Abstract

3 Abstract: Soybean intake is inversely correlated with risks of several chronic diseases in human. Phytochemicals and in particular phenolic acids, flavonoids and isoflavonoids compounds present in soybean seeds may be partially responsible for these health benefits through their antioxidants activity. In a pot experiment, soybean plants was grown in sandy media and irrigated with Hoagland solution as inorganic treatment or grown under one of the three levels of compost i.e. 25, 50 and 75% alone or in a mixture with multi- bioorganic. Individual phenolic acids, quercetin, genistein and daidzein in seeds were quantified by HPLC. Changes in the levels of individual phenolics and less value of quercetin under various compost levels resulting in insignificant lower values of total phenolics and total flavonoids as compared with inorganic grown seeds. Adding multi-bioorganic to 50 or 75% compost treatments produce great enhancement effects on total phenolics, total flavonoids, protocatechuic acid, p-hydroxybenzoic acid, chlorogenic acid, caffeic acid, quercetin, genistein and daidzein contents as compared with other treatments. The most enhancement effect was exhibited phenolic acids, quercetin and genistein. Addition of multi-bioorganic to 50% compost treatments resulted in 68 and 40% increases in quercetin and genistein, respectively, as compare with inorganic treatment, as well as 90 and 47% increases, respectively, as compare with 50% compost alone. The highest values of antioxidant activity was determined in soybean seeds grown under 50 and 75% compost, especially when mixed with bioorganic. Using either 50 or 75%, compost in a mixture with bioorganic caused increases in antioxidant activity ranged between 25 and 60% when compared with other inorganic and compost alone treatments. These results indicate that bioorganic fertilizers play a role in determining antioxidant activity and phenolic metabolites of soybean seeds.
