摘　　要：采用不同提取液、不同提取液倍数、不同提取方法对狼毒大戟进行了提取率的研究,同时对不同提取液及提取方法所得提取物质成分进行了分析。结果表明:以甲醇作为提取溶液采用6倍常温浸泡后索氏提取然后再常温浸泡的提取方法提取率最高,以95%乙醇作为提取液采用同样的提取方法其提取率次之;以95%乙醇、石油醚、乙酸乙酯作为提取液采用6倍常温浸泡后索氏提取再常温浸泡的提取方法较其他方法提取率高。甲醇在该方法下不仅提取率最高,而且其提取物所含成分也比较多,乙醇次之。由此可以得出,对于狼毒大戟的粗提取,采用甲醇或者乙醇作为提取溶液比较合适,其最佳提取方法为6倍常温浸泡后索氏提取然后再常温浸泡的提取方法。The extraction rate of Euphorbiafischeriana with different extracting solutions, different times of extracting solutions and different extraction methods were studied. And the components of the extracts by using different extracting solutions and extraction methods were analyzed. The results showed that the extraction rate of using methanol as extracting solution, soaking at 6 times of room temperature, Soxhlet extraction and soaking at room temperature was the highest. And the extraction rate of using 95% ethanol as extracting solution by the same extraction method was the next. The extraction rate of using 95% ethanol, petroleum ether and ethyl acetate as extracting solution, soaking at 6 times of room temperature, Soxhlet extraction and soaking at room temperature was higher than that of other methods. The extraction rate of using methanol as extracting solution by the same method was the highest and its extracts had most components, followed by ethanol. Therefore methanol and ethanol were suitable extracting solutions for crude extraction of E. fischeriana. The best extraction method was soaking at 6 times of room temperature, Soxhlet extraction and soaking at room temperature.
