Phytochemical studies on the methanolic extract of the leaves of Buxus hyrcana pojark, collected
in Iran, have resulted in the isolation of two new triterpenoidal alkaloids, (+)-2α,16β ,31-
triacetylbuxiran (1), (+)-2α,16β ,31-triacetyl-9-11-dihydrobuxiran (2). Spectroscopic methods were
used to elucidate the structures of these new natural products.
