摘要:
Cyprotuoside C (1) and cyprotuoside D (2), two new cycloartane glycosides were isolated from the ethanol extract of the rhizomes of Cyperus rotundus. Their structures were identified as 24R-9,10-seco-cyclo-artan-1(10),9(11)-dien-3 beta,7 beta,24,25-tetraol 3-O-beta-D-xylopyranosyl-(1 -> 4)-[alpha-L-arabinopyranosyl-(1 -> 6)]-beta-D-glucopyranosyl-25-O-beta-D-glucuronide (1) and 9,10-seco-cycloartan-1(10),9(11),23(24)-trien-3 beta,7 beta,25-triol 3-O-beta-D-xylopyranosyl-(1 -> 4)-{alpha-L-arabinopyranosyl-(1 -> 6)-[alpha-L-rhamnopyranosyl-(1 -> 2)]}-beta-D-glucopyranosyl-25-O-beta-D-glucuronide (2) by spectroscopic methods.
