摘要：

A novel quasi-dimeric oxidation product of (+)-catechin, formed during the radical-scavenging reaction that prevents lipid peroxidation, was isolated by chromatography, and its structure was elucidated by infrared, ultraviolet and H-1 and C-13 nuclear magnetic resonance spectra and mass spectrometry. It was 5'-[3-[3,4-(3',5'-dihydroxy) benzo-8-oxo-2,7-dioxabicyclo[4.4.0]deca-3,9-dien-10-yl]acryloyl]-(+)-catechin. It is an unusual type of dimer of flavan-3-ol derivatives, which is different from the naturally formed dimer, procyanidin.
