| Abstract | Rice bran is an essential source of natural bioactive compounds with widely applications. This study aimed todetermine the effects of extraction methods on the bioactivities of the extracts. Jasmine and Riceberry rice bran were extractedusing 50% ethanolic maceration, cold pressed and subcritical dimethyl ether (DME) extraction. The extracts were analyzed forantioxidant, pro-collagen type I synthesis and 5?-reductase inhibition activities. The results showed that Riceberry rice branextract exhibited superior antioxidant activity than Jasmine rice bran extract. The highest pro-collagen type I synthesis of Jasmineand Riceberry rice resulted from subcritical DME extraction (50.91%) and maceration (46.99%) respectively. It is a newly foundthat the subcritical DME extract of Jasmine rice bran displayed the strongest 5?-reductase inhibition activity (73.14 %inhibition)resulting from the biological markers linoleic acid (22.39?0.61 %w/w) and oleic acid (39.48?1.07 %w/w). Therefore, subcriticalDME extraction is suitable for preparing rice bran extract for 5?-reductase inhibitor application. |
