Background: Since time immemorial, humans have always been interested in lipids for various uses, namely food, cosmetology, medicine, etc. Many seeds, sources of oils, are increasingly studied for their nutritional and therapeutic properties. Methods: The present study aims to valorize the vegetable oil obtained from the seeds of the Moringa oleifera plant widely cultivated in the southwest of Algeria, using the solid-liquid extraction technique. In addition, the fatty acid analysis of this oil, using the gas chromatography technique. Result: An oil yield of 30.43% was obtained, revealed that it contains ten different compounds. The characterization of the oil obtained (physico-chemical properties such as organoleptic properties, density, viscosity, refractive index) proved to comply with international standards and AFNOR standards. In addition, it turned out that Moringa oleifera oil has a very interesting antioxidant power. However, this oil did not show any antibacterial activity on the strains tested.

‘The Tree of Life' or 'Miracle Tree' is the name of the plant of Moringa oleifera (Shajna). Moringa oleifera is one of the important plants in plant kingdom. Its leaves and fruits are used as vegetable in Indian sub continent, at the same time each part of the plant rich with some important medicinal values. It is now considered as a valuable source of several unique products for the medicines against various diseases. The present review is to focus on the nutritive values, physico-chemical properties, phyto-chemicals and pharmacological activities of M. oleifera. Various parts of the plant like seeds, leaves, flowers, bark and fruits have been investigated for their significant pharmacological activity. Phyto-chemicals like flavanoid, anthraquinone, alkaloids, essential oils, tannic acid, carotene, glucose have been reported for significant antioxidant, hepatoprotective, anticancer, aphrodisiac, antiinflammatory, antihyperlipidaemic, antihyperglycaemic and antiulcer activities of Drumstick tree and emphasizes the need for further exploring available information.Asian J.

This study was aimed at evaluating the physico-chemical properties, antifungal and anti-sprouting efficacy of Moringa oleifera and Sesame indicum seed oil extracts. Physico-chemical parameters were determined and compared for both oils. There was significant (p < 0.05) difference observed between the refractive values (1.4570 and 1.4633), free fatty acid (FFA) (2.04 and 3.21 mg KOHg-1), acid values (6.08 and 6.43 mg KOHg-1), pH values (4.55 and 5.33), saponification values (210.75 and 215.57 mg of KOHg-1), peroxide values (5.40 and 5.80 meqO2/kg), specific gravity (0.8897 to 0.9161 g/cm3) and yield (8.25% and 32.02%) for cold press extracts of Sesame and Moringa seed oils respectively. In vitro antifungal efficacy of both oils (M. oleifera and S. indicum) against Aspergillus niger shows a range of 43.63% to 58.18% inhibition. No anti-sprouting effect was recorded across all concentrations tested for the two oils. However, the antifungal potential of both seed oil extracts (Moringa and Sesame) exhibited moderate inhibitory properties with the highest percentage inhibition at 48 hrs.
