Metabolite Identification
Common NamePebrellin
DescriptionPebrellin belongs to the class of organic compounds known as 8-o-methylated flavonoids. These are flavonoids with methoxy groups attached to the C8 atom of the flavonoid backbone. Thus, pebrellin is considered to be a flavonoid. Pebrellin is found, on average, in the highest concentration within peppermints (Mentha X piperita). Pebrellin has also been detected, but not quantified in, a few different foods, such as herbs and spices, pot marjorams (Origanum onites), and spearmints (Mentha spicata). This could make pebrellin a potential biomarker for the consumption of these foods. Based on a literature review very few articles have been published on Pebrellin.
