Phytochemical investigations on the ethanolic extract of the leaves of Buxus papillosa of Pakistani origin have resulted in the isolation of two new triterpenoidal alklaloids, (-)-2α,16α-diacetoxy-9β,11β-epoxybuxamidine (1) and (+)-papillozine-C (2) along with one known triterpenoidal base, (-)-sempervirone (3) isolated for the first time from this species. The structures of these natural products were established through detailed specroscopic studies.
