Abstract

Five novel polyphenols have been isolated from the air-dried herb of Cistus salvifolius; they were characterized as epigallocatechin-3-O-(4-hydroxybenzoate), epigallocatechin-(4 beta-->8)-epigallocatechin, epigallocatechin-3-O- gallate-(4 beta-->8)-epigallocatechin, epigallocatechin-(4 beta-->6)-epigallocatechin-3-O-gallate and 1-O-beta-D- (6'-O-galloyl)-glucopyranosyl-3-methoxy-5-hydroxybenzene. In addition, the occurrence of several flavan-3-ols, epigallocatechin-(4 beta-->8)-epigallocatechin-3-O-gallate, 1-O-beta-D-glucopyranosyl-3-methoxy-5-hydroxybenzene and betuloside (= rhododendrin) was demonstrated.
