Phenolic compounds fromDuchesnea chrysantha and their cytotoxic activities in human cancer cell

Abstract
Five phenolic compounds were isolated from 80% aq. acetone extract ofDuchesnea chrysantha. Their cytotoxicities were screened by the colorimetric tetrazolium assay (MTT assay). Gallic acid, methyl caffeate, protocatechuic acid and pedunculagin mildly inhibited the survival of PC14 and MKN45 human cancer cell. Brevifolin carboxylic acid showed a strong cytotoxic activity.
