In recent years, it has been found that it has anti-carcinogenic, anti-cancer promoting, inducing differentiation of F9 teratoma cells and anti-angiogenesis effects. It is very likely to become a new anticancer drug with low toxicity and high efficiency. In addition, ursolic acid has obvious antioxidant function, so it is widely used as a raw material in medicine and cosmetics.
