摘要：

The analysis of catechin and related polyphenolic compounds in crude tea extracts by direct infusing of the samples into the mass spectrometer is described in this report. The mass spectra of catechin and its analogues all produced strong deprotonated molecules in the negative ionization mode. Further structural elucidation was accomplished by tandem mass spectrometry. This study demonstrates the mass spectrometric capability to analyze different components in crude plant extracts without recourse to liquid chromatographic separation.
