Ursolic 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). Ursolic acid is a pentacyclic triterpenoid that is urs-12-en-28-oic acid substituted by a beta-hydroxy group at position 3. It has a role as a plant metabolite and a geroprotector. It is a pentacyclic triterpenoid and a hydroxy monocarboxylic acid. It derives from a hydride of an ursane. Ursolic acid is a natural product found in Gladiolus italicus, Freziera, and other organisms with data available. Ursolic Acid is a pentacyclic triterpenoid found in various fruits, vegetables and medicinal herbs, with a variety of potential pharmacologic activities including anti-inflammatory, antioxidative, antiviral, serum lipid-lowering, and antineoplastic activities. Upon administration, ursolic acid may promote apoptosis and inhibit cancer cell proliferation through multiple mechanisms. This may include the regulation of mitochondrial function through various pathways including the ROCK/PTEN and p53 pathways, the suppression of the nuclear factor-kappa B (NF-kB) pathways, and the increase in caspase-3, caspase-8 and caspase-9 activities.

Oleanolic acid is a pentacyclic triterpene, found in the non-glyceride fraction of olive pomace oil (Olive pomace oil, also known as "orujo" olive oil, is a blend of refined-pomace oil and virgin olive oil, fit for human consumption). Pentacyclic triterpenes are natural compounds which are widely distributed in plants. These natural products have been demonstrated to possess anti-inflammatory properties. Triterpenoids have been reported to possess antioxidant properties, since they prevent lipid peroxidation and suppress superoxide anion generation. The triterpenes have a history of medicinal use in many Asian countries. Oleanolic acid exhibits both pro- and anti-inflammatory properties depending on chemical structure and dose and may be useful in modulating the immune response; further studies are required to confirm the immunomodulatory behaviour of this triterpenoid, and characterise the mechanisms underlying the biphasic nature of some aspects of the inflammatory response. Oleanolic acid is a ubiquitous triterpenoid in plant kingdom, medicinal herbs, and is an integral part of the human diet.

It has a role as a plant metabolite. It is a pentacyclic triterpenoid and a hydroxy monocarboxylic acid. It is a conjugate acid of an oleanolate. It derives from a hydride of an oleanane. Oleanolic acid is a natural product found in Ophiopogon japonicus, Freziera, and other organisms with data available. A pentacyclic triterpene that occurs widely in many PLANTS as the free acid or the aglycone for many SAPONINS. It is biosynthesized from lupane.
