High-Purity Carnosic Acid Powder - Natural Antioxidant Extract for Nutraceutical & Food Preservation Solutions
Xi'an Jiayuan Bio-tech Co., Ltd., the company was created in April 2002, with registered capital RMB 30 million, is a professional manufacturer of medicinal grade Carnosic Acid Powder from rosemary plant (Rosmarinus officinalis). Two GMP-standard production lines and 30 skilled technicians provide quality control at our plant. We are ISO9001-certified and a Shaanxi high-tech enterprise. We provide goods with HPLC purity up to 95% and superior antioxidant stability over synthetic alternatives. We address industrial concerns like food system lipid oxidation and nutraceutical formulation oxidative stress with our approach.
What Is Carnosic Acid Powder?
It is a diterpene phenolic compound from rosemary leaves with the formula C20H28O4, molecular weight 332.43, and CAS number 3650-09-7. This natural antioxidant scavenges free radicals and chelates metals better than BHT or BHA.
Reduces lipid peroxidation via hydrogen donation and singlet oxygen quenching. Despite thermal damage during food preparation, it retains antioxidant activity at 240 °C in commercial applications.
Our brownish-yellow powder form is provided for convenient inclusion into oil-based matrices and encapsulation systems. The lipophilic property of the chemical facilitates better incorporation into lipid-rich formulations where water-soluble antioxidants cannot.
Why Choose Us?
Since 2002 we have been a direct manufacturer. No middleman markup, consistent lot to lot. We have a technical staff of 30 people to provide specific extraction ratios and co-processing services such as spray drying or micronization.
Flexible MOQ (1kg) enables R&D teams to test numerous vendors effectively. We manage urgent requests without sacrificing quality with 80 personnel handling synchronised manufacturing schedules.
Shaanxi is the centre of production of Chinese herbs, and we are geographically privileged there, with the opportunity to track our ingredients back to certified organic farms. This vertically integrated solution decreases the lead times and contamination hazards associated with multi-supplier chains.

Functions
This extract has biological activity aimed at neuroprotection and cardiovascular health. It triggers the Nrf2-ARE antioxidant response pathway, which up-regulates endogenous antioxidant enzymes, including superoxide dismutase and glutathione peroxidase.
Clinical study has shown that it can pass the blood brain barrier, providing protection against neuroinflammation and cognitive impairment. It inhibits the enzymes alpha-glucosidase and lipase which is good in metabolism for healthy blood sugar and lipids.
The chemical tackles formulation issues for producers with product rancidity. Its synergistic activity with tocopherols increases the oxidative stability index (OSI) of oils by up to 300% in comparison to vitamin E alone.
Scope of Application
1. Functional Food & Beverages (B2B) Incorporated in high-PUFA oils, meat products and baked items to improve shelf life without synthetic chemicals. Standard dose is 200-1000 ppm depending on fat content.
2. Dietary Supplements (B2C) - Created in cognitive health capsules, anti-aging softgels and sports nutrition products. Liposomal delivery or conjunction with piperine improves its bioavailability.
3. Cosmeceuticals (B2B): Used in anti-aging serums and UV protection formulations. It inhibits photo-oxidation of skin lipids and lowers MMP-1 expression and collagen breakdown more efficiently than ascorbic acid derivatives.
Quality Control
In our ISO-certified laboratory, we do multi-stage testing on every manufacturing batch. Active compounds content confirmed by HPLC analysis. Pesticide residues screened by gas chromatography <0.01 mg/kg (below limitations of the European Union).
Microbial tests : Total plate count <1000 CFU/g No presence of E.coli and Salmonella Heavy metal contents (Pb, As, Cd, Hg) are confirmed by ICP-MS technique, under pharmacopoeia thresholds.
ICH stability testing demonstrates the product is stable for 24 months when kept at temperatures below 25°C in sealed aluminium foil bags.

FAQ
Q: What is the difference between rosmarinic acid and carnosic acid?
A: Carnosic acid is oil soluble and heat stable and so suitable for oil based systems. Rosmarinic acid is water soluble and more appropriate for use in drinks or topical gels.
Q: Can it be used to replace synthetic antioxidants on food labels?
A: Sure. It will be listed as "rosemary extract:on the label to suit clean-label regulations, and it beats BHA/BHT in thermal stability testing.
Q: What is the recommended storage condition?
A: Store in a cool, dry area, under 25°C, protected from light. Refrigeration preserves potency but may produce transient clumping, which is rectified by careful mixing.
Q: Does it work for vegan and kosher certification?
A: Sure. We extract using non-animal solvents and have evidence for kosher and vegan claims.
