摘要: 本论文建立了以硅胶G60作为薄层固定相,层析分离(TLC)绿茶中绿原酸,使用紫外分光光度法(UV)定量分析绿茶中绿原酸含量的TLC-UV法。对绿茶中的绿原酸的提取条件、点样量及方法的精密度、准确度等进行了考察。并对绿茶(20010312粤春茶叶厂生产)中绿原酸含量进行了测定,测定结果显示每克绿茶中含绿原酸9.12mg/g。

关键词: 绿茶, 绿原酸, TLC-UV, 药用成分

Abstract: A TLC- UV method was developed to separate and determine chlorogenic acid in green tea. The extract condition, extent of sample application, precision and accuracy of the TLC- UV method for chlorogenic acid in green tea were studied. Separation and determination of chlorogenic acid in green tea (20010312 YueChun) for assaying the medicinal component showed that the content of chlorogenic acid was 9.12mg/g in green tea.

Key words: Green tea Chlorogenic acid TLC- UV Medicinal component
