title: Triterpenoid saponin from Viola hondoensis W. Becker et H Boss. and their effect on MMP-1 and type I procollagen expression.
abstract: Bioassay-guided fractionation has led to the isolation of triterpenoid saponins such as Acutoside A (3-omicron-[omicron-beta-D-glucopyranosyl-(1 --> 2)-omicron-beta-D-glucopyranosyl] oleanolic acid) from the whole plants of Viola hondoensis. Among them, Saponin 1 exhibited potent inhibitory activity against matrix metalloproteinase (MMP)-1, and prevented the UV-induced changes in the MMP-1 expression. In addition, compound was isolated from this plant for the first time.
