    Moringa oleifera of family Moringaceae, commonly known as Horseradish-tree or the Ben-oil tree is an exceptionally nutritious vegetable tree with a variety of medicinal uses, distributed in tropical and subtropical regions of the world. The tree's bark, roots, fruit (pod), flowers, leaves, seeds and gum are used as an antiseptic, anticancer, anti-inflammatory, hepatoprotective and in treating rheumatism, venomous bites and other conditions. The immature green pods, called ‘drumsticks’ are probably the most valued and widely used part of the tree for water purification (e.g. desalination of ocean salt water). The leaves are highly nutritious, being a significant source of beta-carotene, vitamin C, protein, iron and potassium used in soups and sauces. The present study focuses on concentration-dependent ferric reducing antioxidant power (FRAP), free radical scavenging (DPPH), total phenolics (TP), total antioxidant capacity (TAC) and reducing power (RP) of moringa leaf and fruit (pod) extract compared with standard antioxidant. A strong positive co-relation was observed between FRAP, DPPH, TP and RP activity. Comparatively, the antioxidant potential of fruit extract was more pronounced than the leaf extract and ethanolic extract showed better activity than aqueous. On the basis of our observations, we hypothesize that moringa fruit (pod) and leaves can be a potential source of natural antioxidants due to their marked antioxidant activity

    Moringa leaf herbal drink is a functional drink that is beneficial for the body. Moringa leaves, avocado leaves and lemons are ingredients that have active compounds that are good for the body, especially in warding off free radicals. An innovative Moringa leaf herbal drink was created with the addition of avocado and lemon leaves. The study aims to find out the effects of the addition of avocado and lemon leaves on herbaceous beverages in terms of the content of antioxidant activity and physical chemical properties such as total phenol, total flavonoids, pH, color intensity, total soluble density (TPT) and organoleptic tests. The test results were analyzed using Analysis of Variance (ANOVA) on SPSS applications with a significance of 5% when significant after the Duncan Multiple Range Test. (DMRT). The results of the study showed that the addition of avocado and lemon leaves to herbaceous soft drinks had no effect on antioxidant activity, total phenol, total flavonoids, pH, and organoleptic tests, and did not affect the total soluble density and color intensity

    Research about coagulation of iron and calcium have been conducted using moringa (moringa oleifera Lamk) seed coagulant through the variation of the concentration of moringa seed and depositional time. Moringa seeds were used in this research that moringa seeds are old and dry. Compounds of moringa seeds that play role in the coagulation process of iron and calcium are proteins. This research was conducted to determine the optimum concentration of moringa seed and optimum deposition time on the process of coagulation using moringa seed coagulant in order to obtain the percentage decrease in the levels of iron and calcium. Variations in the concentration of moringa seeds were used in this research are 100, 200, 300, 400 and 500 ppm and the settling time is 30, 60, 90, 120 and 150 minutes. The results showed that the concentration of moringa seed and deposition time influenced in the process of coagulation of iron and calcium. In iron coagulation, obtained optimum concentration of 400 ppm moringa seeds and optimum settling time is 90 minutes. In these conditions the iron content decreased by 68.00 ppm or 66.95% from its initial level of 99.8 ppm. While the calcium coagulation, moringa seeds obtained optimum concentration of 500 ppm and optimum settling time of 120 minutes, which in this condition calcium levels decreased by 241 ppm or 49.00% of the initial concentration is 492 ppm

    Aquatic pollution as a field has gained a lot of attention over the decades majorly because of the vital role the aquatic environment plays in the human lifecycle. Indusrial wastewaters are often generated and discharged into the environment without treatment. Toxicity of effluents from Synythetic Resin production plant were evaluated in this study. Acute toxicity (96-h LC50) was evaluated using 0.23, 0.31, 0.35 and 0.39 mg/L of the effluent in a renewal bioassay procedure. Physicochemical parameters of the effluent were also evaluated, the values obtained for lead, cyanide, total suspened solid, total hadness, total dissolved solids and alkalinity were higher than the Federal Environmental Protection Agency standard specification for effluent discharge into aquatic environment and as such contributed to the effluent's toxicity. Mortality increased as the concentrations of the effluent increases and 0.355mg/L was obtained as LC50. The research eventually revealed that the synthetic resin effluent has a high level of toxicity to catfish. Deleterious effects such as biomagnification and other abberations may occur in man if exposed to substantial concentration of the effluent

    Seasonal Variation in Leaf Growth and Antioxidant Content of Moringa oleifera Cultivated at Buenos Aires, Argentina

    The properties and applications of Moringa oleifera are so vast that it is called the "miracle tree". The objective of this work is to study the seasonal variations in the leaf antioxidant content and the scavenging activity on DPPH radicals in concordance with its growth on M. oleifera plants of two seed origin, Commercial (C, seeds that were obtained from a market) and Bolivia (B, seeds that were obtained from a commercial forest of Santa Cruz de la Sierra, Bolivia); the experiment was conducted at Buenos Aires, Argentina. Significant differences were found on leaf growth, antioxidant content and DPPH activity along the growing season. The lower leaf dry weight as percentage of fresh weight, higher specific leaf area, higher relative growth rate and lower phenol content on B leaves than C leaves could indicate that B plants are geared for a higher productivity rate of resource acquisition than C plants. Specific leaf area, leaf dry weight as percentage of fresh weight, phenol content and activity of DPPH radicals on leaf extracts were significantly correlated, which could be used on productivity estimation and nutraceutical valuation. The phenol content and activity of DPPH radicals of leaf extracts of B and C origins indicate that the leaves of the plants growing in the described conditions are of noteworthy value. These are the first antecedents for M. oleifera growing at Buenos Aires, Argentina, allowing to preliminary consider this area as one of the southernmost zone.Fil: Arena, Miriam Elisabet.

    Spice was produced using blends of Moringa oleifera leaf, ginger and garlic. The sensory, chemical and microbial assessment of Moringa based spice was evaluated. The formulation was grouped into nine blends in ratio 25:75:0, 20:80:0, 15:85:0, 25:0:75, 20:0:80, 15:0:85, 25:37.5:37.5, 20:40:40, 15:42.5:42.5 for Moringa-ginger-garlic respectively. Sensory evaluation revealed that blends with 20% moringa were more preferred in terms of aroma, taste, flavour, appearance, texture and overall acceptability. The most preferred blends were further subjected to proximate and microbial analysis. The proximate composition of the preferred blends were similar with moisture, protein, fat, ash and carbohydrate contents ranging between 8.1-9.2, 23.8-25.5, 2.7-3.0, 54.0-55.4% respectively. Microbial load of all the blends decreased during storage period. However, moringa-ginger blend showed significantly low microbial count compared to other blends. This study suggests that moringa based spice products with 20% inclusion of moringa are acceptable and can be use as spice in different household consumable product
