What is the ursolic acid

Ursolic Acid , a carboxylic acid present in a wide variety of plants in the form of a free acid or an aglycone of triterpene saponines. It is also known as urson, prunol, micromerol, and malol, is a pentacyclic triterpenoid compound which naturally occurs in a large number of vegetarian food, medicinal herbs, and plants.



For What, and How is Ursolic acid Used?

Ursolic acid treatment improves the health of skin and hair. Ursolic acid and its derivatives form oil-resistant barriers on the skin and hair, just as they form the waxy coating of fruits. Ursolic acid has been used to treat photoaged skin, because it inhibits the appearance of wrinkles and age spots by restoring the skins collagen bundle structures and elasticity. Ursolic acid inhibits the action of elastase enzyme in the skin, thereby preventing the enzyme from attacking structural proteins. Ursolic acid also inhibits the inflam-matory enzymes cyclooxygenase and lipoxygenase.

Function and usage:

inhibition of Tumor promotion in Skin; Anti-inflammatory activity; Hair growth stimulant; antimicrobial activity, anti-aging agents.
