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

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. Shogaol has been shown to induce apoptosis (kill) in human colorectal carcinoma cells via reactive oxygen species. It is broken down into 16 metabolites via the mercapturic acid pathway. Acetylcysteine was found to reduce effectiveness of shogaol's apoptotic properties.

The HPLC measures the capsaicinoid(s) in ppm, which can then be converted to Scoville units using a conversion factor of 15, 20 or 30 depending on the capsaicinoid.Missing or empty
