title: Matrix metalloproteinase-1 expression inhibitory compound from the whole plants of Viola ibukiana Makino.
abstract: Bioassay-guided fractionation has led to the isolation of two triterpenoid saponins 3-O-[O-beta-D-glucopyranosyl-(1 --> 3)-O-beta-D-glucopyranosyl] oleanolic acid (1), and 3-O-[O-beta-D-glucopyranosyl-(1 --> 2)-O-beta-D-glucopyranosyl] oleanolic acid (2) from the whole plants of Viola ibukiana Makino. Compound 2 showed matrix metalloproteinase-1 expression inhibition activities in a dose-dependent manner.
