摘要：

Investigation of the leaves of Guarea trichilioides afforded nine cycloartane derivatives including the following seven novel ones: cycloart-24-en-3,23-dione, 23-hydroxycycloart-24-en-3-one (epimers), 3beta-hydroxy-cycloart-24-en-23-one, 25-hydroxycycloart-23-en-3-one, 3beta-21-dihydroxycycloartane and 3beta,21,22,23-tetrahydroxycycloartane-24(31),25-diene. The structures were assigned on the basis of spectral data and derivatization by chemical reactions.
