title: Isolation and toxicological study of tetrahydrocannabivarol, an homolog of tetrahydrocannabinol (delta 1--THC).
abstract: Selection and culture in a Phytotron of plants of Cannabis sativa L. with high content of propyl-THC are obtained. Then it was possible to isolate a large quantity of propyl-THC by column chromatography. Spectroscopic analysis is done. Pharmacological tests are being run; first results revealed the allergenicity of this substance by comparison with the properties of tetrahydrocannabinol, the active principle of Cannabis.
