Abstract
The stem bark of Canella winterana collected in Florida yielded three new drimane sesquiterpenes. Their structures were elucidated from their spectral data as: 9-deoxymuzigadial, 9-deoxyisomuzigadial and 3β-acetoxypolygodial. The first two compounds, which are double bond isomers, could only be separated from each other on silver nitrate-impregnated silica gel.
