Three new cycloartane triterpene glycosides from Souliea vaginata.
Three new cycloartane triterpene glycosides, soulieosides A (1), B (2), and C (3), were isolated from the rhizomes of Souliea vaginata, and their structures were elucidated on the basis of extensive NMR experiments and chemical methods. Soulieosides A-C were assigned as 25-O-acetylcimigenol-3-O-beta-D-(2-acetyl)xylopyranoside (1), 24-O-acetyl-isodahurinol-3-O-beta-D-(2-acetyl)xylopyranoside (2) and 20(S),22(R),23(S),24(R)-16beta:23;22:25-diepoxy-3beta,23,24-trihydroxy-9,19-cyclolanostane-3-O-beta-D-(4-acetyl)xylopyranoside (3), respectively.
