| 中文摘要: |
| 目的探讨沙蚕提取物的抗氧化活性。方法采用DPPH法观察沙蚕提取物的抗氧化活性，通过Sephadex LH-20凝胶过滤，对沙蚕提取物中的抗氧化物质进行了初步分离纯化。结果与结论沙蚕提取物具有较强的清除自由基（DPPH）的能力，通过定性分析方法确定该物质为一类小分子量的多肽类物质。 |
| English Summary: |
| Objective To study antioxidant activity of extracts from Perinereis aibuhite. Methods The extracts from Perinereis aibuhite were purified by using Sephadex LH-20 and its antioxidant activities were determined by the method of DPPH. Results and Conclusion The extracts from Perinereis aibuhite showed strong free radical scavenging activity, and it was identified as a group of low molecular weight peptides by qualitative analyzing method. |
