Extraction of Oleanolic acid from Hemsleya Chinensis Cogn.
Formulas containing Oleanolic acid in Food supplements
We found that the oleanolic acid used in health supplements mainly comes from three kinds of plant extracts: Loquat leaf extract, Hemsley Chinensis extract, and holy basil extract.
- Holy Basil powder (leaf) (0.4% Ursolic acid and Oleanolic acid, 2.0 mg)
- Holy Basil supercritical CO2 extract (leaf) (Ocimum tenuiflorum Linn.) (2.5% Ursolic acid and Oleanolic acid, 1.5 mg)
- Loquat Extract (fruit) (providing Ursolic acid, Oleanolic Acid) (Standardized to Ursolic acid Per Serving 125mg)
Oleanolic acid VS Ursolic acid
Oleanolic acid (OA) and ursolic acid (UA) are natural triterpenoids that have a similar chemical structure.
These triterpenoids compounds are known to exist in medicinal herbs and foods.
They have many common pharmacological properties: hepatoprotective, anti-inflammatory, antimicrobial, hypoglycemic, antimutagenic, anti-HIV activity, antioxidant, and antifertility activities.

Biological Activities of Oleanolic Acid

Anti-Tumour/Anti-Cancer Effects
Inhibitory effect of oleanolic acid on hepatocellular carcinoma via ERK-p53-mediated cell cycle arrest and mitochondrial-dependent apoptosis
– by Xin Wang, Hua Bai, etc. Researchers
OA exhibited an inhibitory effect on HCC through induction of apoptosis and cell cycle arrest both in transplanted tumors and in HepG2 cells.
OA induced apoptosis through the mitochondrial pathway, evidenced by inhibition of Akt/mammalian target of rapamycin pathway.
OA induced G2/M cell cycle arrest through p21-mediated down-regulation of cyclin B1/cdc2.
OA demonstrated significant antitumor activities in HCC in vivo and in vitro models. These data provide new insight into the mechanisms underlying the antitumor effect of OA.
In addition, research shows that OA and its derivative Oleanolic acid methyl ester also have effects on breast cancer, lung cancer, bladder cancer, cervical cancer, pancreatic cancer cells…
-
Antimicrobial Activity
OA is expected to possess antimicrobial activity against a wide range of pathogens for it plays a vital role in defending against pathogens in plants.
OA showed moderate activity against Staphylococcus aureus and Bacillus Thuringiensis at 62.5 µg/mL and Escherichia coli, Salmonella Enterica, and Shigella dysenteriae at 31.2 µg/mL minimum inhibitory concentration (MIC).
-
Hepatoprotective Ability
One of the notable bioactivities of OA is the protection of the liver against toxicity and is currently being used as an over the hepatic counter drug in China.
In Wistar albino rats, OA from Flaveria Trinervia was used and had a significant protective effect on ethanol-induced liver toxicity by restoring the hepatotoxic serum marker enzyme levels. This study suggested the antioxidant ability of OA as another possible mechanism of its hepatoprotective ability.
Oleanolic Acid and its derivatives
Oleanolic Acid Clinical Trials
Oleanolic acid (sourced from olive), there are about 500 registered clinical trials, showed it had beneficial effects in clinical trials on chronic kidney disease, diabetes mellitus type 2, and some inflammatory conditions such as arthritis.
Most popular derivatives in clinical trials are bardoxolone methyl (CDDO-Me). CDDO-Me was evaluated in tumor biopsies, and it might be able to play a role in the treatment of chronic kidney disease, it is currently being assessed in effects on hypertension.
