摘要
目的:测定北虫草废渣废料蛋白酶解液对各种自由基的清除能力,为进一步开发和利用北虫草废渣废料提供实验依据。方法:与谷胱甘肽及北虫草酶解液对比,测定了北虫草废渣废料蛋白酶解液对DPPH自由基、羟基自由基和超氧阴离子自由基的清除能力。结果:北虫草废料酶解液对羟基自由基、超氧阴离子自由基和DPPH自由基的清除率为50%的浓度分别为0.023 mg/mL、1.07 mg/mL、0.215 mg/mL,随着酶解液浓度的增加,清除能力增强。结论:北虫草废渣废料蛋白酶解液对DPPH自由基、羟基自由基和超氧阴离子自由基的具有较强的清除能力。
Objective ： To measure the ability of clearance for all kinds of free radical in protease hydrolysate of waste. To pro- vide experiment basis for the further development and utilization of the waste north. Methods ： By comparing detected clearance ca- pability of DPPH frees radicals, hydroxyl radicals and superoxide anion free radicals. Results ： Clearance of percentage to hydroxyl radicals, superoxide anion free radicals, DPPH free radicals ：0. 023 mg/mL, 1.07 mg/mL,0. 215 mg/mL. Conclusion：The protease hydrolysate has a strong cleaning ability on DPPH free radicals,hydroxyl radicals and superoxide anion free radicals.
