AbstractThree new triterpenoid saponins, xuedanglycosides A-C (1-3, resp.), along with six known ones, were isolated from the rhizomes of Hemsleya chinensis. By detailed analysis of the NMR spectra, by chemical methods, and by comparison with spectral data of known compounds, the structures of new compounds were determined to be 16 alpha,23 alpha-epoxy-2 beta,3 alpha,20 beta-trihydroxy-10 alpha,23 alpha-cucurbita-5,24-dien-11-on-2-yl beta-D-glucopyranoside (1), 2 beta,3 alpha,16 alpha,20 beta-tetrahydroxycucurbita-5,25-diene-11,22-dion-2-yl beta-D-glucopyranoside (2), and oleanolic acid 28-O-beta-xylopyranosyl-(1 -> 6)-O-beta-glucopyranoside (3). In addition, hemslecin A 2-O-beta-D-glucopyranoside (6), hemsamabilinin B (7), and hemslonin A (9) were obtained for the first time from this plant.
