説明

A chemical examination of the aqueous acetone extract of commercial oolong tea has led to the isolation of four new acylated flavan-3-ols 1-4, together with the known compounds 5-13. On the basis of chemical and spectroscopic evidence, compounds 1-4 have been characterized as (-)-epiafzelechin 3-O-gallate (1), (-)-epicatechin 3-O-(4-O-methyl)-gallate (2), (-)-epicatechin 3-O-p-hydroxybenzoate (3) and (-)-epigallocatechin 3-O-cinnamate (4).
