Shogaol, also known as (6)-shogaol, is a pungent constituent of ginger similar in chemical structure to gingerol. Like zingerone, it is produced when ginger is dried or cooked.[1]

Shogaols are artifacts formed during storage or through excess heat, probably created by a dehydration reaction of the gingerols. The ratio of shogaols to gingerols sometimes is taken as an indication of product quality.[2]

The name 'shogaol' is derived from the Japanese name for ginger (生姜、shōga).

Shogaol is rated 160,000 SHU on Scoville scale. When compared to other pungent compounds, shogaol is moderately more pungent than piperine, but less than capsaicin.

Pharmacology

Among ginger constituents, it has a very strong antitussive (anti-cough) effect.[medical citation needed] Both shogaol and gingerols reduced blood pressure and gastric contraction.[4] Shogaol has been shown to induce apoptosis (kill) in human colorectal carcinoma cells via reactive oxygen species.[5] It is broken down into 16 metabolites via the mercapturic acid pathway.[4] Acetylcysteine was found to reduce effectiveness of shogaol's apoptotic properties.[5]
