Two<i> p</i>-Quinonoid Aporphine Alkaloids from <i>Fissistigma balansae</i>

Abstract

Investigation of the ethanolic extract from the twigs of Fissistigma balansae resulted in the isolation of two new p-quinonoid aporphine alkaloids, named fissilandione (1) and norfissilandione (2). The structures of 1 and 2 were elucidated on the basis of spectral data and confirmed by chemical conversions.
