Chemistry: Ursolic acid [(3)-3-Hydroxyurs-12-en-28-oic acid] rarely occurs without its isomer oleanolic acid [(3)-3-Hydroxyolean-12-en-28-oic acid] They may occur in their free acid form, or as aglycones for triterpenoid saponins which are comprised of a triterpenoid aglycone linked to one or more sugar moieties. Ursolic and oleanolic acids are similar in pharmacological activity.

Toxicity: Notwithstanding its numerous cosmetic properties, ursolic acid is an ideal cosmetic ingredient because its overall toxicity (both chronic and acute) is low. It is not a primary irritant or sensitizer. In fact, it has been termed dermatologically innocuous.


Ursolic acid is a pentacyclic triterpene acid, used in cosmetics, that is also capable of inhibiting various types of cancer cells by inhibiting the STAT3 activation pathway and human fibrosarcoma cells by reducing the expression of matrix metalloproteinase-9 by acting through the glucocorticoid receptor.
