Oxoepistephamiersine, a New Hasubanalactam Alkaloid from Stephania japonica[Reference: WebLink]

METHODS AND RESULTS:
A new hasubanalactam alkaloid, Oxoepistephamiersine (1), was isolated together with known alkaloids, oxostephamiersine (2) and lanuginosine (3), from the petroleum ether extraction of the roots of Stephania japonica. The new alkaloid is the seventh hasubanalactam congener isolated from the Stephania genus.
