Buxus sempervirens L. (Buxaceae) is a shrub that is widely distributed in Eurasia and abundantly found in Turkey. H2O extracts of this plant have found extensive use in indigenous medicine (1). We have previously investigated alkaloids from the leaves of B. sempervirens (2-4), and the present study has led to the isolation and structure elucidation of two new steroidal alkaloids, (-)-O-acetyl-N-benzoylbuxidienine [1] and (+)-nor-16α-acetoxybuxabenzamidienine [2]. Their structures have been elucidated through extensive spectroscopic studies.
