Oil of seeds is used in rheumatism.
EtOH(50%) extract of plant is spasmolytic, hypotensive and CNS depressant (Asolkar et al.,1992).
Cannabis yields 421 chemicals of various classes broadly divided as i) cannabinoids, ii) cannabispirans and iii) alkaloids. Principal constituent of the flowering tops of the pistillate plants, which are medicinally used and also abused, is a resin which contains more than 60 cannabinoids which are responsible for the narcotic and psychotominetic properties of Cannabis. The active compounds of Cannabis include cannnabinol, pseudocannabinol, tetrahydrocannabinol, cannadidiol, cannabigerol, cannabol, cannabinin, cannin, piperidine and cannabichromene.
he plant also contains volatile oil, alkaloids, choline trigonelline, spernidine and cannabisativine and flavonoid glycosides of vitexin and orientin. Roots contain steroids, triterpenes, amides, ß-sitosterol, friedelin, epifriedelinol, carvone, dihydrocarvone and a basic substance. The steam distilled volatile oil of the flowering tops contains 68 components, of which monoterpens and sesquiterpens are the major ones. Seeds contain base 1-(+)- isoleucine betaine (Ghani, 2003).
