Abstract:
To study the chemical constituents of Saxifraga stolonifera (L.) Meeb., chromatographic techniques were applied to separate and purify the compounds, and their structures were confirmed on the basis of physicochemical properties and spectral data. Ten compounds were isolated and identified as 5-O-methylnorbergenin (1), 3, 4-dihydroxyallylbenzene-4-O-beta-D-glucopyranoside (2), (7R, 8S)-4, 9, 9'-trihydroxyl-3-methoxyl-7, 8-dihydrobenzofuran-1'-propylneolignan-3'-O-beta-D-glucopyranoside (3), quercetin-3-O-beta-D-xylopyranosyl-(1 --> 2)-beta-D-galactopyranoside (4), kaempferol-3-O-alpha-L-rhamnopyranoside (5), (3S, 5R, 6R, 7E, 9R)-3, 5, 6, 9-tetrahydroxy-7-megastigmane (6), benzyl-O-alpha-L-rhamnopyranosyl-(1 --> 6)-beta-D-glucopyranoside (7), p-hydroxyacetophenone (8), pyrogallic acid (9) and p-hydroxyphenol (10). Compound 1 is a new compound. Compounds 2-10 were isolated from this plant for the first time.
