Abstract:
Oil extraction methods from moringa seeds using solvent extraction (hexane, petroleum ether), screw press oil extraction and rotary press oil extraction to enhance the quality and value of oil and seed meal were investigated in this study. The glucosinolates extraction from the moringa seed meal was carried out using microwave assisted extraction and ultrasound assisted extraction. Results show that rotary press oil extraction increased the yield of glucosinolates content from moringa seed meal compared to other oil extraction methods. The methanolic extraction was followed for extraction of glucosinolates, column chromatography was performed for purification and HPLC analysis was carried out for quantification of glucosinolates. The predominent glucosinolates present in Moringa oleifera of glucomoringin was quantified from the moringa seed meal. The concentration of glucomoringin 290.12 μg / g and 250.65 μg / g was obtained from UAE and MAE methods from the seed meal.
