Abstract: Gallic acid derivatives are the chief compounds of phenolic acid in tea. They are important umami-enhancing compounds in tea beverage, and possess the effects of inhibiting IgE producton, enhancing cognition-anting depressant. A reversed-phase PHPLC coupled with SPE was developed to purify and to prepare high purity 3-O-galloyquinic acid and β-D-glucogalline from fresh tea leaves. The obtained fractions were successfully identified by LC/TOF-ESI-MS, 1H-NMR and 13C-NMR. This method is simple, effective for the preparation of gallic acid derivatives.

Key words: gallic acid derivatives, SPE, PHPLC, β-D-glucogalline, 3-O-galloyquinic acid
