- Introduction: Oleanolic acid or oleanic acid is a naturally occurring pentacyclic triterpenoid with the formula of C30H48O3. It was found in the non-glyceride fraction of olive pomace oil and is widely distributed in food and plants where it exists as a free acid or as an aglycone precursor for triterpenoid saponins, in which it can be linked to one or more sugar chains. It is biosynthesized from lupane. It can rearrange to the isomer, ursolic acid, or be oxidized to taraxasterol and amyrin. Oleanolic acid and its derivatives possess several promising pharmacological activities, such as hepatoprotective effects, and anti-inflammatory, antioxidant, or anticancer activities.

- White Solid
- 9.4 Physical properties
- Appearance: Olea europaea exists in white needle crystal with ethanol or methanol. Melting point: It melts at 306–310?°C. Solubility: The ingredient is insoluble in water. Specific optical rotation: Polarized light rotates +83.3° when it passes through chloroform with concentration of 6?mol/L.
- 9.5 History
- The chemical formula was first identified in 1918. In 1960, Khastgir purified the compound for the first time. Corey identified the structure of oleanolic acid in 1993.
Now the compound has been made into a drug and is being marketed in China. As early as 2002, the tablet form of oleanolic acid was listed. In 2010, capsule preparations came into the market, and to date, there is no other listed preparation. Sanofi treated it as antiulcer and NSAIDs candidate in abroad.
Although it has anti-inflammatory and anti-ulcer effects, Sanofi stopped the study of developing oleanolic acid into a drug in 1989.
