Constituents of Cannabis sativa, XXV. Isolation of two new dihydrostilbenes from a Panamanian variant.
Two new dihydrostilbene compounds (named cannabistilbenes I and II) were isolated from a polar acidic fraction of a Panamanian variant of Cannabis sativa grown in Mississippi. The structure of cannabistilbene I was shown to be 3,4'-dihydroxy-5-methoxy-3'-(3-methylbut-2-enyl)-dihydrostilben e (1) from spectral data which was confirmed by synthesis. There is spectral evidence to indicate that cannabistilbene II could be represented by either structure 3 or 4.
