Cannabis Compound Identification
Common NameEpicatechin
DescriptionEpicatechin, also known as alpha-catechin or epicatechol, belongs to the class of organic compounds known as catechins. Catechins are compounds containing a catechin moiety, which is a 3,4-dihydro-2-chromene-3,5.7-tiol. Epicatechin is a very hydrophobic molecule, practically insoluble (in water), and relatively neutral. Outside of the human body, Epicatechin is found, on average, in the highest concentration within a few different foods, such as chocolates, cocoa beans, and cocoa powders and in a lower concentration in strawberries, apricots, and hot chocolates. Epicatechin has also been detected, but not quantified in, several different foods, such as chickpea, corns, garden tomato, watermelons, and colorado pinyons. This could make epicatechin a potential biomarker for the consumption of these foods. A catechin with (2R,3R)-configuration. Epicatechin is expected to be in Cannabis as all living plants are known to produce and metabolize it.
