| Hazard Information | Back Directory | [Description]
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. | [Chemical Properties]
White Solid | [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. | [Occurrence]
The ingredient is mainly extracted from the leaves of Olea europaea and Viscum album L. Besides, it is found in the fruit of ligustrum lucidum ait, the whole grass of swertia mileensis t.n.he et w.l.shi, s. mussotii franch, the leaves and roots of astrantia major, the root bark and stem bark of aralia chinensis, the roots of hemsleya macrosperma c.y.wu , the roots of hemsleya amabilis diels, and the roots of hemsleya chinensis cogn. There is a long history in the herb and fruit which contain oleanolic acid. They play an important role in the treatment of various diseases. Oleanolic acid may be the most effective component in various Chinese medicines. | [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. | [Uses]
A triterpenoid known for its anti-inflammatory properties, is commonly present in several medicinal plants. | [Definition]
ChEBI: A pentacyclic triterpenoid that is olean-12-en-28-oic acid substituted by a beta-hydroxy group at position 3. | [Indications]
It is included in the Pharmacopoeia of the People’s Republic of China (Part 2, volume 3), the British Pharmacopoeia (2017), and the European Pharmacopoeia
(8.7th ed.).
It is mainly used for the adjuvant treatment of acute infectious icteric hepatitis
and acute and chronic hepatitis. It also can be utilized in psoriasis, rheumatoid
arthritis, nephritic edema, ascites, stomach with turbid, metrorrhagia, bruises, carbuncle, soreness and weakness of the waist and knees, fetal irritability and so on. | [General Description]
Oleanolic acid is a hydroxyl pentacyclic triterpenoic acid (HPTA), which exhibits antibacterial, antitumor and antileishmanial activity. | [Biochem/physiol Actions]
Triterpenoid isolated from medicinal plants. Antitumor and hepatoprotective agent. Oleanolic acid has therapeutic potential for neurodegenerative diseases. | [Pharmacology]
Liver protection: Pretreatment of 100?mg/kg once a day for 3?days can protect the
liver and decrease the activity of enzymes. It achieves by increasing the amount
of metallothioneins and liver glucoside transferases to prevent glutathione emptying, to inhibit several subtypes of P450 oxidase, and to prevent combination with
toxic substances.Antimicrobial and antiviral effect: Oleanolic acid may inhibit the proliferation or
production of NO induced by interferon or in the macrophages by competitively
binding to the enzymes necessary for the growth and reproduction of microorganisms or virus and play an anti-inflammatory and antiviral role. EC50 of HIV-1-
infected H9 cells is 3.4?mol/L.Effects on metabolism of glucose and lipid: The treatment of 50–100?mg/kg for
4?days achieves the glucosidase activity inhibition, reduction of glucose absorption,
inhibition of glycogen phosphorylase, activation of glycogen synthesis, inhibition
of protein tyrosine phosphatase 1B, regulation of insulin signaling pathway, and
increase of insulin sensitivity, and it may also be achieved by inhibiting the transport
of glucose from the stomach to the intestine and transport activity of intestinal villi.
200?mg/kg suspension administrated by gavage for 4?weeks decreases the level of
triglycerides, cholesterol, and β-lipoprotein in high-fat animal, and it contributes to
increased platelet swimming rate and decreased blood viscosityEffects on immunologic function: 60?mg/kg intraperitoneal injection may regulate the immune system by inhibiting type I allergic reaction, promoting proliferation of lymphocyte and inhibiting enzyme C-3? in the traditional complement
pathway.Antioxidant effect: It fights against lipid peroxidation by scavenging free
radicals.Other functions: 10–5?mol/L oleanolic acid may inhibit the activity of DNA ligase
I active site. It exerts anticancer and anti-mutation effects, and IC50 value is2.2×105
?mol/L in inhibiting ornithine decarboxylase (ODC) induced by external
TPA at the transcriptional level. Oleanolic acid in polyvinylpyrrolidone suspension
at the dose of 16?mg/kg by intragastric administration for 30?days also reversibly
decreases quality and exercise capacity of mouse sperms.It is reported that it is consistent with the single compartment model, or noncompartmental model, and may be distributed in the compound in accordance with
the two compartment models. Eventually, it will be eliminated by P450 oxidase
in the liver. | [Clinical Use]
It is reported that contrast with Western medicine, the 60~90?mg/d oleanolic acid
tablets supplemented with vitamin B can treat acute and chronic hepatitis, with
effective rates of 94.4% and 69.81%, respectively, in clinical results. It has been
listed on the drug manual as adjuvant therapy for acute and chronic hepatitis. | [References]
