Antioxidant and Allelopathic Activities of Rice (Oryza sativa L.) Bran

Full Text PDF


Rice by-products had higher amount of nutrients when compared to the polished rice. In this study, rice bran was investigated for antioxidant and allelopathic activities as well as identified its potent phytochemicals. The methanol (MeOH) extract from 8.9 kg rice bran was dissolved in water and successfully extracted using hexane and ethyl acetate, then ethyl acetate crude extract was subjected to normal phase column chromatography using the eluent of n-chloroform:methanol. Of which, ten fractions was collected, among them the fraction 5 (Fr5), showed maximum antioxidant activity, followed by the Frs 6, 1, and 10. Accordingly, the Fr5 showed the greatest inhibitory on germination and elongation of roots and shoots of radish (Raphanus sativus). There were 10 phytochemicals have been identified in the Fr5. The utilization of the identified constituents should be further investigated.
