Oleanolic acid 3-acetate, also known as 3-O-acetyloleanolic acid, is a member of the class of compounds known as triterpenoids. Triterpenoids are terpene molecules containing six isoprene units. Oleanolic acid 3-acetate is practically insoluble (in water) and a weakly acidic compound (based on its pKa). Oleanolic acid 3-acetate can be found in black-eyed pea and rosemary, which makes oleanolic acid 3-acetate a potential biomarker for the consumption of these food products.
