Function and Application
Ursolic acid in pharmaceutical industry
1. Liver protection
In the treatment of liver-related diseases, ursolic acid can quickly restore liver function. It has the characteristics of a fast, stable effect, and short treatment course.
Indian scholars Saraswat and others found that bulk ursolic acid powder can treat liver-damaged cells and protect the liver. The experiment shows that ursolic acid has an anti-cholestatic effect, and can increase bile flow. Pretreatment with ursolic acid can significantly increase the survival rate of rat liver cells.
2. Lower blood lipids and blood sugar
Ursolic acid has the effects of lowering blood lipids and resisting atherosclerosis, and the total effective rate of blood lipid treatment is 95%.
Capsules with ursolic acid extract as the main ingredient are mainly for primary hyperlipidemia and are Class II new drugs approved in China.
3. Antitumor
In recent years, studies shows that ursolic acid has anti-cancer and anti-tumor effects. It resists various carcinogens and cancer promoters, can inhibit tumor formation and growth, and also induces cancer cell differentiation. Rosemary extract ursolic acid has a wide range of anti-tumor effects and is very likely to become a new type of low-toxic and effective anti-cancer drug.
4. Antidepressant
Ursolic acid powder has a significant soothing effect on the central nervous system.
Research by Chinese scholar Tan Renxiang and others has confirmed that ursolic acid powder not only treats viral hepatitis but also has antidepressant effects. When using the ursolic acid extract as a treatment for depression it shows almost no side effects. As to using synthetic medicine, which has significant side effects such as easy relapse and suicidal tendencies after use, rosemary extract ursolic acid will be a better choice.


Ursolic acid in cosmetic
1. Anti-oxidation
As a strong antioxidant, ursolic acid has an obvious antioxidant effect and can scavenge free radicals. It can absorb ultraviolet rays and prevent pigmentation caused by ultraviolet radiation. It positively affects human anti-aging, skin freckle removal, and pigmentation removal.
2. Inhibit melanin, skin whitening and remove spots
Skin color mainly depends on the content and distribution of melanin. Melanin exists in the basal layer of the epidermis. Tyrosinase promotes the formation of melanin by catalysis, causing melanin to transfer from the basal layer to the outer layer of the epidermis, thus coloring the skin.
Ursolic acid can inhibit the activity of tyrosinase and the production of melanin by directly combining with tyrosinase. At the same time, ursolic acid also has the function of desalting the melanin on the outer layer, accelerating the decomposition and excretion of melanin, reducing skin pigmentation, and removing spots and freckles.
3. Anti-inflammatory & Antibacterial
Rosemary extract ursolic acid powder has anti-inflammatory, antimicrobial, antibacterial, and antifungal properties. It can not only prevent the growth of bacteria and fungi in the skin and skincare products, but also help wound healing.
4. Repair the skin barrier
Ursolic acid repairs damaged cells, improves skin barrier function, and rejuvenates the skin by increasing the ceramide and collagen content of the cuticle.
