Alkaloids of Buxus hyrcana

New Triterpenoid Alkaloid Cholinesterase Inhibitors from Buxus hyrcana

“…Seven compounds have been previously reported from this species. [3][4][5][6] Continuing our studies on B. hyrcana, we report here the isolation, structure elucidation, and cholinesterase inhibitory activities of three new alkaloids, (+)-N-benzoylbuxahyrcanine (1), (+)-N-tigloylbuxahyrcanine (2), and (+)-N-isobutyroylbuxahyrcanine (3). The structures of these compounds were deduced from their spectral and crystallographic data.…”
