Abstract:
Ten compounds were isolated from the aerial part of Solanum rostratum by means of various chromatographic techniques such as silica gel, Sephadex LH-20, ODS and preparative HPLC. Their structures were identified as dioscin (1), hypoglaucin H (2), hyperin (3), isoquercitrin (4), isorhamnetin-3-O-beta-D-galactopyranoside (5), kaempferol-3-O-beta-D-glucoside (6), smilaxchinoside A (7), 26-O-beta-D-glucopyranosyl-3beta, 20alpha,26-triol-25 (R) -delta5,22-dienofurostan-3-O-alpha-L-rhamnopyranosyl (1 --> 2) -[ alpha-L-rhamnopyranosyl (1 --> 4)] -beta-D-glucopyranoside (8), beta-sitosterol (9), and daucosterol (10), on the basis of physicochemical properties and spectroscopic data analysis. Among them ,compounds 7 and 8 were isolated from the genus Solanum for the first time, and the remaining compounds were obtained from this plant for the first time.
