Ursolic acid (UA) (3β-hydroxy-urs-12-en-28-oic-acid) (Fig. 1) is a pentacyclic triterpenoid carboxylic compound (C30H48O3) which may occur in the free acid form or as aglycones for triterpenoid saponins.

Its isomer, oleanolic acid (OA) (3β-hydroxy-olea-12-en-28-oic-acid), presents different substitution of the methyl group, but they have similar molecular structures and pharmacological activity. 

Oleanolic acid and ursolic acid are ubiquitous triterpenoids in plant kingdom, medicinal herbs, and are integral part of the human diet, once they are found in fruits and medicinal herbs.
