Abstract
The MeOH and CHCl3 extracts of the pericarps of Mallotus japonicus showed potential anti-tumor-promoter activity. Seven constituents of the CHCl3 extract and two derivatives from the most abundant constituent, mallotojaponin, markedly inhibited the incorporation of 3H-choline into phospholipids of C3H101/2 cells enhanced by 12-O-tetradecanoylphorbol-13-acetate (TPA), a potent tumor promoter.
