Summarize
Ursolic acid, also known as ursolic acid, ursolic acid, is a pentacyclic triterpenoid compound extract from the bear fruit of the evergreen trailing shrub of the rhododendron family.

It has a special odor.

It obtained in anhydrous ethanol as large and glossy ribcrystal, and in dilute ethanol as fine as hairlike needle crystal.

mp285℃ ~ 288℃, [α]D20+66°(pyridine), easily soluble in dioxane, pyridine, soluble in methanol, ethanol, butanol, butanone, slightly soluble in acetone.

Slightly soluble in benzene, chloroform, ether, insoluble in water and petroleum ether.

It has sedative, anti-inflammatory, antibacterial, anti-diabetic, anti-ulcer, reducing blood sugar and other biological effects.

In recent years, it  found that it has anti-carcinogenic, anti-carcinogenic, induction of F9 teratoma cell differentiation and anti-angiogenesis.

Which is highly likely to become a new anti-cancer drug with low toxicity and high efficiency.

In addition, it has obvious antioxidant function and is a strong antioxidant.

The antioxidant effect of it plays a positive role in anti-aging, skin freckle removal and pigment removal of the human body.

So it widely used as a raw material for medicine and natural whitening cosmetics.

Efficacy and function
It is a triterpenoid compound found in natural plants, which has sedative, anti-inflammatory, antibacterial, anti-diabetic.

Anti-ulcer, lowering blood sugar and other biological effects. Ursolic acid also has obvious antioxidant function.

In addition, ursolic acid can inhibit cell cycle process, cell proliferation and metastasis inducing cell apoptosis.

And demonstrate its anticancer activity reducing tumorigenesis through multiple signaling pathways.
