Studies on the Alkaloids of Formosan Lauraceous Plants. XI. : Alkaloids of Litsea cubeba PERSOON. (2)

Abstract

Following the isolation of laurotetanine (I) and isocorydine (III) from Litsea cubeba PERSOON, N-methyllaurotetanine (II), m.p. 158∼159°, [α]³¹_D+126° (EtOH), was isolated and identified from the tertiary phenolic bases, and D-magnocurarine (IV) from the quaternary bases, as its iodide, m.p. 193∼194°, [α]³⁰_D-104° (EtOH), and as a picrate, m.p. 177∼179°.
