Uses:
1.Pharmacological Action: Medicinal plants containing ursolic acidhave been used in folk medicine before it was known whichconstituents were responsible for their therapeutic effectiveness.Contemporary scientific research which LED to the isolation andidentification of ursolic acid revealed and confirmed that severalpharmacological effects, such as, anti-tumor, hepatoprotective,anti-inflammatory (oral and topical), anti-ulcer, antimicrobial,anti-hyperlipidemic and antiviral, can be attributed to ursolicacid1.
However,its anti-inflammatory (topical), anti-tumor (skin cancer), andantimicrobial properties are pertinent to the cosmeticindustry.
2.Anti-aging agent: Ursolic acid treatment improves the health ofskin and hair. Ursolic acid and its derivatives form oil-resistantbarriers on the skin and hair as they do in the waxy coating offruits6. Ursolic acid has been used to treat photoaged skin becauseit prevents and improves the appearance of wrinkles and age spotsby restoring the skin''s collagen bundle structures and itselasticity31. Concentrations of ursolic acid ranging from 0.01 to50 mg have been reported for inclusion in skin treatmentpreparations 32-33.
3.Hair growth stimulant: Ursolic acid and its isomer, oleanolic acid,have been used in to nics to enhance hair growth and prevent scalpirritation26, 27. Both triterpenoid compounds encourage hair growthby stimulating the peripheral blood flow in the scalp andactivating the hair mother cells. They also furnishalopecia-preventing and dandruff-preventing effects27.
4. Antimicrobial activity: β Ursolic acid (triterpenoid sapogeninfrom the ursan group) inhibited the growth of several strains ofstaphylococci28. Numerous ursolic acid containing plants from theLamiaceae family exhibited antibacterial/ fungal activity29. Theminimal inhibitory concentration of Rosmarinus officinalis,Origanum majorana, and Lavandula officinalis were 500, 250, and 500mg/cm3, respectively29. Ursolic acid also inhibited the growth ofMicrosporium lenosum and Candida albicans at 250mg/mL30.
