Homocapsaicin is a capsaicinoid and analog andcongener ofcapsaicin inchili peppers (Capsicum). Like capsaicin it is anirritant. Homocapsaicin accounts for about 1% of the total capsaicinoids mixture[2] and has about half the pungency of capsaicin. Pure homocapsaicin is alipophilic colorless odorless crystalline to waxy compound. On theScoville scale it has 8,600,000 SHU (Scoville heat units).[1] Homocapsaicin isolated from chili pepper has been found in twoisomeric forms, both with a carbon-carbondouble bond at the 6 position (numbered from the amide carbon) on the 10-carbon acyl chain. One isomer has an additional carbon, a methyl group, at the 8 position and the other has a methyl group at the 9 position. Homocapsaicin (6-ene-8-methyl) is the more abundant isomer. Homocapsaicin with the double bond at the 7 position has never been found in nature, though its structure is widely reported on the Internet and in the scientific literature. Details of this misidentification have been published.[3]
