摘  要:
本文主要研究了柿叶黄酮的醇法提取工艺。首先就乙醇浓度、回流时间、回流温度及固液比进行了单因素实验。然后结合单因素的实验结果,设计了四水平三因素正交试验,最终得到柿叶总黄酮的最佳提取工艺为:回流温度90℃,乙醇浓度55%,回流时间6h,提取工艺固液比为1:20。

摘  要:
The extraction methods and the affecting factors of the extraction of flavones from Diospyros kakl leaves by ethanolextracting were studied in this paper. According to single factor experiment, we design the orthogonal test. The best extractiontechnological conditions was 90℃ and the ratio of solid to liquid is 1:20 for 6h by solvent of 55% ethanol.
