What Is Eucommia Bark Leaf Extract?
A wonderful botanical resource in traditional health practices, the substance is derived from the leaves of the Eucommia ulmoides Oliver tree. Extracting bioactive components from leaves is an alternative to collecting bark that is both sustainable and renewable.
At high levels, the extract includes:
- Primary marker compound: chlorogenic acid
- Anthocyanins (strong anti-inflammatory agents)
- Geniposidic acid regulates metabolism.
- Immune support polysaccharides
Whether you're making health supplements, functional meals, cosmetics, or cutting-edge feed additives, this multipurpose ingredient may help your applications succeed. The natural integrity of active chemicals is preserved throughout the water-ethanol extraction process, which guarantees maximal bioavailability.

Frequently Asked Questions
Q: What is the difference between Eucommia leaf extract and Eucommia bark extract?
A: The main use of eucalyptus bark has always been to strengthen the muscles and bones. The leaves of the eucommia plant, on the other hand, are rich in flavonoids and chlorogenic acid. This elevates the role of leaf extract as an antioxidant, metabolic regulator, and immune system booster. When opposed to bark stripping, leaf collecting also offers a renewable and sustainable supply.
Q: How is the product's solubility in water?
A: This substance is very soluble in water and has been finely refined. It does not precipitate when added to water-based formulations, liquid supplements, or drinks.
Q: What is the shelf life of the product?
A: When kept correctly, the shelf life may be up to 24 months. To preserve the extract's efficacy, store it in airtight containers in a cool, dry spot that isn't exposed to direct sunlight.
Q: Can you provide customized specifications?
A: Definitely. Particle size modifications, bespoke packaging, and unique Chlorogenic Acid concentrations (ranging from 5% to 98% via HPLC standardization) are all part of our OEM/ODM service offerings. Get in touch with our technical staff so we can go over your unique needs.
Q: What quality documentation do you provide?
A: Each shipment includes a Certificate of Analysis (CoA) with HPLC verification, heavy metal test results, microbiological screening data, pesticide residue reports, and solvent residue analysis. Third-party testing reports are available upon request.
