Metabolite Identification
Common NameDihydrocapsaicin
DescriptionDihydrocapsaicin is found in pepper (C. annuum). It is a potential nutriceutical. Dihydrocapsaicin is a capsaicinoid and analog and congener of capsaicin in chili peppers (Capsicum). Like capsaicin it is an irritant. Dihydrocapsaicin accounts for about 22% of the total capsaicinoids mixture and has about the same pungency as capsaicin. Pure dihydrocapsaicin is a lipophilic colorless odorless crystalline to waxy compound. It is soluble in dimethyl sulfoxide and 100 % ethanol.
