A new triterpenoid alkaloid, 16-deacetoxy-hyrcamine (1), together with six analogs, was isolated from the leaves and stems of Buxus sempervirens. Their structures were elucidated based on spectral methods and by comparison of the spectral data with those reported previously. All isolated compounds were evaluated for their growth inhibitory activity against human cell lines HL-60, SMMC-7721, A-549,MCF-7, and SW480. Compounds 1 - 4 and 6 showed modest cytotoxic activity against A-549, MCF-7, and SW480.
