Abstract
Moringa oleifera is an important medicinal plant in several countries; for example, Nigeria, the USA, Turkey, Germany, Greece, and Ukraine. The abundant bioactive and nutritional properties of this plant make it useful in many and diverse areas of life, including the health, cosmetic, agricultural, and food industries to mention but a few. Research has found that the presence of proteins, carbohydrates, lipids, vitamins, minerals, flavonoids, phenols, alkaloids, fatty acids, saponins, essential oils, folate, aromatic hydrocarbons, sterols, glucosinolates, and glycosides, among others, characterize the moringa nutrient profile and, as a result, give rise to its remedial effects on ailments such as wounds, stomach and duodenal ulcers, allergies, obesity, diabetes, inflammation, asthma, and so on. It is the aim of this review to provide an insight into such medicinal and pharmacological remedies attributed to moringa, stating both the past and recent discoveries. This review article also takes a look into the botanical features, bioactive compounds, antinutrients, food applications, bacterial fermentation products, biosafety, industrial applications, and other uses of moringa. Finally, with the belief that knowledge is progressive, we acknowledge that there are things yet undiscovered about this wonder plant that will be of value both to medicine and general life; we therefore recommend that research work continues on the moringa plant. © 2023 Society of Chemical Industry.

Abstract
The liver and the kidney are one of the vital organs of body. Drug-induced toxicity is one of the most common problems encountered by these organs. The search for an effective medicine to treat this toxicity without any side effects has led to the use of traditional-based medicine. This study evaluated the effect of ethanolic extract of Moringa oleifera seed oil on hepatic and renal markers in dimethyl 2, 2-dichlorovinyl phosphate (DDVP, known as dichlorvos)-exposed Wistar rats. Twenty-one male Wistar rats were randomly divided into three groups of seven animals each. Group A served as the negative control and were not exposed to dichlorvos. Group B served as the positive control and were exposed to dichlorvos for 2 minutes but received no extract. Group C animals were exposed to the dichlorvos and received 300mg/kg of extract (Moringa oleifera seed oil) for 7days before and 21days after exposure. Exposure to DDVP led to a significant increase in hepatic & renal markers, inflammatory markers, decrease in plasma protein and alteration of plasma electrolyte. Moringa oleifera seed oil regulated and significantly enhanced plasma protein, reduced elevated levels of hepatic & renal markers, inflammatory markers in the study sample. In addition, histopathology observation showed that Moringa seed oil was able to regenerate the hepatorenal damage on exposure to dichlorvos. Conclusion: Moringa oleifera seed oil exhibited hepato-protective, nephroprotective properties and could be explored in nutrition and health.

Abstract
The genus Moringa Adans. comprises 13 species, of which Moringa oleifera Lam. native to India and cultivated across the world owing to its drought and frost resistance habit is widely used in traditional phytomedicine and as rich source of essential nutrients. Wide spectrum of phytochemical ingredients among leaf, flower, fruit, seed, seed oil, bark, and root depend on cultivar, season, and locality. The scientific studies provide insights on the use of M. oleifera with different aqueous, hydroalcoholic, alcoholic, and other organic solvent preparations of different parts for therapeutic activities, that is, antibiocidal, antitumor, antioxidant, anti-inflammatory, cardio-protective, hepato-protective, neuro-protective, tissue-protective, and other biological activities with a high degree of safety. A wide variety of alkaloid and sterol, polyphenols and phenolic acids, fatty acids, flavanoids and flavanol glycosides, glucosinolate and isothiocyanate, terpene, anthocyanins etc. are believed to be responsible for the pragmatic effects. Seeds are used with a view of low-cost biosorbent and coagulant agent for the removal of metals and microbial contamination from waste water. Thus, the present review explores the use of M. oleifera across disciplines for its prominent bioactive ingredients, nutraceutical, therapeutic uses and deals with agricultural, veterinarian, biosorbent, coagulation, biodiesel, and other industrial properties of this "Miracle Tree."

Abstract
Moringa oleifera is a natural plant with high nutritional and pharmacological value. Leaves of M. oleifera contain a variety of active substances. In our previous research, we had obtained a polysaccharide separated from M. oleifera leaf, namely MOs-2-a (1.35 × 104 Da). In this study, this polysaccharide was administrated daily to 6 week-old ICR mice for 4 weeks. Then, the body weight, immunity, intestinal digestion, and intestinal microenvironment of Institute of Cancer Research (ICR) mice were investigated. After 4 weeks of feeding intervention with the polysaccharide, the immune and intestinal digestive ability of the ICR mice were significant as shown by the organ index, digestive enzymes, and reduction of serum tumor necrosis factor-alpha and diamine oxidase levels. The polysaccharide could regulate the microbial composition of the intestinal tract in mice by increasing the bacteria that have been reported for antiobesity effects, short chain fatty acid production, and lactic acid production. These findings indicate that the polysaccharide of M. oleifera leaf might be a promising prebiotic that exhibits health promotion effects.

Abstract
The present study was performed to determine the effect of Moringa oleifera fruit extract on the apoptosis of human melanoma A2058 cells. A2058 cells were treated for 72 h with Moringa oleifera fruit extract at 50-100 µg/ml, and cell viability with apoptotic changes was examined. The involvement of reactive oxygen species (ROS) and mitogen-activated protein kinases (MAPKs) was examined. It was revealed that Moringa oleifera fruit extract significantly inhibited the cell viability and promoted apoptosis of A2058 cells in a concentration-dependent manner. Moringa oleifera fruit extract-treated A2058 cells exhibited increased activities of cleaved caspase-9 and caspase-3. It also caused an enhancement of MAPK phosphorylation and ROS production. The pro-apoptotic activity of Moringa oleifera fruit extract was significantly reversed by pretreatment with the c-Jun N-terminal kinase (JNK) inhibitor SP600125, extracellular-signal-regulated kinase (ERK) inhibitor PD98058 or ROS inhibitor N-acetyl-L-cysteine. Taken together, Moringa oleifera fruit extract is effective in inducing mitochondrial apoptosis of A2058 cells, which is mediated through induction of ROS formation, and JNK and ERK activation. Moringa oleifera fruit extract may thus have therapeutic benefits for human melanoma A2058 cells.

Abstract
Background. The Moringa oleifera plant has been implicated for several therapeutic potentials. Objective. To evaluate whether addition of M. oleifera to diet has protective effect against nickel-induced nephrotoxicity in rats. Methodology. Male Wistar rats were assigned into six groups of five. The rats were given oral exposure to 20 mg/kg nickel sulphate (NiSO4) in normal saline and sustained on either normal diet or diets supplemented with Moringa oleifera at different concentrations for 21 days. 24 hours after cessation of treatments, all animals were sacrificed under slight anesthesia. The blood and kidney samples were collected for biochemical and histopathology analyses, respectively. Results. NiSO4 exposure reduced the kidney-to-body weight ratio in rats and caused significant elevation in the levels of plasma creatinine, urea, and potassium. Also, the plasma level of sodium was decreased by NiSO4 exposure. However, addition of M. oleifera to diets averted the nickel-induced alteration to the level of creatinine and urea. The histopathology revealed damaged renal tubules and glomerular walls caused by NiSO4 exposure. In contrast, the damages were ameliorated by the M. oleifera supplemented diets. Conclusion. The addition of M. oleifera to diet afforded significant protection against nickel-induced nephrotoxicity.

Abstract
In the present study, the efficacy of β-sitosterol isolated from an n-butanol extract of the seeds of the plant Moringa oleifera (Moringaceae) was examined against ovalbumin-induced airway inflammation in guinea pigs. All animals (except group I) were sensitized subcutaneously and challenged with aerosolized 0.5% ovalbumin. The test drugs, β-sitosterol (2.5mg/kg) or dexamethasone (2.5mg/kg), were administered to the animals (p.o.) prior to challenge with ovalbumin. During the experimental period (on days 18, 21, 24 and 29), a bronchoconstriction test (0.25% acetylcholine for 30s) was performed and lung function parameters (tidal volume and respiration rate) were measured for each animal. On day 30, blood and bronchoalveolar lavaged fluid were collected to assess cellular content, and serum was collected for cytokine assays. Lung tissue was utilized for a histamine assay and for histopathology. β-sitosterol significantly increased the tidal volume (V(t)) and decreased the respiration rate (f) of sensitized and challenged guinea pigs to the level of non-sensitized control guinea pigs and lowered both the total and differential cell counts, particularly eosinophils and neutrophils, in blood and bronchoalveolar lavaged fluid. Furthermore, β-sitosterol treatment suppressed the increase in cytokine levels (TNFα, IL-4 and IL-5), with the exception of IL-6, in serum and in bronchoalveolar lavaged fluid detected in model control animals. Moreover, treatment with β-sitosterol protected against airway inflammation in lung tissue histopathology. β-sitosterol possesses anti-asthmatic actions that might be mediated by inhibiting the cellular responses and subsequent release/synthesis of Th2 cytokines. This compound may have therapeutic potential in allergic asthma.

Abstract
Moringaceae, which belongs to the Moringa oleifera Lam. family, is a well-known herb used in Asian medicine as an antiallergic drug. In the present study, the efficacy of the n-butanol extract of the seeds of the plant (MONB) is examined against ovalbumin-induced airway inflammation in guinea pigs. The test drugs (MONB or dexamethasone) are administered orally prior to challenge with aerosolized 0.5% ovalbumin. During the experimental period, bronchoconstriction tests are performed, and lung function parameters are measured. The blood and bronchoalveolar lavage fluid are collected to assess cellular content, and serum is used for cytokine (tumor necrosis factor-alpha, interleukin-4, and interleukin-6) assays. Histamine assays of lung tissue are performed using lung tissue homogenate. The results suggest that in ovalbumin-sensitized model control animals, tidal volume is decreased, respiration rate is increased, and both the total and differential cell counts in blood and bronchoalveolar lavage fluid are increased significantly compared with nonsensitized controls. MONB treatment shows improvement in all parameters except bronchoalveolar lavage tumor necrosis factor-alpha and interleukin-4. Moreover, MONB treatment demonstrates protection against acetylcholine-induced bronchoconstriction and airway inflammation. These results indicate that MONB has an inhibitory effect on airway inflammation. Thus, MONB possesses an antiasthmatic property through modulation of the relationship between Th1/Th2 cytokine imbalances.

Abstract
This study was carried out to evaluate the effect of Moringa oleifera Lam (Moringa) seed extract on liver fibrosis. Liver fibrosis was induced by the oral administration of 20% carbon tetrachloride (CCl(4)), twice weekly and for 8 weeks. Simultaneously, M.oleifera Lam seed extract (1g/kg) was orally administered daily. The biochemical and histological results showed that Moringa reduced liver damage as well as symptoms of liver fibrosis. The administration of Moringa seed extract decreased the CCl(4)-induced elevation of serum aminotransferase activities and globulin level. The elevations of hepatic hydroxyproline content and myeloperoxidase activity were also reduced by Moringa treatment. Furthermore, the immunohistochemical study showed that Moringa markedly reduced the numbers of smooth muscle alpha-actin-positive cells and the accumulation of collagens I and III in liver. Moringa seed extract showed significant inhibitory effect on 1,1-diphenyl-2-picrylhydrazyl free radical, as well as strong reducing antioxidant power. The activity of superoxide dismutase as well as the content of both malondialdehyde and protein carbonyl, which are oxidative stress markers, were reversed after treatment with Moringa. Finally, these results suggested that Moringa seed extract can act against CCl(4)-induced liver injury and fibrosis in rats by a mechanism related to its antioxidant properties, anti-inflammatory effect and its ability to attenuate the hepatic stellate cells activation.
