Even higher organisms can be used for the production of labeled compounds. Plants, tobacco, or Canna indica for example, when grown in an exclusive atmosphere of radioactive carbon dioxide, [ 002], utilize the labeled precursor as the sole source of carbon for photosynthesis. After a suitable period of growth, almost every carbon atom in the plant is radioactive. Thus, plants can serve as an available source of C-labeled carbohydrates (9). 

Little is known of the chemistry of this family alkaloids have not yet been detected. Tests on 13 samples including nine species of Canna were without positive result Canna coccinea, C. Jlaccida, C. generalis, C. indica, Canna spp. (5). 

Cannabis resin, or Indian hemp, is derived from the dried flowering tops of pistillate plants of Cannabis sativa and C. indica (Canna-bidaceae). The plants contain 15-20% resin consisting mainly of AMetrahydrocannibol, or THC. THC is technically a benzotetrahy-dropyran and its structure derives from both phenolic and terpenic precursors (Bruneton 1995). It is in a molecular class of its own—the cannabinoids.
