Abstract

A new alkaloid, 2-methoxycanthin-6-one (1) has been isolated from the methanol extract of the stem wood of Quassia amara. In addition quassin (6) was also isolated. The structure of 1 was determined by spectroscopic methods.

Key words

Quassia amara - Simaroubaceae - canthin-6-one - alkaloids.
