目的对比分析不同采收期柿叶中总黄酮的含量。方法采用紫外-可见分光光度法，以芦丁为对照品，在510nm波长处对不同采收期的柿叶中总黄酮进行含量测定。结果7,8,9,10,11,12月6个不同采收期柿叶中总黄酮含量分别为：0.0962%，0.1306%，0.1485%，0.2803%，0.2746%，0.1984%。结论不同采收期柿叶中总黄酮的含量存在一定差异，以10月采收的柿叶中总黄酮含量最高。“,”Objective To compare of the content of total flavonoids in persimmon leaf from dif erent harvest time.Methods UV-visible spectrophotometry was applied using rutin as reference substance, the total flavonoids of persimmon leaf from dif erent harvest time were measured by UV-visible spectrophotometry at the 510 nm.Results The contents of total flavonoids in persimmon leaf devived from July,August,September,October,November,December were 0.0962%,0.1306%,0.1485%,0.2803%,0.2746%,0.1984%,respectively.Conclusion The content of total flavonoids in persimmon leaf from dif erent harvest time is dif erent,and the highest is the one from October.
