Beschreibung

A spiroisoquinoline alkaloid from Stephania glabra, the base has [α]26D + 143° (c 1.88, CHCI3). It contains two methoxyl groups and an imino group and yields a crystalline N-acetyl derivative, m.p. 234-5°C; [α]24D- 80° (c 1.57, CHCI3). The N-methyl compound has been shown to be identical with Pronuciferine (q.v.).
