Chemical composition

Cannabis leaves contain Δ2-tetrahydrocannabinolic acid, cannabidiolic acid, cannabichromic acid and so on. It is also reported that, analyzing samples from 17 countries, cannabidiolic acid accounted for 3.8-41.7% of the acidic portion of the leaf, which is the main component of the leaf; and also in the tropical countries when the cannabis is ripening or after the ripening of cannabis, cannabidiolic acid content is the lowest, in central Europe in the immature highest, and the other intermediate cold and warm countries, the content of the rate in the middle between the two. In addition, these substances, during storage and through physical effects such as heating, light, etc., the content may change. For example, Δ2-tetrahydrocannabinolic acid (THC) can be changed into cannabinolic acid by exposure to sunlight and into cannabinolic acid and cannabinol by prolonged exposure to darkness, so that the cannabinolic acid in long-stored leaves is not the original constituent of the leaf but is generated by exposure to light as a result of the Δ2-tetrahydrocannabinolic acid. As with other dioecious plants, there are often differences in the composition of heterosexual plants. In terms of nitrogen content, total and protein nitrogen are often lower in the leaves of male Cannabis plants than in females, but there is little difference in the older leaves. And male marijuana leaves of water-soluble protein than the female plant leaves contain more arginine, lysine, alanine, while the female plant leaves of water-soluble protein, contains more histidine, proline and dicarboxylic amino acids.
