Ursolic acid is a pentacyclic triterpene compound that forms large, shiny prisms when dissolved in anhydrous ethanol and fine, hair-like needles in dilute ethanol. It is soluble in methanol, acetone, and pyridine, and insoluble in water and petroleum ether. Molecular formula: C30H48O3, CAS 77-52-1, molecular weight: 456.7, EINECS: 201-034-0.
Excellent crystallinity
The pentacyclic triterpene structure of Ursolic Acid enables it to form regular, large crystals. After using the -20℃ low-temperature crystallization process, the crystal purity can reach more than 98%, and the product crystals are uniform, which is conducive to storage and stability.
Good biocompatibility
Based on the natural triterpene skeleton structure, the survival rate of Ursolic Acid on normal cells exceeds 95%, significantly reducing side effects and meeting the standards of pharmaceutical-grade raw materials.
Strong antioxidant properties
The conjugated structure of its molecular hydroxyl and olefin bonds can stably bind free radicals, allowing Ursolic Acid to show a clearance rate of more than 90% in scavenging DPPH free radicals, which is much higher than the level of general antioxidants.
Ligustrum lucidum (Family: Oleaceae) – leaves
Arctostaphylos uva-ursi (Family: Ericaceae) – leaves
Eriobotrya japonica (Family: Rosaceae) – loquat leaves
Paulownia tomentosa (Family: Scrophulariaceae) – leaves
Prunella vulgaris (Family: Lamiaceae) – whole herb
Ilex ferox (Family: Aquifoliaceae) – leaves
Ursolic acid is found in approximately seven plant families, 46 genera, and 62 species, and occurs both in free form and as glycosides bound to sugars.
Pharmaceutical industry
Used in the preparation of anti-inflammatory, sedative, anti-tumor, antibacterial, and hypoglycemic drugs.
Tumor prevention and treatment
It has significant effects in inducing cell apoptosis, inhibiting tumor cell proliferation and metastasis, and interfering with cancer-related signaling pathways.
Antioxidant health products
As a natural antioxidant ingredient, it is used in functional foods and health products.
Beauty cosmetics
Applied in skin care products, it has anti-inflammatory, antibacterial, and antioxidant properties, which help to improve the skin barrier and delay skin aging.
Food industry
As a natural functional additive, it enhances the nutritional value and health function of food.
To maintain the stability and activity of Ursolic Acid, it should be stored in a low-temperature environment of 2–8°C to ensure that it is not affected by high temperature and decomposed or changed in properties. It should be stored away from light, sealed, and moisture-proof to prevent oxidation reactions or product degradation caused by light or moisture.
