title: Two new cytotoxic compounds from Tapirira guianensis.
abstract: Two new cytotoxic compounds, 2-[10(Z)-heptadecenyl]-1,4-hydroquinone (1) and (4R,6R)-dihydroxy-4-[10(Z)-heptadecenyl]-2-cyclohexenone (2) have been isolated from a MeOH extract of seeds of Tapirira guianensis. The structures were established through spectral analysis of the isolates and their derivatives.
