Abstract: In the present study, aqueous extract of bark of Moringa oleifera administered orally, was eva- luated for its antiurolithiatic potential in albino rats of Wistar strains. The stones were produced in this study by zinc disc foreign body insertion in the bladder supplemented with 1% ethylene glycol in drinking water. The reduction in weight of the stones was used as criteria for assessing the preventive or curative antiurolithiatic effect of the bark of this plant. Two doses of extract for prophylactic and curative groups were used. In both groups the oral administration of the extract of bark of Moringa oleifera has resulted in significant reduction in the weight of bladder stones compared to the control group.

Abstract: Factorial optimization and kinetics of coal washery effluent (CWE) coag-flocculation by Moringa oleifera seed has been investigated at room temperature based on standard method of bench scale jar test. Moringa oleifera coag-flocculant (MOC) was produced according to work reported by Ghebremichael. A 23 full factorial central composite design was employed for the experimental design and analysis of results with respect to optimization. The combined effects of pH, dosage and settling time on the particle (turbidity) removal was studied using response surface methodology. Kinetic data generated were confronted with specified kinetic models for the evaluation of functional kinetics parameters. The optimal values of pH, dosage and settling time were recorded at 8,400mg/l and 25 min, respectively. The results of the major kinetic parameters recorded are 2,0.002l/mg.min, and 0.79 min for order of reaction, coag-flocculation reaction rate constant and coagulation period, respectively. The minimum removal efficiency recorded was 95% at 3mins of coag-flocculation. The results, while re affirming MOC as efficient coag-flocculant, confirmed that theory of perikinetics holds for the studied system at the conditions of the experiment.

Asian Journal of Pharmaceutics , 2008,
Abstract: Films were prepared using 5 parts of 10% w/w of mucilage of gum of Moringa oleifera with different proportions of plasticizers: polyethylene glycol (PEG 400) (0.1, 0.15, 0.2, and 0.3), glycerin (0.15), and propylene glycol (0.2). The films were casted on glass plates and dried under controlled evaporation. Films prepared with 0.15, 0.2 part of PEG 400; 0.15 part of glycerin and propylene glycol showed satisfactory drying after 24 h. They were evaluated for following parameters water uptake, tensile strength, folding endurance, and water vapor transmission rate. The results obtained are comparable with films made from other polymers, and the gum can be used for preparing polymeric drug delivery systems and as film coating agent.

Abstract: This study focused on developing an efficient and cost effective processing technique for Moringa oleifera seeds to produce natural coagulant for use in drinking water treatment. The produced natural coagulant can be used as an alternative to aluminum sulphate and other coagulants and used worldwide for water treatment. This study investigates processing Moringa oleifera seeds to concentrate the bio-active constituents which have coagulation activity. Moringa oleifera seeds were processed for oil extraction using electro thermal soxhlet. Isolation and purification of bio-active constituents using chromatography technique were used to determine the molecular weight of the bio-active constituents. The molecular weight of bio-active constitu-ents found to be in a low molecular weight range of between 1000 – 6500 Dalton. The proposed method to isolate and purify the bio-active constituents was the cross flow filtration method, which produced the natu-ral coagulant with very simple technique (oil extraction; salt extraction; and microfiltration through 0.45 µm). The turbidity removal was up to 96.23 % using 0.4 mg/L of processed Moringa oleifera seeds to treat low initial turbidity river water between 34-36 Nephelometric Turbidity Units (NTU) without any additives. The microfiltration method is considered to be a practical method which needs no chemicals to be added com-pared to other researchers proposed methods. The natural coagulant produced was used with low dosages to get high turbidity removal which considered to be a breakthrough in this study and recommended to be scaled up for industry level. The product is commercially valuable at the same time it is minimizing the cost of water treatment.

Abstract: A single-layer Artificial Neural Network (ANN) model was developed to predict the removal efficiency of Ni(II) ions from aqueous solution using shelled Moringa Oleifera seed (SMOS) powder. Batch experiments resulted into standardization of optimum conditions: biomass dosage (4.0 g), Ni(II) concentration (25 mg/L) volume (200 mL) at pH 6.5. A time of forty minutes was found sufficient to achieve the equilibrium. The ANN model was designed to predict sorption efficiency of SMOS for target metal ion by combining back propagation (BP) with principle component analysis. A sigmoid axon was used as transfer function for input and output layers. The Levenberg–Marquardt Algorithm (LMA) was applied, giving a minimum mean squared error (MSE) for training and cross validation at the ninth place of decimal.

Abstract: This study was designed to evaluate the hepatoprotective and ameliorative effects of aqueous extract of Moringa oleifera (MO) leaves on the histologyof liver and hepatic reticular fibres integrity of adult Wistar rats following lead-induced hepatotoxicity. Twenty four adult Wistar rats, weighing 180 - 220 g, randomly assigned into four groups of six animals each were used for the study. Lead and Moringa oleifera were given orally to the rats. 24 hours after the last administration, animals were sacrificed, blood obtained by cardiac puncture and liver excised, fixed in 10% phosphate buffered formalin for histological and histochemical analysis. The activities of aspartate amino transferase (AST), alanine amino transferase (ALT) and alkaline phosphatase (ALP) were used as markers of hepatotoxicity and catalase (CAT) activity were used as marker to evaluate the anti-oxidant status of the tissue. Result showed that lead treatment increased markers of hepatic damage (ALT, AST and ALP) and decreased CAT activities. Histological studies reveal alterations of hepatic structure including hepatocytic vacuolations, sinuosoidal congestion and loss of reticular fibres following lead treatment. Treatment with MO prevented and reversed lead induced hepatic damage. In conclusion, this study shows that Moringa oleifera leaf extract has an appreciable ability to prevent hepatotoxicity caused by lead, partly as result of its chemical constituents which has hepatoprotective properties.

Abstract: El trabajo tuvo como objetivo evaluar el efecto de la inclusión de harina de soya, en forma de reactivo para simular el efecto de un concentrado proteínico, en la digestibilidad in vitro de la harina de piscidium (vainas) de moringa. Se evaluaron nueve tratamientos de piscidium de moringa:soya (100:0; 90:10; 80:20; 70:30; 60:40; 50:50; 40:60; 20:80 y 0:100), con un dise o completamente aleatorizado y tres réplicas por cada tratamiento. Se observó un incremento en la producción de gas con el aumento del porcentaje de inclusión de soya; la digestibilidad verdadera tuvo un comportamiento similar. En cambio, la producción de biomasa microbiana alcanzó su mayor valor con la inclusión de la soya al 10%. Se concluye que la adición de la soya mejora la digestibilidad de las vainas de moringa, y que la eficiencia óptima de aprovechamiento de esta dieta se alcanza con la inclusión del 10% de soya. The objective of this work was to evaluate the effect of the inclusion of soybean meal, in this case in a way of a lab reactive, simulating a conventional protein concentrate, on the in vitro digestibility of the meal from Moringa oleifera pods. Nine treatments of M. oleifera pods:soybean were evaluated (100:0, 90:10, 80:20, 70:30, 60:40, 50:50, 40:60, 20:80 and 0:100), with a completely randomized design and three replications per treatment. An increase was observed in gas production with the increase of the soybean inclusion percentage; the true digestibility had a similar performance. On the contrary, the production of microbial biomass reached its higher value with the inclusion of 10% soybean. The addition of soybean is concluded to improve the digestibility of the M. oleifera pods, and the optimum utilization efficiency of this diet is reached with the inclusion of 10% soybean.
