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
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.
Ursolic acid is also known as Prunol, Malol, Urson, beta-Ursolic
acid, NSC4060, CCRIS 7123, CHEBI:9908, TOS-BB-0966, and
3beta-Hydroxyurs-12-en-28-oic acid. As medicine it is well
tolerated and can be used topically and orally.
Ursolic acid is present in many plants, including apples, basil,
bilberries, cranberries, elder flower, peppermint, lavender,
oregano, thyme, hawthorn, prunes.
Contemporary scientific research which led to the isolation and
identification of ursolic acid revealed and confirmed that several
1.such as antitumor, hepatoprotective,
2.anti-inflammatory (oral and topical),
4.anti-hyperlipidemic, sedation, antioxidation and antiviral,
5.hair growth stimulant,can be attributed to ursolic acid which is
widely used in medicine.It can inhibit Elastase.
6.However, its anti-inflammatory (topical), antitumor (skin
cancer), and antimicrobial properties make it useful in cosmetic
