Scope and Contents
Contents
-Ethyl-2-pyrrolidinone-substituted flavanols (EPSF) are marker compounds for long-term stored white teas. However, due to their low contents and diasteromeric configuration, EPSF compounds are challenging to isolate. In this study, two representative epimeric EPSF compounds, 5'''
- and 5'''
-epigallocatechin gallate-8-C
-ethyl-2-pyrrolidin...
