摘要
目的 研究决明子中总蒽醌的提取工艺。 方法 采用正交试验法进行优选 ,紫外分光光度法测定总蒽醌含量。 结果 乙醇浓度对提取有极显著性影响。 结论 最佳提取工艺为决明子粗粉 ,用 90 %乙醇回流提取 2次 ,每次 6倍量溶剂 ,提取 1h。
OBJECTIVE To study the extraction process for the total anthraguinones in Semen cassiae.METHODS The optimum extraction process was selected with the orthogonal design.The content of total anthraquinones was determined by uv-Spectrophotometry.RESULTS The alcohol concentration was remarkable factor in the test.CONCLUSION The optimum extraction process is as follows:adding 6 time amount of90 % alcohol into materials and refluxing and extracting for2 times,1 h every time.
