A simple and widely applicable method for the simultaneous determination of 5 kinds of catechins, i. e., epigallocatechin (EGC), epigallocatechin gallate (EGCg), epicatechin (EC), epicatechin gallate (ECg) and catechin (C), and 3 kinds of methylxanthines, i. e., theobromine (TB), theophylline (TP) a...
