title: New tirucallane-type triterpenoid saponins from Sapindus mukorossi Gaetn.
abstract: Two new tirucallane-type triterpenoid saponins, sapimukoside C (1) and sapimukoside D (2), have been isolated from the roots of Sapindus mukorossi Gaetn. Their structures have been determined, on the basis of spectral and chemical analysis, as 3-O-alpha-L-rhamnopyranosyl-(1-->2)-[alpha-L- arabinopyranosyl-(1-->3)]-beta-D-glucopyranosyl (21,23R)-epoxyl tirucalla-7,24-diene-(21S)-ethoxyl-3 beta-ol (1) and 3-O-alpha-L-rhamnopyranosyl-(1-->2)-[alpha-L-arabinopyranosyl-(1-->3)]- beta-D-glucopyranosyl (21,23R)-epoxyl tirucall-7,24-diene-(21S)-methoxyl-3 beta-ol (2).
