ABSTRACT

Moringa seeds are an excellent dietary source of phytochemicals (i.e., glucosinolates, GSLs; isothiocyanates, ITCs) with health-beneficial effects. Although numerous studies have been conducted on moringa seeds, the effect of germination on the regulation of GSLs remains scarcely explored. The present study investigated the dynamic changes of GSLs in moringa seeds during germination (at 25, 30, and 35 °C for 6 days in the dark) through an untargeted metabolomics approach and compared the antioxidant capacity of ungerminated and germinated moringa seeds. Our results showed that germination significantly increased the total GSL content from 150 (day 0) to 323 µmol/g (35 °C, day 6) on a dry weight (DW) basis, especially glucomoringin (GMG), the unique glucosinolate in moringa seeds, which was significantly upregulated from 61 (day 0) to 149 µmol/g DW (35 °C, day 4). The upregulation of GMG corresponded to the metabolism of tyrosine, which might be the initial precursor for the formation of GMG. In addition, germination enhanced the total ITC content from 85 (day 0) to 239 µmol SE/g DW (35 °C, day 6), indicating that germination may have also increased the activity of myrosinase. Furthermore, germination remarkably increased the total phenolic content (109-507 mg GAE/100 g DW) and antioxidant capacity of moringa seeds. Our findings suggest that moringa sprouts could be promoted as a novel food and/or ingredient rich in GMG.

ABSTRACT

Introduction: The synthesis of nanoparticles using naturally occurring reagents such as vitamins, sugars, plant extracts, biodegradable polymers and microorganisms as reductants and capping agents could be considered attractive for nanotechnology. These syntheses have led to the fabrication of limited number of inorganic nanoparticles. Among the reagents mentioned above, plant-based materials seem to be the best candidates, and they are suitable for large-scale biosynthesis of nanoparticles. Methods: The aqueous extract of Moringa peregrina leaves was used to synthesize silver nanoparticles. The synthesized nanoparticles were characterized by various spectral studies including FT-IR, SEM, HR-TEM and XRD. In addition, the antioxidant activity of the silver nanoparticles was studied viz. DPPH, ABTS, hydroxyl radical scavenging, superoxide radical scavenging, nitric oxide scavenging potential and reducing power with varied concentrations. The anticancer potential of the nanoparticles was also studied against MCF-7 and Caco-2 cancer cell lines. Results: The results showed that silver nanoparticles displayed strong antioxidant activity compared with gallic acid. Furthermore, the anticancer potential of the nanoparticles against MCF-7 and Caco-2 in comparison with the standard Doxorubicin revealed that the silver nanoparticles produced significant toxic effects against the studied cancer cell lines with the IC50 values of 41.59 (Caco-2) and 26.93 (MCF-7) µg/mL. Conclusion: In conclusion, the biosynthesized nanoparticles using M. peregrina leaf aqueous extract as a reducing agent showed good antioxidant and anticancer potential on human cancer cells and can be used in biological applications.

ABSTRACT

Moringa stenopetala is considered a superfood due to the many bioactive compounds that it provides to the diet. However, like all edible plants, it is mandatory to guarantee food safety. Thus it is necessary to develop analytical methods that can rapidly and accurately determine hazardous pollutants, to evaluate compliance with food regulations. In this regard, two multi-component procedures were developed trying to cover some of the main organic and inorganic potential contaminants. A microwave-assisted digestion followed by electrothermal atomic absorption spectrometry was used for arsenic, cadmium, and lead determination, while a modification of the QuEChERS protocol followed by gas chromatography-tandem mass spectrometry was employed for the determination of 55 pesticides from different families. Both analytical methods were thoroughly validated according to international guidelines. The analyzed samples obtained from the Uruguayan market showed compliance with both, national and international, food regulations. The holistic approach employed in this research is not commonly presented in the literature, thus constituting a novel way to face food safety.

ABSTRACT

Corn starch (CS) is a good alternative to synthetic polymers due to its sustainability; nevertheless, because of its weak tensile strength, the matrix requires another polymer. Therefore, 0.5 % (w/v) moringa gum (MG) was added. The purpose of this study was to assess how pine cone extract (PCE) affected the physiochemical and mechanical properties of corn starch and moringa gum (CS/MG) films and their use as UV-blocking composites. The findings suggest that the PCE improved the elongation at break from 3.27 % to 35.2 % while greatly reducing the tensile strength. The hydrogen bonding between CS/MG and PCE was visible in the FTIR spectra. The XRD graph indicated that the films were amorphous. In comparison to CS/MG films, PCE-incorporated edible films demonstrated significant UV-blocking ability indicating their potential as sustainable packaging material for light-sensitive food products.

ABSTRACT

BACKGROUND: Moringa stenopetala leaves (Baker f.) Cufod. (Moringaceae) are used as a staple food and traditional medicine for treating various diseases like malaria, hypertension, stomach pain, diabetes, elevated cholesterol, and removing the retained placenta. Its prenatal toxicity study is minimal. Thus, this study aimed to assess the toxic effects of a 70% ethanol extract of Moringa stenopetala leaf on the fetuses and placentas of pregnant Wistar rats. METHOD: Fresh leaves of Moringa stenopetala were collected, dried at room temperature, ground to powder, and extracted using 70% ethanol. For this study, five groups of animals, each containing ten pregnant rats, were used. Groups I-III were experimental groups and treated with 250, 500, and 1000 mg/kg body weight of Moringa stenopetala leaf extract, respectively. Groups IV and V were pair-fed and ad libitum control groups. The extract was given during gestation days 6 to 12. The fetuses were recovered at day 20 of gestation and examined for the presence of developmental delays, gross external malformations, skeletal and visceral defects. Gross and histopathological changes in the placenta were also evaluated. RESULTS: Compared to the pair-fed control group, maternal daily food intake and weight gain were reduced in the 1000 mg/kg-treated group during the treatment and post-treatment periods. A significantly higher number of fetal resorptions was also seen in the 1000 mg/kg treatment group. The crown-rump length and fetal and placental weights were all significantly reduced in pregnant rats given 1000 mg/kg. However, there were no visible malformations in the visceral organs as well as external genitalia in all the treatment and control groups. About 40.7% of the fetuses in the 1000 mg/kg treated rats had no proximal hindlimb phalanges. In addition, light microscopic investigations of the placenta in the high-dose treated rats revealed structural changes in the decidual basalis, trophoblastic zone, and labyrinthine zones. CONCLUSION: In conclusion, consumption of M. stenopetala leaves at a higher dose may have toxic effects on the development of rat fetuses. At a higher dose, the plant extract increased the number of fetal resorptions, reduced the number of fetuses, decreased the fetal and placental weights, and alter the placental histopathology. Thus, it is recommended to limit the excess feeding of M. stenopetala leaves during gestation.

ABSTRACT

One of the major complications of diabetes mellitus (DM) is diabetic cardiomyopathy (DCM) due to the multifaceted therapy involved. Here, we evaluated the combinatorial effect of Moringa leaf (ML) and seed (MS) supplemented diets plus acarbose (ACA) on cardiac acetylcholinesterase (AChE), adenosine triphosphatase (ATPase), adenosine deaminase (ADA), monoamine oxidase (MAO), arginase, angiotensin-I converting enzyme (ACE), and lactate dehydrogenase (LDH) activities, thiobarbituric acid reactive species (TBARS), and thiols levels. The diets and ACA (25 mg/kg) were administered for 14 days. The fasting blood glucose level (FBGL), cardiac AChE, ATPase, ADA, MAO, arginase, ACE, LDH activities, and TBARS and thiol levels were determined. Relative to the normal rats, the biomarkers were significantly increased in DM rats but were suppressed significantly in the diets plus ACA-treated rats while improving antioxidant status, with the 4% Moringa plus ACA proving outstanding compared to individual ML/MS and ACA. In addition, ML-supplemented diets with/without ACA had better effects compared to MS with/without ACA, respectively. In conclusion, the combination of ML/MS supplemented diets and ACA synergistically modulates the tested biochemicals. However, the effect on blood vessels and the nerves that control the heart, stiffness of left ventricular (LV) hypertrophy, fibrosis, cell signaling abnormalities, related gene expression, clinical trials, and echocardiology studies should be further investigated to affirm this claim. PRACTICAL APPLICATIONS: Moringa oleifera has been a vocal appetite in mitigating cardiovascular disease induced by diabetes, but the formulation of a medicinal diet as an ameliorative route of attention to the pathology is fairly addressed, not talking of its combination with the synthetic antidiabetic drug, such as ACA. Based on this experiment, it is imperative to explore such an idea. This research shows that co-administration of moringa leaf/seed formulated diets plus ACA exhibits a synergistic effect in DCM management. However, further research is needed in this field of experiment.

ABSTRACT

INTRODUCTION: We investigated the effect of dietary inclusions of Moringa seed (5% and 10%) on blood pressure, angiotensin-1 converting enzyme (ACE) activity, and gene expression, as well as redox status in hypertensive rats. MATERIAL AND METHODS: Wistar strain albino rats were fed moringa seed-based diets for two weeks prior L-NAME (40 mg/kg/day, p.o.) administration for another ten days. Subsequently, the blood pressure was monitored. Furthermore, the kidney homogenates were assayed for ACE activity and gene expression, as well as oxidative stress markers. RESULTS: The increased (systolic = 297 ± 59.30 mmHg; diastolic= 242 ± 51.96 mmHg) blood pressure, arginase activity, and reduced nitric oxide level were significantly ameliorated in hypertensive rats treated with the seed. However, the elevated ACE activity was significantly reduced but not the upregulated ACE1 gene. Also, the reduced antioxidant enzyme activities were ameliorated with a significant downregulation in their regulator-Nrf2. Rutin (4.07 ± 0.02 mg/g) and quercitrin (4.06 ± 0.01 mg/g), among others, were found in the seed. DISCUSSION: This study suggests that moringa seed offers its antihypertensive properties by acting as an ACE inhibitor but not its gene modulator, and also modulates the antioxidant system through interaction with Nrf2. CONCLUSION: Moringa seed could act as an ACE inhibitor and not its gene modulator.

ABSTRACT

Modern agriculture is primarily concerned with enhanced productivity of field crops linked with maximum resources use efficiency to feed the increasing population of the world. Exogenous application of biostimulants is considered a sustainable and ecofriendly approach to improve the growth and productivity of agronomic and horticultural field crops. The present study was carried out to explore the comparative growth enhancing potential of plant biostimulants (moringa leaf extract at 3% and sorghum water extract at 3%) and synthetic growth promoters (ascorbic acid at 500 µM and hydrogen peroxide at 100 µM) on growth, productivity and quality of quinoa crop (cultivar UAF-Q7) because it has gained significant popularity among agricultural scientists and farmers throughout the world due to its high nutritional profile. A field experiment was carried out at the Research Area of Directorate of Farms, University of Agriculture, Faisalabad, Pakistan during quinoa cultivation season of 2016-2017 and repeated during next year (2017-2018). All the foliar treatments enhanced the physiological, biochemical, quality, growth and yield attributes of quinoa as compared to control group. However, maximum improvement was observed in chlorophyll a and b contents, photosynthesis and respiration rates, and water use efficiency by moringa leaf extract (MLE) application. MLE application was also found more responsive regarding the improvement in activities of peroxidase, catalase, superoxide dismutase, phenolics and glycine betaine as compared to other treatments. Mineral elements i.e. K, Ca and N in root as well as in shoot were found the highest in response to MLE application. Similarly, growth (plant fresh and dry biomass, plant length and grain yield) and grain quality parameters (protein, K and Ca) were also significantly enhanced. Application of MLE was found to be a viable approach to improve the growth and quality of produce as compared to synthetic compounds.

ABSTRACT

COVID-19 caused by SARS-CoV-2 is responsible for the deaths of millions of people worldwide. It is having devastating effects on the people of all countries. In this regard, the phytochemicals of medicinal plants could be explored to prevent this disease. M. oleifera is a miracle plant with antibacterial, antiviral, and antioxidant properties because of its high content of flavonoids, glucosides and glucosinolates. Therefore, we constructed a library of 294 phytochemicals of M. oleifera and filtered it through the FAF-Drugs4. Further, molecular docking studies of filtered phytochemicals were performed with Mpro enzyme to investigate the binding interactions. Drug likeness properties, ADMET prediction were analyzed to determine the therapeutic aspect of these compounds. Based on the binding energy score of the top 4 compounds, the results indicate that Vicenin-2 has the highest binding affinity (-8.6 kcal mol-1) as compared to the reference molecule (-8.4 kcal mol-1). ADMET result reveals that all top four compounds have minimal toxic effects and good absorption. Further, 500 ns molecular dynamics simulation of the top four compounds showed that Kaempferol-3-O-rutinoside and Vitexin have good stability with Mpro. These two compounds were then subjected for MMPBSA (last 50 ns) calculation to analyze the protein-ligand stability and dynamic behavior. Kaempferol-3-O-rutinoside and Vitexin showed very good binding free energy i.e. -40.136 kJ mol-1 and -26.784 kJ mol-1, respectively. Promising outcomes from MD simulations evidence the worth of these compounds for future drug development to combat coronavirus disease.Communicated by Ramaswamy H. Sarma.

ABSTRACT

Objective: To investigate the effects of Moringa leaves on the cognitive dysfunction and apoptosis of hippocampal neurons in diabetic rats induced by streptozotocin (STZ). Methods: Fifty male SD rats were selected, and 10 rats were randomly selected as the control group. The other 40 rats were treated with STZ at the dose of 25 mg/kg by intraperitoneal injection. The 40 diabetic rats were randomly divided into model group, Moringa oleifera low-dose, medium-dose and high-dose group. The rats in Moringa oleifera groups were treated with Moringa oleifera at the doses of 2.0, 4.0 and 8.0 g/kg by gavage, the control group and model group were treated with the same amount of normal saline once a day, for 8 weeks. Morris water maze test was used to evaluate the learning and memory ability of rats. Pathological changes of hippocampal neurons and expressions of Bax, caspase-3 and bcl-2 protein in each group were observed by the sections were stained with HE staining and immunohistochemistry. Enzyme linked immunosorbent assay (ELISA) was used to detect tumor necrosis factor-α (TNF-α) and interleukin-6 (IL-6) in rat. Results: compared with the control group, the blood glucose of the model group was increased significantly (P<0.01), and the blood insulin level was decreased significantly (P<0.05); compared with the model group, the blood glucose values of Moringa oleifera groups were decreased significantly (P<0.05, P<0.01), and the blood insulin levels of middle and high dose Moringa oleifera group were increased significantly (P<0.05, P<0.01). There was no significant difference in FBG and INS among the three groups (P>0.05). In Morris water maze test, compared with the model group, the latency of Moringa oleifera groups was significantly shorter (P<0.05); the residence time in target quadrant of Moringa oleifera groups with different doses was significantly prolonged (P<0.05). Compared with the model group, the contents of TNF - α, IL-6 and protein expression in low, medium and high dose groups of Moringa oleifera were decreased significantly (P<0.05). HE staining and immunohistochemical staining results showed that Moringa oleifera medium dose group was positive, brown yellow, fine granular, compared with the model group. The number of neuronal apoptosis was significantly reduced in the middle dose group (53.21±7.19,P<0.01); the protein expressions of Bax, caspase-3 and the ratio of Bax/Bcl-2 in hippocampus were significantly decreased in the middle dose group (P<0.05). Conclusion: The mechanisms of Moringa leaves on the cognitive dysfunction and apoptosis of hippocampal neurons may be related to regulating the protein expressions of Bax, Bcl-2 and Caspase-3, reducing the contents of inflammatory factors TNF-α and IL-6.

ABSTRACT

Quinoa (Chenopodium quinoa Willd.) has gained significant popularity among agricultural scientists and farmers throughout the world due to its high nutritive value. It is cultivated under a range of soil and climatic conditions; however, late sowing adversely affects its productivity and yield due to shorter growth period. Inorganic and organic phyto-stimulants are promising for improving growth, development, and yield of field crops under stressful environments. Field experiments were conducted during crop cultivation seasons of 2016-17 and 2017-18, to explore the role of inorganic (hydrogen peroxide and ascorbic acid) and organic [moringa leaf extract (MLE) and sorghum water extract (sorgaab)] phyto-stimulants in improving growth and productivity of quinoa (cultivar UAF-Q7). Hydrogen peroxide at 100 µM, ascorbic acid at 500 µM, MLE at 3% and sorgaab at 3% were exogenously applied at anthesis stage of quinoa cultivated under normal (November 21st and 19th during 2016 and 2017) and late-sown (December 26th and 25th during 2016 and 2017) conditions. Application of inorganic and organic phyto-stimulants significantly improved biochemical, physiological, growth and yield attributes of quinoa under late sown conditions. The highest improvement in these traits was recorded for MLE. Application of MLE resulted in higher chlorophyll a and b contents, stomatal conductance, and sub-stomatal concentration of CO2 under normal and late-sowing. The highest improvement in soluble phenolics, anthocyanins, free amino acids and proline, and mineral elements in roots, shoot and grains were observed for MLE application. Growth attributes, including plant height, plant fresh weight and panicle length were significantly improved with MLE application as compared to the rest of the treatments. The highest 1000-grain weight and grain yield per plant were noted for MLE application under normal and late-sowing. These findings depict that MLE has extensive crop growth promoting potential through improving physiological and biochemical activities. Hence, MLE can be applied to improve growth and productivity of quinoa under normal and late-sown conditions.

ABSTRACT

Five fettuccini formulations containing 5% (5MSP), 10% (10MSP), 15% (15MSP), 20% (20MSP), and 30% (30MSP) of moringa sprout powder (MSP) were produced aimed at improving the nutritional and bioactive profile of conventional pasta. A gradual increase of protein, lipids, fiber and mineral content was observed in fettuccine as the MSP amount increased, while carbohydrates were reduced. MSP-addition also increased the levels of thiamine, riboflavin, γ- aminobutyric acid, glucosinolates and the antioxidant activity in pasta. All pasta doughs showed similar rheological parameters. Textural properties decreased after MSP inclusion, but the values obtained were close to those of control. Incorporation of MSP up to 10% did not modify substantially the sensory attributes of fettuccine, but higher amounts had a negative impact. Thus, addition of MSP up to 10% is a promising technological approach to improve the nutritional and functional properties of pasta without compromising consumer acceptance.

ABSTRACT

Alphabaculovirus of Chrysodeixis chalcites (ChchNPV-TF1) has been investigated as a useful bioinsecticide against C. chalcites (Esper) (Lepidoptera: Noctuidae) in banana crops. This study investigated the effects of several substances on the persistence of ChchNPV-TF1 under field conditions in the Canary Islands. Natural photoprotective substances, such as moringa, cacao, green tea, benzopurpurine, charcoal, iron dioxide, benzimidazole, kaolinite, and bentonite, were first evaluated under laboratory conditions using a Crosslinker as UV light source at 200 J/cm2. The photoprotective substances were divided into three groups: low protection (0-8%; kaolinite), intermediate protection (48-62%; green tea, moringa, bentonite and cacao) and high protection (87-100%; charcoal, iron ioxide). Benzopurpurine and benzimidazole did not provide any photoprotective effects. Two of the substances that yielded the best results, 1% cacao and 1% charcoal, were selected for the open-field experiment in a banana plantation. The persistence of ChchNPV-TF1 OBs (occlusion bodies) on leaf surfaces with sunlight exposure was analysed by comparing the initial mortality of 2nd instar C. chalcites larvae with the mortality observed at various intervals postapplication. The mortality rates decreased over time in all treatments and were always higher in the UV-protective substance-treated parcels. The 1% charcoal treatment exhibited the highest protection in both the laboratory and field experiments. No specific interference of UV-protective substances on the maximum photochemical efficiency of banana plants was observed under field conditions.

ABSTRACT

Although the trends of international reports show an increase in overweight and obesity, even in developing countries, there are still areas of the world, such as Sub-Saharan Africa, strongly affected by undernutrition. Specifically, in Madagascar, the percentage of stunted children under 5 is extremely high. Furthermore, the COVID-19 pandemic is expected to increase the risk of all forms of malnutrition, especially in low-income countries, including Madagascar, with serious intergenerational repercussions. This narrative review aims at investigating eating habits and cooking methods of the Malagasy population, addressing sustainable healthy diets through promotion of novel foods. While novel foods are a recent concept, there are data that describe how they may contribute to counteract food insecurity and malnutrition considering context and place. Efforts to promote native, traditional foods as Moringa oleifera, an indigenous plant in Asia and Africa including Madagascar, rich in protein and micronutrients, as well as edible insects, alternative sustainable source of protein, lipids, iron, and zinc, would provide not only nutritional but also cultural and economic benefits. The potential synergies between food traditions and agroecology have the potential to impact health addressing larger issues of sustainability and food security. Regional, national, and international policies are needed to develop and support one health approach actions.

ABSTRACT

Moringa stenopetala is a medicinal plant that has been used in Ethiopian traditional medicine as a remedy for the treatment of hypertension, diabetes, and stomach pain. The study is aimed at assessing the toxicity of the methanol extracts of the seeds of Moringa stenopetala on the developing embryo and fetuses of rats. The seeds of Moringa were extracted by maceration using 80% methanol. The extract (250-1000 mg/kg) was orally administered to pregnant Swiss albino rats from days 6 to12 of gestation. Embryos and fetuses were recovered by laparotomy on gestational day 12 and day 20, respectively, and were assessed for developmental anomalies. On day 20, significant prenatal growth retardation such as reduced litter weight and crown-rump length were observed in near term fetuses of 1000 mg/kg treated rats. Litter weight in 1000 mg/kg and pair-fed control groups was 2.41 g ± 0.108 and 3.08 g ± 0.093, respectively. Delay in the development of an otic, optic, and olfactory system, as well as a reduction in a number of branchial bars, occurred on day 12 embryos of 1000 mg/kg treated rats. The rate of fetal resorption in 1000 mg/kg and pair-fed control groups was 1.6 ± 0.55 and 0.42 ± 0.52, respectively. There was also a high incidence of fetal death in the 1000 mg/kg treated group but it was not statistically significant. The offspring's of Moringa-treated rats did not show gross external malformations at all doses. These findings suggest that the methanol seed extract of Moringa stenopetala is not safe to rat embryos and fetuses. Its toxic effects were evidenced by a significant delay in embryonic and fetal development and an increase in fetal resorptions and fetal death.

ABSTRACT

The addition prebiotics in broiler diets can benefit digestion and nutrient abortion. The objective of the present study was to evaluate the effects of moringa leaf powder and agave inulin on growth performance, intestinal morphology, and slaughter traits of broiler chickens over 40 d of grow-out. A total of 280 broilers (Ross 308) aged 1 d were randomly allocated to 4 treatments, with 7 replicates each and 10 chicks per replicate: T1 = control diet, T2 = control diet with 15 g/kg of moringa leaf powder, T3 = control diet with 15 g/kg of agave inulin, and T4 = control diet with 15 g/kg of moringa leaf powder and 15 g/kg of agave inulin. The results showed that analysis of treatments at time were not different (P > 0.05) for broiler weights, feed and water intake, and weight gain. Treatment was significant (P < 0.05) for feed efficiency at 22 to 40 d; the T4 group presented higher (P < 0.05) values, and the T1 group presented lower (P < 0.05) values. However, the villus lengths of intestinal sections were different (P < 0.05) among treatments. In the duodenum, jejunum, and ileum, villus lengths were highest (P < 0.05) in the T2 group and lowest (P < 0.05) in the T3 and T4 groups. Villus widths in the duodenum and ileum were highest (P < 0.05) in the T2 group, but the T1 group showed highest (P < 0.05) values in the jejunum sections. The T3 and T4 groups showed lowest (P < 0.05) values in villus width in the duodenum, jejunum, and ileum. Thigh yield was highest (P < 0.05) in the T2 group and lowest (P < 0.05) in the T4 group. The T1 group exhibited the highest (P < 0.05) piece yields for leg, wing, and hip-back. The T4 group showed lowest (P < 0.05) leg and wing yields. Moringa leaf powder and agave inulin at a concentration of 15 g/kg in diets did not affect broiler performance, whereas moringa leaf powder improved intestinal morphology and thigh yield, and agave inulin improved leg yield. The results demonstrated benefits of these 2 feed additives to improve intestine health and meat yield in broilers over a 40-day grow-out.

ABSTRACT

Iron deficiency anaemia (IDA) is a common nutritional disorder worldwide. Sustainable food-based approaches are being advocated to use high and bioavailable dietary iron sources to prevent iron deficiency. The study investigated the bioaccessibility and bioavailability of iron from some plant products. Total iron levels in the samples were measured by inductively coupled plasma optical emission spectrometry (ICP-OES). Fractionation of the iron from the digested extracts was carried out by centrifugation and ultrafiltration. Iron bioavailability was determined using an in vitro simulated peptic-pancreatic digestion, followed by measurement of ferritin in Caco-2 cells. The highest amount of bioaccessible iron was obtained from moringa leaves (9.88% ± 0.45 and 8.44 ± 0.01 mg/100 g), but the highest percentage bioavailability was from baobab fruit pulp (99.7% ± 0.13 and 1.74 ± 0.01 mg/100 g) respectively. All the plant products, except for baobab, significantly inhibited iron uptake from FeSO4 and FAC, with fenugreek sprout being the most inhibitory.

ABSTRACT

Globally, salinity threatens the agricultural crops productivity by inhibiting plant growth and development through osmotic stress and ionic cytotoxicity. The polygenic nature of salinity offers several pragmatic shotgun approaches to improve salinity tolerance. The present study investigated the potential of glutathione (GSH; 1 mM) as an antioxidant and moringa leaf extract (MLE; 3%) as an organic biostimulant applied in sequence as seed priming and foliar spray on wheat growth, physiology and metabolic adaptation under saline conditions (9.16 dS m-1). Plants without any treatment and water spray (H2O) were considered controls. Salinity induced osmotic stress reduced the plant tissue water status and photosynthetic performance, and perturbed ionic (K+/Na+, Ca2+/Na+, K++Ca2+/Na+) and hormonal (IAA, GA3, zeatin, ABA) homeostasis, consequently affected growth and yield in wheat. Sequenced applied MLE and/or GSH improved osmotic stress tolerance by stabilizing membrane integrity and decreasing electrolyte leakage. These positive results were owed to enhanced endogenous GSH and ascorbate levels. Improved tissue water status was attributed to increased osmotic adjustment, better ionic and hormonal homeostasis contributed to improving photosynthetic efficiency and growth under salinity. Exogenously applied MLE and GSH sequences improved grain yield, which was attributed to the maintenance of green leaf area and delayed senescence associated with an increase in photosynthetic pigments and chlorophyll fluorescence traits. In crux, exogenous applied MLE and/or GSH can be the best physiological strategy to reduce the deleterious effects of salinity and improve physiological and metabolic adaptation in wheat under saline field conditions.

ABSTRACT

Serum and breast meat antioxidative status of broiler chickens fed diets supplemented with moringa leaf meal (MLM), garlic rhizome meal (GRM) and their composite were assessed. Ninety-six-day old Cobb 500 broiler chickens were randomly allotted to four treatment diets: Diet 1 (control), Diet 2 (2.5 g/kg MLM), Diet 3 (2.5 g/kg GRM) and Diet 4 (1.25 g/kg MLM + 1.25 g/kg GRM). Serum superoxide dismutase concentrations were not significantly (P > 0.05) influenced by the diets, whereas there were increased serum catalase concentrations across all the treatment diets with birds on Diet 4 showing significantly (P < 0.05) higher means than those on the control. For the serum glutathione peroxidase, significant (P < 0.05) increases were observed among the broilers on Diets 2 to 4 with those on Diet 2 showing the highest significant difference (P < 0.05) with birds on the control diet. The meat catalase and cholesterol concentrations of the breast meat were not significantly (P > 0.05) influenced by the phytoadditives. However, significant (P < 0.05) decrease in lipid peroxidation was observed across the treatment diets when compared with the control, while the phytoadditives enhanced the breast meat glutathione peroxidase among the broilers on the Diets 2 and 4.

ABSTRACT

Over the past few decades, natural gums are extensively investigated by the researchers due to their beneficial physicochemical properties. Among them, the polysaccharide exudates obtained from the stem of the plant Moringa oleifera, known as moringa gum, is investigated widely in the food, pharmaceutical, and other areas. The moringa gum is used in the form of dried powder as a pharmaceutical excipient in various formulations. It is also derivatized either by grafting or by other chemical modifications for enhancing its properties. The research on moringa gum and modified moringa gum has diversified in numerous biomedical fields. However, summarization of these progress are not available in the literature. This article gives an overview of the collection, purification, structural elucidation, and modification of moringa gum. Moreover, the present review furnishes complete information on the various aspects of moringa gum and its applications in various industrial and biomedical fields.
