Common NameUrsolic acid
DescriptionUrsolic acid is a ubiquitous triterpenoid in plant kingdom, medicinal herbs, and is an integral part of the human diet. During the last decade over 700 research articles have been published on triterpenoids research, reflecting tremendous interest and progress in our understanding of these compounds. This included the isolation and purification of these tritepernoids from various plants and herbs, the chemical modifications to make more effective and water soluble derivatives, the pharmacological research on their beneficial effects, the toxicity studies, and the clinical use of these triterpenoids in various diseases including anticancer chemotherapies. Ursolic acid (UA), a pentacyclic triterpene acid, has been isolated from many kinds of medicinal plants, such as Eriobotrya japonica, Rosmarinns officinalis, Melaleuca leucadendron, Ocimum sanctum and Glechoma hederaceae. UA has been reported to produce antitumor activities and antioxidant activity, and is reported to have an antioxidant activity. UA may play an important role in regulating the apoptosis induced by high glucose presumably through scavenging of ROS (reactive oxygen species). It has been found recently that ursolic acid treatment affects growth and apoptosis in cancer cells. (PMID: 15994040 , 17516235 , 17213663 ).
