Ursolic acid (sometimes referred to as urson, prunol, malol, or 3β-hydroxyurs-12-en-28-oic acid), is a pentacyclic triterpenoid identified in the epicuticular waxes of apples as early as 1920 and widely found in the peels of fruits, as well as in herbs and spices like rosemary and thyme.

Natural occurrence

Ursolic acid is present in many plants, such as

prunes). Apple peels contain large quantities of ursolic acid and related compounds.[3]

Potential biochemical effects

A number of potential biochemical effects of ursolic acid have been investigated, but there has been no clinical study demonstrating benefits to human health.

JURKAT leukemic T Cells leading to the reduction in proliferation and T cell activation.[7] Ursolic acid is a weak aromatase inhibitor (IC50 = 32 μM),[8] and has been shown to increase the amount of muscle and brown fat and decrease white fat obesity and associated conditions when added to diets fed to mice.[9] Under physiological concentrations, ursolic acid also induces eryptosis (the apoptosis-like suicidal cell death in defective red blood cells).[10] It has been found to reduce muscle atrophy and to stimulate muscular growth in mice,[11] also shows a potential cardioprotection.[12]

In mice, ursolic acid induces

beta-cell function in streptozotocin-induced diabetic mice fed a high-fat diet.[20] Ursolic acid increased skeletal muscle mass, as well as grip strength and exercise capacity, improved endurance, reduced the expression of the genes involved in the development of muscle atrophy, and decreased indicators of accumulated fatigue and exercise-induced stress.[21]

In rats, ursolic acid ameliorated high-fat diet-induced

hepatic steatosis and improved metabolic disorders in high-fat diet-induced non-alcoholic fatty liver disease.[22]

Uses

Ursolic acid can be found in plants that are used for cosmetics additives.[23] It can serve as a starting material for synthesis of more potent bioactive derivatives, such as experimental antitumor agents.[24]
