Phytochemical investigations on the ethanolic extract of the leaves of Boxers papillosa of Pakistani origin have resulted in the isolation of two new triterpenoidal alkaloids, (-)-2 alpha,16 alpha-diacetoxy-9 beta,11 beta-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 spectroscopic studies.
