Abstract
Abstract Two new cycloartane triterpenoids, (24?R)-cycloartane-3β,24,25,30-tetrol (1) and (24?R)-24,25,30-trihydroxy-9,19-cycloartane-3-one (2), along with three known compounds (3-5) were isolated from leaves and twigs of Aphanamixis polystachya. The new compounds were elucidated based on comprehensive spectroscopic analysis, including 1?D, 2?D NMR and HREIMS. The in?vitro cytotoxic activities evaluation of five human cancer cell lines revealed that compound 1 exhibited cytotoxic activity on all of tested human cancer cell lines, while compound 2 only had specific activity on SMMC-7721 cell line.
