The fractionation of the dichlorometanic layer of dried stems of Michelia champaca afforded four substances: sinapyl 4-O-beta-D-glucopyranoside alcohol, sinapyl 4-O-beta-D-glucopyranoside aldehyde, syringaresinol and N-acetylnonaine. Part of the crude extract portion was submitted to acid-basic extraction allowed the identification of the alkaloid liriodenine. The two phenylpropanoids derivatives and the alkaloid N-acetylnonaine were been reported for the first time from Michelia genus. The alkaloid liriodenine and the lignan syringaresinol showed moderate antifungal activity.
