifungal and synergistic agent was ranked as S. cumini > M. oleifera > T. cordifolia. Conclusively, the plant extracts are effective in the management of opportunistic fungal infections.

Fortified chocolate mousse with powder and extract from Moringa oleifera leaves for nutritional value improvement.

This study focuses on the characterisation and incorporation of Moringa oleifera leaf powder (MOP) from Luanda (Angola) and its extract (MOE) in fortified chocolate mousse. Dark green (DG) leaves presented superior nutritional values compared to other leaves. DG contained a higher concentration of mineral salts (10 ± 1 mg/100 g of dry leaves), phenolic compounds (267 ± 4 mg GAE/g), vitamins (1.9 ± 0.2 mg/g of dry extract) and strong antioxidant capacity (IC50, 115 ± 8 µg/mL). Therefore, DG leaves were used to fortify the chocolate mousse. The leaves were prepared in three samples: control, 2 % MOP (w/w) and 2 % MOE (v/v). Textural and rheological analysis of chocolate mousse samples revealed a pseudoplastic profile for all samples, with decreased texture attributes and viscosity due to the incorporation. The sensory evaluation demonstrated that MOP and MOE samples presented 93 % and 88 % resemblance to the original product regarding general acceptance, respectively.

Impact of Fermentation on the Phytochemical Content and Biological Properties of Moringa oleifera Lam. Shoot Teas.

This work examined the variation in chemical and biological properties of Moringa oleifera Lam. shoot (MOS) teas prepared under different degrees of fermentation, viz: non-fermented, semi-fermented and fermented. The chemical composition was ascertained via FTIR, GC-MS, total phenolic and total flavonoid content. Also determined were the biological properties, including antioxidant, antimicrobial and alpha-amylase inhibitory activities. The data confirmed that MOS teas were rich in phenolic and flavonoid compounds, with fermented MOS tea displaying the highest phenolic and flavonoid contents. With respect to antioxidant property, all tea extracts exhibited good radical scavenging activities against DPPH⋅, ABTS⋅+ and NO⋅, and the radical scavenging capacity was in the order of non-fermented>semi-fermented>fermented MOS teas. The same trend was also observed for the antimicrobial activities against Staphylococcus aureus and Staphylococcus epidermidis. In contrast, the fermented MOS tea exhibited better α-amylase inhibitory activity compared to the non-fermented and semi-fermented MOS teas.

Moringa oleifera leaves extract loaded gold nanoparticles offers a promising approach in protecting against experimental nephrotoxicity.

Cisplatin is one of the most important antitumor drugs, however; it has numerous adverse effects like nephrotoxicity which is considered one of cisplatin uses . The study was planned to evaluate the nephroprotective effect of M. oleifera leaves extract loaded gold nanoparticles (Au-NPs) against cisplatin-induced nephrotoxicity in rats. Initially, total phenolic contents (TPC) and the antioxidant activity of the M. oleifera leaves extract were evaluated and recorded 8.50 mg/g and 39.89 % respectively. After that, the dry leaves of M. oleifera were grinded into fine powder and extracted using water extraction system. Then, different volumes (0.5, 1 and 2 mL) of M. Oleifera were blended with constant volume of Au-NPs (1 mL). Both Au-NPs and M. oleifera extract loaded Au-NPs were investigated using transmission electron microscope (TEM) that illustrated the deposition of M. Oleifera onto Au-NPs. The experimental study was performed on seventy male albino rats alienated into seven groups. Group I healthy rats, group II injected with one dose of cisplatin (CisPt), groups from III to VII treated groups received CisPt then received M. Oleifera leaves extract alone and /or Au-NPs with different ratios and concentrations. After the experiment' time, serum urea and creatinine, kidney injury molecule-1 (KIM-1), advanced oxidation protein products (AOPP), monocyte chemoattractant protein-1 (MCP-1), tumor necrotic factor-α (TNF-α), and interleukin-6 (IL-6) were evaluated as markers of renal nephrotoxicity. The kidneys of rats were excised for malondialdehyde (MDA), nitric oxide (NO), and superoxide dismutase (SOD) assessments. Induction of CisPt showed a highly significant disturbance in oxidant/anti-oxidant balance and inducing inflammatory cascades supporting nephrotoxicity, while treatment with M. Oleifera leaves extract, Au-NPs, and the different concentrations of the extract loaded on Au-NPs had a crucial role in attenuating oxidative stress, enhancing antioxidant systems, and reducing inflammatory biomarkers, although the most significant results showed a powerful scavenging activity against nephrotoxicity induced by CisPt was obtained with M. Oleifera leaves extract loaded on Au-NPs with a concentration of 2:1 respectively.

Pathological effects of feeding aflatoxin-contaminated feed on immune status and reproductive performance of juvenile white leghorn males and its mitigation with ∝-tocopherol and Moringa oleifera.

This study was planned to detect the adverse pathological consequences of aflatoxin B1 in White Leghorn (WLH) layer breeder males. Eight-week-old male layer cockerels were separated into six experimental categories: A group was kept as negative control, offered with normal feed only; group B was fed with 400 ppb amount of aflatoxin, while groups F and D fed with normal feed and supplemented with vitamin E 100 ppm and 1% Moringa oleifera, respectively, whereas groups E and C were fed with 400 ppb aflatoxin containing feed and ameliorated with vitamin E 100 ppm and 1% Moringa oleifera, respectively. This study was continued for 2 months and immunologic disorders and reproductive parameters were observed during the trial. To find out immunological status lymphoproliferative response to phytohemagglutinin-P (PHA-P), antibody titers against sheep red blood cells (SRBCs) and carbon clear assay were performed by collecting samples from five birds from each group. The whole data was measured by ANOVA test, and group means were compared by DMR test by using M-Stat C software. Regarding the reproductive status, spermatogenesis, blood testosterone level, testes weight, testes histology, sperm motility, and morphology were negatively affected by aflatoxins, but these deviations positively ameliorated by vitamin E and Moringa. Vitamin E and Moringa found advantageous in boosting the immune status of affected bird. All the immunological parameters including antibody titers against sheed red blood cells, lymphoproliferative response to avian tuberculin and phagocytic potential of macrophages were suppressed by AFB1 however in control, Moringa and vitamin E groups these immunological responses were significantly higher.

Flavonoid from Moringa oleifera leaves revisited: A review article on in vitro, in vivo, and in silico studies of antidiabetic insulin-resistant activity.

Diabetes mellitus (DM) occurs when the body experiences insulin deficiency or is unable to use insulin appropriately, which increases the blood glucose levels over the threshold. Moringa oleifera leaf is a widely used and scientifically proven herbal medicine to treat DM. The demand for the development of new drugs has prompted in vitro, in vivo, and in silico studies of antidiabetic insulin-resistant activity. This study aims to conduct a comprehensive study of the types of flavonoid and nonflavonoid compounds that have antidiabetic activity in insulin resistance mellitus using in vitro, in vivo, and in silico approaches. The literature review was conducted in accordance with the offered reporting items for systematic review. Major bibliographic databases, i.e. Scopus, PubMed, and DOAJ, covering original articles about the aforementioned issues between January 1, 2011 and December 31, 2021 were used. In this study, 274 articles were retrieved, of which 4 were duplicates, and after the titles were read, only 108 were left for analysis. After the abstract screening, 32 articles were eligible for the literature review. The results exhibit that flavonoids, including quercetin and kaempferol, and nonflavonoids, including anthraquinone, cytogluside (glycoside), hemlock tannin, phenolic steroid, and 2-phenylchromenylium (anthocyanins), have potential insulin-resistant antidiabetic activity in vitro, in vivo, and in silico. This has broadened the research into the development of new drugs.

[Comparative study of purgative pharmacological effects and mechanisms of Moringa oleifera leaves and Rhei Radix et Rhizoma].

Moringa oleifera leaves are known for their "Virechana"(purgative) effect in Ayurvedic medicine in India. This study compared the purgative effects and mechanisms of M. oleifera leaves with the reference Rhei Radix et Rhizoma to establish a foundation for the further application of M. oleifera leaves in traditional Chinese medicine(TCM). Using network pharmacology and molecular docking methods, this study identified the material basis, common targets, and signaling pathways through which Rhei Radix et Rhizoma and M. oleifera leaves exerted their purgative pharmacological effects. A low-fiber diet-induced constipation mouse model was established to measure fecal parameters and small intestinal propulsion rate, and histological changes in the colon were observed using HE staining. Relative expression levels of relevant genes and target proteins were assessed using RT-qPCR and immunohistochemistry, respectively. The results showed that mapping the targets of Rhei Radix et Rhizoma and M. oleifera leaves onto the biological process network of constipation revealed close proximity, indicating that they may exert their therapeutic effects on constipation through similar biological processes. Molecular docking results indicated that compounds such as sennoside C and isoquercitrin could target serine/threonine protein kinases(AKT1) and mitogen-activated protein kinase 3(MAPK3), thereby affecting MAPK and calcium signaling pathways to promote defecation. Animal experiments demonstrated that both M. oleifera leaves and Rhei Radix et Rhizoma increased the number of fecal pellets and water content in constipated mice, improved small intestine motility, colon mucosal thickness, and muscle layer thickness, upregulated the gene expression levels of AKT1 and MAPK3 in the colon, and downregulated the expression of AQP3 protein. These findings suggest that M. oleifera leaves and Rhei Radix et Rhizoma share similarities in their therapeutic efficacy and mechanisms for treating constipation. Using Rhei Radix et Rhizoma as a reference can provide a better understanding of the characteristics of the "Virechana"(purgative) effect of M. oleifera leaves in TCM.

Assessment of hepatoprotective, nephroprotective efficacy, and antioxidative potential of Moringa oleifera leaf powder and ethanolic extract against PCOS-induced female albino mice (Mus Musculus).

Moringa oleifera is a medicinal plant that has anti-inflammatory, antihypertensive, antidiabetic, tissue-protective, and antioxidant activities. Here, we evaluated the protective effect of M. oleifera leaf powder (MoLP) and 70% ethanol M. oleifera leaf extract (MoLE) on mitigating polycystic ovary syndrome (PCOS)-induced liver and kidney dysfunction via regulating oxidative stress in female albino mice (Mus musculus). The efficacy of M. oleifera was compared with metformin (standard medicine used to treat infertility in women). PCOS was induced by intramuscular injection of testosterone enanthate at 1.0 mg/100 g BW for 35 days. PCOS-induced mice were treated with MoLP (250 and 500 mg/Kg), MoLE (250 and 500 mg/kg), and metformin (250 mg/kg) orally for 14 days. Renal function test (RFT), liver function test (LFT), and oxidative stress biomarker malondialdehyde (MDA) were quantified in serum at 0, 7, and 14 days of intervention. Mice treated with M. oleifera and metformin showed a significant decrease (p < .001) in alanine aminotransferase (ALT), aspartate aminotransferase (AST), alkaline phosphate (ALP), total bilirubin, urea, creatinine, and a significant increase (p < .001) in total protein, albumin, globulin, and albumin/globulin (A/G) ratio. Oxidative stress decreased significantly (p = .00) with respect to treatments, exposure days, and their interaction in metformin and all M. oleifera-treated groups. M. oleifera leaf powder and extract reduce oxidative stress and enhance nephron-hepatic activity in PCOS-induced female albino mice.
