标题：A Glycosidic Isoflavonoid from Viola hondoensis W. BECKER et H. BOISSIEU (Violaceae), and Its Effect on the Expression of Matrix Metalloproteinase-1 Caused by Ultraviolet Irradiation in Cultured Human Skin Fibroblasts
摘要：Isolation of the ethyl acetate soluble fraction from aerial parts of Viola hondoensis W. B ECKER et H. B OISSIEU yielded one major isoflavonoid glycoside, tectoridin-4′- O -β- D -glucoside. The structure of the compound was certainly determined by chemical analyses, as well as 1D- and 2D-NMR spectroscopy. The compound exhibited potent inhibitory activity against the expression of matrix metalloproteinase-1 caused by UV-irradiation in cultured human skin fibroblasts.
