This document describes a method for detecting EGCG in tea leaves. The method uses the Agilent ZORBAX SB-C8 column to separate a group of catechins in tea leaves under low pH conditions, and achieves good separation.
This document describes an application for analyzing Epigallocatechin 3-O-gallate (EGCG), a flavonoid found in green tea, which is recognized as a cancer-preventive compound. The method utilizes high-performance liquid chromatography to separate and detect specific catechins within the extract.
It describes a method developed for analyzing an actual extract of green tea.
The required injection volume is 5 pL.
