Abstract:
To study the chemical constituents of the aerial parts of Pulsatilla chinensis (Bge.) Regel, various chromatography methods were used. Seven triterpene glycosides were isolated from the n-BuOH extract. Their structures were identified as bayogenin 28-O-alpha-L-rhamnopyranosyl (1 --> 4 ) -beta-D-glucopyranosyl (1 --> 6) -beta-D-glucopyranosyl ester (1), 3-O-alpha-L-arabinopyranosyl hederagenin 28-O-alpha-L-rhamnopyranosyl (1 --> 4) -beta-D-glucopyranosyl (1 --> 6) -beta-D-glucopyranosyl ester (2), 3-O-alpha-L-rhamnopyranosyl (1 -->-2 ) -alpha-L-arabinopyranosyl oleanolic acid 28-O-alpha-L-rhamnopyranosyl (1 --> 4 ) -beta-D-glucopyranosyl (1 --> 6 ) -beta-D-glucopyranosyl ester (3), 3-O-alpha-L-rhamnopyranosyl (1 --> 2 ) -[beta-D-glucopyranosyl (1 --> 4)] -alpha-L-arabinopyranosyl hederagenin 28-O-alpha-L-rhamnopyranosyl (1 --> 4) -beta-D-glucopyranosyl (1 --> 6) -beta-D-glucopyranosyl ester (4), 3-O-alpha-L-rhamnopyranosyl (1 --> 2) -alpha-L-arabinopyranosyl hederagenin 28-O-alpha-L-rhamnopyranosyl (1 --> 4) -beta-D-glucopyranosyl (1 --> 6 ) -beta-D-glucopyranosyl ester (5), hederagenin 28-O-alpha-L-rhamnopyranosyl (1 --> 4) -beta-D-glucopyranosyl (1 --> 6) -beta-D-glucopyranosyl ester (6) and pulsatilla saponin (7). Among them, compound 1 is a new compound. Compounds 2 -6 were isolated from this plant for the first time.
