Common Name3-Epioleanolic acid
Description3-Epioleanolic acid, also known as 3-epioleanolate, belongs to the class of organic compounds known as triterpenoids. These are terpene molecules containing six isoprene units. 3-Epioleanolic acid is a very hydrophobic molecule, practically insoluble (in water), and relatively neutral. Outside of the human body, 3-Epioleanolic acid is found, on average, in the highest concentration within common sages. 3-Epioleanolic acid is found in Akebia trifoliata, Amphipterygium adstringens, Bergia capensis, Boschniakia rossica, Calceolaria pinifolia, Conandron ramondioides, Ekebergia capensis, Eremophila platycalyx, Eucalyptus occidentalis, Gardenia ternifolia, Lardizabala biternata, Lotus corniculatus, Mulguraea tridens, Ocimum basilicum, Olearia paniculata, Panax ginseng, Pilea pumila, Piranhea mexicana, Platycodon grandiflorus, Scutellaria discolor, Scutellaria strigillosa, Stauntonia hexaphylla and Viscum album. 3-Epioleanolic acid was first documented in 2000 (PMID: 10960904). This could make 3-epioleanolic acid a potential biomarker for the consumption of these foods.
