【摘要】 采用正交设计，以浸提温度、乙醇浓度和固液比为考察因素，对柿叶总黄酮的乙醇提取工艺进行了研究。结果表明，用１５ 倍柿叶重的５０ ％ 乙醇水溶液，在７５ ℃下浸提３ ｈ 为最佳条件。更多还原

【Abstract】 This paper dealt with the extraction technology of flavonoids from persimmon leaves by ethanol.Using the orthogonal design,we considered the effects of different temperatures,different concentrations of EtOH-H 2O and different amounts of EtOH-H 2O added during extraction on the contents of flavonoids in persimmon leaves.The largest extractive ratio got when extracting with 50% EtOH-H 2O for 3h at 90 ℃ at the ratio of solid to liquid for 1∶5.更多还原
