【摘要】 儿茶素、甘草提取物、迷迭香提取物、葡萄籽提取物、虎杖提取物和银杏叶提取物清除O2的能力IC50分别为6.16 μg/mL、42.13μg/mL、184.29μg/mL、15.86μg/mL、25.48μg/mL和33.47μg/mL;清除OH的能力IC50分别为0.59μg/mL、5.59μg/mL、39.89μg/mL、2.93μg/mL、7.15μg/mL和10.44μg/mL;清除H2O2的能力IC50分另U为0.69μg/mL、24.02μg/mL、16.80μg/mL、1.34μg/mL、27.27μg/mL和6.09μg/mL.儿茶素对3种主要氧自由基的清除能力均最强.更多还原

【Abstract】 Objective: To compare the scavenging capacities on oxygen radicals of natural plant antioxidants. Methods: Chemiluminescence. Results: The IC50 of scavenging O2 for catechin, the extraction from licorice、rosemary 、 grape seed、 pulygonum cuspidatum and ginkgo leaf were separately 6.16 μg/ml、 42.13 μg/mL、 184.29 μg/mL、 15.86 μG/mL、25.48 μg/mL and 33.47 μ/mL: The IC50 of scavenging OH were separately 0.59 μg/mL、 5.59 μg/mL、 39.89 μ/mL、2.93μg/mL、 7.15μg/mLand 10.44 μg/mL: The IC50 of scavenging H2O2 were separately 0.69 μg/mL、 24.02 μg/mL、16.80μg/mL、 1.34μg/mL、 27.27μg/mL and 6.09 μg/mL. Conclusion: The scavenging capacities of catechin is strongest.更多还原
