摘要：

Twenty-three triterpenoid saponins (1-23) have been isolated from the aquoeus and ethyl acetate frac-tions of the stem bark of Hallea ledermannii. Among them, nine (1-9) are newly described, some of them containes uncommun natural 6-deoxy-D-allofuranose, 6-deoxy-D-allopyranose, and 6-deoxy-D-pyranose as a sugar moiety. This is the first report of the isolation and structural elucidation of these compounds from H. ledermannii. The chemical structure of the compounds was determined using NMR and HRMS data.
