Abstract
A study was made of brsssinosteroids present in seeds of Cannabis sativa L. Homogenized seeds were extracted with methanol and the extract was fractionated into a chloroform-soluble fraction, which was subsequently purified by chromatography. Bioactive substances in a rice-lamina inclination test were derivatized and analyzed by GC-MS. The brassinosteroids, castasterone and teasterone, were identified.
