Abstract

A new alkaloid (3) was isolated from the stems of Maackia tashiroi (Leguminosae), together with (—)-camoensidine, tashiromine, ammodendrine and six known lupin (quinolizidine) alkaloids. The structure of 3 was characterized as the Nl 5-oxide of (—)-camoensidine, possessing an indolizidine-quinolizidine ring system, by a combination of spectroscopic and chemical methods. © 1991, The Pharmaceutical Society of Japan.
