Triterpenoids are terpene molecules containing six isoprene units. Tormentic acid is practically insoluble (in water) and a weakly acidic compound (based on its pKa). Tormentic acid can be found in loquat and olive, which makes tormentic acid a potential biomarker for the consumption of these food products. Tormentic acid is a bio-active isolate of Luehea divaricata and Agrimonia eupatoria. Tormentic acid derivatives have been synthesized and researched . 2,3,19-Trihydroxyurs-12-en-28-oic acid (2alpha,3beta)- Tomentic acid Tormentic acid Urs-12-en-28-oic acid, 2,3,19-trihydroxy-, (2alpha,3beta)- C30H48O5 488.6991 488.350174646 (1R,2R,4aS,6aS,6bR,10R,11R,12aR,12bR,14bS)-1,10,11-trihydroxy-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 (1R,2R,4aS,6aS,6bR,10R,11R,12aR,12bR,14bS)-1,10,11-trihydroxy-1,2,6a,6b,9,9,12a-heptamethyl-2,3,4,5,6,7,8,8a,10,11,12,12b,13,14b-tetradecahydropicene-4a-carboxylic acid 13850-16-3 CC1CCC2(CCC3(C)C(=CCC4C5(C)CC(O)C(O)C(C)(C)C5CCC34C)C2C1(C)O)C(O)=O InChI=1S/C30H48O5/c1-17-10-13-30(24(33)34)15-14-27(5)18(22(30)29(17,7)35)8-9-21-26(4)16-19(31)23(32)25(2,3)20(26)11-12-28(21,27)6/h8,17,19-23,31-32,35H,9-16H2,1-7H3,(H,33,34) OXVUXGFZHDKYLS-UHFFFAOYSA-N belongs to the class of organic compounds known as taraxastane, ursane, and bauerane triterpenoids. These are triterpenoids with a structure based on either the taraxastane, ursane, or bauerane skeleton. These are obtained by methyl migration in ring E of the oleanane backbone.
