| 摘要: |
| 采用乙醇浸提法对Solanum photeinocarpum茎总黄酮的提取工艺及其抗氧化性能进行了研究，探讨了溶剂浓度、温度、提取时间、料液比等因素对总黄酮含量提取的影响，并采用正交实验对提取工艺进行优化。结果表明，最佳提取工艺参数乙醇浓度为40%，提取温度为80 ℃，时间为1 h，料液比1∶16(g∶mL)。在此条件下测得总黄酮含量为4.39mg/g，提取物对羟自由基具有较好的清除效果。 |

| Abstract: |
| Extraction of total quantity flavone from So lanum photeinocarpum and its antioxidation activity were studied. The method of extracting total quantity of flavone and the effect of concentration of menstruum，temperature，time，ratio of material to liquid discussed. Meanwhile，the best conditions for extraction were chosen after complete rthogonal analysis. The best parametersare 40% ethanol as extractant，temperature on 80 ℃，extraction time by 1h，ratio of materialto liquid on 1∶16. In this case，the rate of extraction reached up to 4.39 mg/g. The extraction of S.photeinocarpum had the strong antioxidative effection on scavenging hydroxyl radical. |
