| 摘 要： | 研究了乙醇-水体系浸取银杏叶中黄酮类化合物的工艺条件,通过分光光度法测定黄酮的含量并计算它的浸出率。根据黄酮类化合物浸出率的计算结果,选用70%乙醇溶液为提取剂,并通过正交试验给出了黄酮类化合物的最佳浸出条件:浸取温度70℃,固液比1∶20,浸取剂pH=8,银杏叶中黄酮类化合物的浸出率可达到92.2%。

| Abstract: | Process for the extraction of flavones from Ginkgo leaves with ethanol-water was studied,and content of flavones was determined by spectrophotometry.The optimal condition was chosen by orthogonal tests as extraction with 70% ethanol at 70 oC,ratio of solid to liquid 1: 20 and at pH 8,and the extraction rate of flavones reach 92.2%. |
