Cannabis leaves contain Δ2-tetrahydrocannabinolic acid, cannabidiolic acid, cannabidiolic acid, etc. According to another report, analysis of samples from 17 countries showed that cannabidiolic acid accounts for 3.8-41.7% of the acidic part of the leaves and is the main component of the leaves. In tropical countries, when or after cannabis matures, the cannabidiolic acid content The lowest, Central European countries have the highest when they are immature, and other warm and cold countries have a content rate in between. In addition, the content of these substances may change during storage and after physical effects such as heating and light. For example, Δ2-tetrahydrocannabinolic acid can be converted into cannabigerolic acid when exposed to sunlight, and can also be converted into cannabigerolic acid and cannabidiol in the dark for a long time. Therefore, the cannabidiolic acid in leaves that have been stored for a long time is not Its original composition is generated from Δ2-tetrahydrocannabinolic acid after exposure to light. Like other dioecious plants, the composition of plants of opposite sexes often differs from each other. In terms of nitrogen-containing substances, the total nitrogen and protein nitrogen in the leaves of male cannabis plants are often less than those in female plants, but there is no big difference in old leaves.

Acidic and dicarboxylic amino acids.
