Triterpenoids are terpene molecules containing six isoprene units. Corosolic acid is practically insoluble (in water) and a weakly acidic compound (based on its pKa). Corosolic acid can be found in guava, loquat, and olive, which makes corosolic acid a potential biomarker for the consumption of these food products. Corosolic acid is a pentacyclic triterpene acid found in Lagerstroemia speciosa. It is similar in structure to ursolic acid, differing only in the fact that it has a 2-alpha-hydroxy attachment . 2-alpha-Hydroxyursolic acid 2a-Hydroxyursolic acid 2alpha-Hydroxyursolic acid 2alpha,3beta-Dihydroxy-12-ursen-28-oic acid Colosic acid Corosolic acid C30H48O4 472.6997 472.355260024 10,11-dihydroxy-1,2,6a,6b,9,9,12a-heptamethyl-1,2,3,4,4a,5,6,6a,6b,7,8,8a,9,10,11,12,12a,12b,13,14b-icosahydropicene-4a-carboxylic acid corosolic acid 4547-24-4 CC1CCC2(CCC3(C)C(=CCC4C5(C)CC(O)C(O)C(C)(C)C5CCC34C)C2C1C)C(O)=O InChI=1S/C30H48O4/c1-17-10-13-30(25(33)34)15-14-28(6)19(23(30)18(17)2)8-9-22-27(5)16-20(31)24(32)26(3,4)21(27)11-12-29(22,28)7/h8,17-18,20-24,31-32H,9-16H2,1-7H3,(H,33,34) HFGSQOYIOKBQOW-UHFFFAOYSA-N belongs to the class of organic compounds known as triterpenoids.
