Cannabis Compound Identification
Common Namep-Hydroxyacetophenone
Description4'-Hydroxyacetophenone or p-Hydroxyacetophenone, also known as 4-acetylphenol or piceol, belongs to the class of organic compounds known as alkyl-phenylketones. These are aromatic compounds containing a ketone substituted by one alkyl group, and a phenyl group. 4'-Hydroxyacetophenone exists as a white to beige crystalline powder and is very soluble in water. It has a a mild, sweet, floral, balsamic odor and a very bland taste. It is used in the cosmetic industry as a perfuming agent and as an antioxidant. Industrially, 4'-Hydroxyacetophenone is used in the synthesis of several pharmaceutical drugs including octopamine, sotalol, bamethan, and dyclonine. 4'-Hydroxyacetophenone occurs naturally in many plants and plant foods and has been detected in coffee, cloudberries, cranberries, mangos, sweet oranges, sherry and in the needles and in mycorrhizal roots of the Norway spruce (Picea abies) (PMID: 2364913 ; PMID: 24197010 ). 4'-Hydroxyacetophenone is a potent xanthine oxidase inhibitor (PMID: 24712453 ) that appears to be even more potent than allipurinol. It is also one of several phenolic compounds found in cannabis smoke and is formed during the combustion of cannabis ( Ref:DOI ).
