Ursolic Acid (CAS: 77-52-1) is a naturally occurring pentacyclic triterpenoid compound widely found in medicinal herbs and edible plants such as rosemary, holy basil, apples, and loquat leaves. Structurally, it belongs to the oleanane-type triterpenoids and is known for its broad biological activities and low toxicity profile.
As a bioactive natural ingredient, Ursolic Acid exhibits anti-inflammatory, antioxidant, anticancer, antimicrobial, and anti-aging properties. It has attracted significant scientific interest for its potential roles in metabolic regulation, skin protection, and muscle growth enhancement.
Ursolic Acid is also a well-recognized cosmetic and nutraceutical raw material, used in formulations for skin care, anti-aging, and weight management products due to its ability to promote collagen synthesis and inhibit elastase and tyrosinase activities.
Our Ursolic Acid ≥98% purity is produced under strict quality control, supported by full analytical documentation (COA, HPLC, MS, NMR), and is ideal for pharmaceutical, cosmetic, and biochemical research applications.
