Abstract
A new yohimbine-type indole alkaloid (1) was isolated from the stem bark of Mitragyna africanus (WILLD.) collected in Nigeria, along with known seven Corynanthe-type oxindole alkaloids, two secoiridoids, three lignans, and a quinovic acid derivative. Their structures were elucidated by spectroscopic analyses. © 2004 Pharmaceutical Society of Japan.
