摘要
中药白头翁(Pulsatilla chinensis(Bunge)Regel)为毛莨科白头翁属植物,临床用于治疗阿米巴和细菌性痢疾。
A new triterpenoid glycoside 1 has been isolated from Pulsatilla chinensis (Bun-
ge) Regel. The structure of 1 has been elucidated as 23-hydroxybetulic acid 28-O-β-D-glu-
copyranosy 1(1→6)-β-D-glucopyranosyl ester. The sites of glycosylation and the sequence of
sugars in the glycoside can be determined unambiguously and total assignment of severely
overlapping ~1H NMR absorptions of sugar residues were achieved by a combined use of the
recently introduced 2 D RELAY-HOHAHA, 1 D multiple relay COSY, selective long-range
^(18)C DEPT and 1 D ROESY NMR techniques.
