摘要
该方法能够同时测定普洱茶中右旋儿茶素(+C)、表儿茶素(EC)、表没食子儿茶素(EGC)、表儿茶素没食子酸酯(ECG)、表没食子儿茶素没食子酸酯(EGCG)、没食子儿茶素(GC)、儿茶素没食子酸酯(CG)、没食子儿茶素没食子酸酯(GCG)和没食子酸(GA)九种儿茶素组分,各组分获得了理想的分离,且具有良好的线性关系。本方法快速、准确、重复性好,适用于普洱茶中上述9种儿茶素组分的定性及定量分析。
The nine components in tea,including D-catechin(+C),epicatechin(EC),epigallocatechin(EGC),epicatechin gallate(ECG),epigallocatechin gallate(EGCG),gallocatechin(GC),catechin gallate(CG),gallocatechin gallate(GCG)and gallic acid(GA) nine components in tea were simultaneously determined by HPLC method.Using the method,the separation of each component was ideal,and with a good linear relationship.The method was rapid,accurate,reproducible and suitable for the qualitative and quantitative analysis of nine components of catechins in the Puer tea.
