Oleanolic acid CAS：508-02-1

First and foremost, Oleanolic acid is a natural pentacyclic triterpenoid extracted from glossy privet fruit, olive leaves and multiple medicinal plants. This bioactive crystalline raw material delivers prominent liver-protective, anti-inflammatory and antioxidant biological activities. For this reason, pharmaceutical factories, nutraceutical brands and cosmetic manufacturers widely adopt this standardized plant extract in diversified production lines.

To start with, this triterpenoid material forms off-white fine crystalline powder with almost no peculiar odor. In addition, it dissolves well in ethanol, chloroform and propylene glycol while barely dissolving in cold pure water. Meanwhile, light-proof sealed cool storage can fully lock its stable biological activity for long shelf life. On the contrary, long exposure to strong high temperature will trigger partial molecular decomposition and weaken core efficacy. Besides that, our finished product reaches 98%–99% HPLC purity and meets pharmacopoeia industrial testing standards.

We select mature glossy privet fruit as stable mass extraction feedstock. Firstly, workers crush and purify raw herbal materials to remove fruit pulp and fiber impurities. Next, low-temperature alcohol reflux extraction separates crude triterpenoid mixtures. After that, repeated recrystallization and fine membrane filtration upgrade finished purity. Furthermore, every finished batch undergoes strict HPLC content and heavy metal inspection. Thus, qualified stable Oleanolic acid is ready for global bulk shipment.

Compared with mixed crude herbal extracts, our purified oleanolic acid holds fixed high triterpenoid content with stable batch consistency. In addition, it integrates liver care, anti-oxidation and anti-inflammation triple effects to simplify multi-ingredient formula design. Moreover, pharmaceutical, food and cosmetic triple grades satisfy medical preparation, health supplement and skincare production separately. Meanwhile, natural plant-derived source avoids chemical synthesis residues for clean-label manufacturing demands.

For instance, it acts as core raw material for hepatitis auxiliary treatment tablets, regulating liver enzyme levels and alleviating liver tissue inflammation.

Blend the crystal powder into liver-protection capsules and anti-aging oral granules to neutralize internal free radicals.

Beyond edible medical usage, this triterpenoid ingredient relieves skin redness, inhibits oxidation and repairs fragile barriers in anti-aging facial essences.
