Abstract:
By repeated column chromatography, including silica gel, toyopearl HW-40 and preparative HPLC, thirteen compounds (1-13) were isolated and purified from Smilax riparia. On the basis of spectral data analysis, the structures of isolated compounds were elucidated as 5-methoxy-[6]-gingerol (1), dehydroabietic acid (2), pteryxin (3), 2-methylphenyl-1-O-beta-D-glucopyranoside (4), 3,5-dimethoxy-4-hydroxybenzonic acid (5), isovanillin (6), vanillic acid (7), p-hydroxycinnamic acid (8), p-hydroxycinnamic methyl ester (9), p-hydroxybenzaldehyde (10), ferulic acid methyl ester (11), benzoic acid (12) and 5-hydroxy-methyl-2-furalclehyde (13). Compounds 1-4 and 8-12 were isolated from this genus for the first time. All compounds were isolated from this plant for the first time. Compounds 1 and 5-11 showed antioxidant activities on DPPH method.
