Metabolite Identification
Common Name7-Ethylrosmanol
Description7-ethylrosmanol is a member of the class of compounds known as diterpene lactones. Diterpene lactones are diterpenoids containing a lactone moiety. 7-ethylrosmanol is practically insoluble (in water) and a very weakly acidic compound (based on its pKa). 7-ethylrosmanol can be found in common sage and rosemary, which makes 7-ethylrosmanol a potential biomarker for the consumption of these food products.
