Chavicine is a possibly pungent compound found in black pepper^[1] and other species of the genus Piper. It is one of the four geometric isomers of piperine.

In light, especially ultra-violet light, chavicine is formed from its isomer piperine. Its flavor has been reported as flavorless^[2]^[3] Chavicine will also re-isomerise back to piperine.^[4]
