“…The MLE enhancement effects on growth (number of leaves and branches, and arial part dry weight), yield (no. of capitula), and carotenoid contents observed in S. marianum plants grown under high salinity (4000 ppm) in the present investigation conformed to previous reports on numerous plant species grown under salinity [34][35][36][37] and other stresses [15,36,[38][39][40]. Besides the above parameters, MLE foliar spray also reduced the accumulation of Na + ions while increasing K + ions in the cells of plants irrigated with 4000 ppm saline.…”

Silybin A and B are two major hepatoprotective flavonolignans produced predominantly in Silybum marianum fruits. Similar to other plant secondary metabolites, silybin production is enhanced by biotic or abiotic stresses under the expanse of plant growth and yield. In this study, a novel strategy for enhancing silybin production was investigated by applying a natural plant growth enhancer, moringa leaf extract (MLE), to the S. marianum plants cultivated under salinity abiotic stress. The experiment was conducted using a split-plot design with salinity as the main factor and MLE concentrations as the sub-factor. The individual and combined effects of salinity and MLE on the growth, yield, and silybin content of S. marianum were recorded. The MLE at concentrations of 5 g/L or 10 g/L was applied as foliar spray to S. marianum plants, which were irrigated with either tap water or saline (2000 ppm or 4000 ppm). Our results revealed that 10 g/L MLE effectively enhances the growth, yield, and silybin (A + B) content in S. marianum plants not exposed to salinity stress. On the other hand, for plants that were exposed to 4000 ppm salinity, the application of MLE was able to alleviate the salinity-induced adverse effects on some of the plant growth parameters but did not significantly increase their silybin (A + B) compositions. The current study also indicated that the increase in silybin contents was accompanied by the upregulation of the chalcone synthase 1 and 3 genes, which have been implicated in the synthesis of silybin.

“…Thus, the overaccumulation of plant secondary metabolite acts as a plant adaptive mechanism in response to Cd stress (Ashraf et al 2018). These results are in harmony with that of Howladar (2014) and Khalofah et al (2020) who indicated that foliar application with moringa leaf extract significantly augmented the content of total phenols and the antioxidant potential in shoots of Phaseolus vulgaris and Lepidium sativum plants when compared to plants grown under Cd stress.…”

Purpose The use of plant extracts obtained from plants that are highly tolerant to heavy metal toxicity has been beneficial in improving the growth of plants grown under metal toxicity conditions. A lab experiment was performed to elucidate the alleviating role of foliar applied cadmium (Cd)-hyperaccumulator Solanum nigrum (S. nigrum) extract on Datura innoxia (D. innoxia) plants grown under Cd stress (0, 50, and 100 mg Cd kg-1 soil). Methods Growth parameters, photosynthetic pigment content, osmo-metabolic compounds, reduced glutathione and phytochelatins content, oxidative damage, and lignin content and its related enzyme (cell wall-bound peroxidase, POX) were determined. Results Apart from the foliar application response of S. nigrum leaf extract (SNE) in either Cd exposed or non-Cd exposed plants, growth parameters of D. innoxia plant grown under both Cd concentrations (50 and 100 mg Cd kg-1 soil) in terms of root and shoot fresh, dry weight, length, and leaf area were noticeably diminished by 29 and 51%, 29 and 54%, 35 and 70%, 40 and 53%, 30 and 69%, 40 and 60%, and 11 and 23%, respectively, compared with untreated control plants. Foliar delivered SNE secured the photosynthetic pigment, free amino acids, soluble proteins, and soluble sugar content. Additionally, it lessened the adverse effects of Cd stress on D. innoxia plants by curtailing the content of hydrogen peroxide (H2O2) and malondialdehyde (MDA) by 28 and 27%, and 21 and 23%, respectively, compared with the plants subjected to 50 and 100 mg Cd kg-1 only. The findings herein indicated that the plant water extract and their interactions in the investigated Cd rates significantly augmented phenolics, alkaloids, reduced glutathione and phytochelatins content. Cell wall stiffening in D. innoxia indicated that lignin content and POX were significantly higher in plants exposed to 100 mg Cd kg-1 soil displaying increase values of 275 and 300%, respectively, against non-Cd treated control. The magnitude of increment imposed by Cd stress was lessened by using SNE that reflects on adequate cell growth advocated by limited lignification, in terms of lignin content, and downregulated POX activity. Owing to SNE application, root and leaves Cd contents were efficiently reduced reflecting apparent plant liveliness compared with the SNE non-treated Cd-stressed plants. Conclusions The outcomes of this study designate that foliar application of the Cd-hyperaccumulator S. nigrum leaf extract can be counted as an unconventional and innovative approach in the alleviation of Cd stress and can be employed as integrated practice when Cd-contaminated regions were exploited for sustainable agriculture of the multipurpose plants.

“…Moringa oleifera tea with antioxidant potential (81% inhibition of DPPH radicals compared with vitamin-C (0.1 mg/mL) with 76.5% inhibition) might be helpful in preventing stress-related chronic disorders [ 65 ]. Recently, Khalofah et al [ 66 ] studied that moringa leaf extract significantly reduced the negative effect of cadmium stress on Lepidium sativum . A moringa extract dosage of 100 mg/kg body weight effectively increases the antioxidant levels in aluminum phosphide-intoxicated rats and reduces malondialdehyde (MDA).…”

Based on the availability of many nutrients, Moringa oleifera tree leaves have been widely employed as nutrients and nutraceuticals in recent years. The leaves contain a small amount of anti-nutritional factors and are abundant in innumerable bioactive compounds. Recently, in several in vivo and in vitro investigations, moringa leaves’ bioactive components and functionality are highlighted. Moringa leaves provide several health advantages, including anti-diabetic, antibacterial, anti-cancer, and anti-inflammatory properties. The high content of phytochemicals, carotenoids, and glucosinolates is responsible for the majority of these activities as reported in the literature. Furthermore, there is growing interest in using moringa as a value-added ingredient in the development of functional foods. Despite substantial study into identifying and measuring these beneficial components from moringa leaves, bioaccessibility and bioavailability studies are lacking. This review emphasizes recent scientific evidence on the dietary and bioactive profiles of moringa leaves, bioavailability, health benefits, and applications in various food products. This study highlights new scientific data on the moringa leaves containing nutrient and bioactive profiles, bioavailability, health benefits, and uses in various food items. Moringa has been extensively used as a health-promoting food additive because of its potent protection against various diseases and the widespread presence of environmental toxins. More research is needed for utilization as well as to study medicinal effects and bioaccesibility of these leaves for development of various drugs and functional foods.
