Ursolic Acid

Ursolic Acid (CAS 77-52-1), also known as 3β-hydroxyurs-12-en-28-oic acid, is a naturally occurring pentacyclic triterpenoid widely distributed in the plant kingdom. It is commonly found in the peels of fruits such as apples, as well as in medicinal herbs including rosemary, thyme, oregano, and many other botanical sources.

This bioactive triterpene has been extensively studied in preclinical research. A systematic review and meta-analysis of animal and in vitro studies found that ursolic acid decreases inflammatory cytokine levels (such as IL-1β, IL-6, TNF-α), elevates antioxidant enzyme levels, and reduces oxidative stress markers. As a key marker compound in numerous plant extracts, ursolic acid serves as an important analytical reference standard for the standardization and quality control of herbal medicines, dietary supplements, and natural product formulations. High-purity ursolic acid enables accurate quantification and method validation in laboratories analyzing triterpenoid-rich botanicals. (Article reference)
