摘要
从清除DPPH自由基、清除超氧阴离子自由基(O2-)、清除羟自由基(-OH)三方面,对柞蚕丝胶的抗氧化性进行了研究。试验结果显示,5%柞蚕丝胶溶液和其胰蛋白酶酶解液,DPPH清除率分别为49.96%、10.6%;超氧阴离子自由基(O2-)清除率分别为20%、40%;羟自由基(-OH)清除率分别为40%、64%。试验表明,柞蚕丝胶具有一定的抗氧化活性。
The antioxidant effect of tussah sericin was studied through examinations of their DPPH radical scavenging ac-tivity,super oxide（O2-） radical scavenging activity, hydroxyl（-OH） radical scavenging activity. Results showed thatthe DPPH scavenging rate of 5 % tussah sericin and it＇s trypsin solution liquid were 49.96 % and 10.6 % , respectively;the super oxide（O2-）scavenging rate were 20% and 25% , respectively and the hydroxyl（- OH）scavenging rate were40% and 64%, respectively. These data suggest that tussah sericin has a certain antioxidant activity.
