Product Introduction
Chamomile Flavonoid - Premium Natural Plant Extract for B2B Applications
Kang Biotech offers pharmaceutical-grade Chamomile Flavonoid. They have been making natural ingredients well for over 11 years and have been good at extraction technology for over 20 years. Our standardized extract comes from carefully chosen Citrus arantium L. and uses modern water or ethanol extraction methods to get 98% HPLC-verified Apigenin (CAS 520-36-5). We keep full quality control from getting the plants to the final packing. We do this from a 33,000 m² certified building with 9 specialized production lines. Each batch goes thru a lot of tests, such as HPTLC identification, heavy metal screening (ICP-MS), and herbicide residue analysis that looks at more than 400 substances. These tests make sure that the food meets the standards for ISO 9001, ISO 22000, HACCP, Halal, Kosher, and FAMI-QS.
Our ready-stock collection means that we can quickly ship to more than 40 countries in the nutraceutical, functional food, and cosmetics businesses.

Why Choose Our Chamomile Flavonoid Extract?
Bioactivity and production dependability distinguish our product. The extract is useful for antioxidant compositions because to its high ORAC value and free radical scavenging action.
Our product is thermally stable up to 80°C during short processing, unlike ordinary plant extracts. It may be included into pasteurized drinks and hot-fill applications without losing bioactivity.
Supplement makers may guaranty dose accuracy using 98% Apigenin. LC-MS/MS testing ensures pyrrolizidine alkaloids (PAs) are below detectable limits in each production batch, addressing liver safety issues.
We provide micro-encapsulated standard and water-soluble grades. The sepecific formulation allows clear beverage applications at pH 3.0-4.0 and oxidative stress stability.
Our versatile customisation helps your formulation team. We tailor purity, particle size distribution, and carrier systems to your processing needs and applications.

Diverse Industrial Applications
Nutraceutical Brain Health
Chamomile Flavonoid is used in stress-relieving capsules and liquid tinctures for the B2B supplement industry. Apigenin binds GABA-A receptors, facilitating non-drowsy relaxation formulations. Manufacturers like its consistency in hard capsule and softgel delivery techniques.
Skincare Products
High-end cosmetics use our extract in sensitive skin serums and barrier-repair lotions. Flavonoid complex stabilizes complex oil-in-water emulsions at pH 4.5-6.0 and reduces UV-induced erythema. It works well with other active components without precipitation or color deterioration.
Functional Drinking Systems
Our water-soluble grade is used in clean-label herbal teas. The extract retains bioactivity after flash pasteurization and outperforms synthetic counterparts in acidic conditions in oxidative stability.
Nutritional Tablets
Contract manufacturers want low moisture and bulk density for direct compression tableting. Fine powder enables consistent mixing and predictable flow during high-speed encapsulation.
Comprehensive Quality Assurance Protocol
Five essential checkpoints use modern analytical instruments for quality control. HPTLC identification verifies botanical validity and identifies inexpensive plant material adulteration.
HPLC-DAD quantitative analysis ensures batch-to-batch Apigenin-7-glucoside content per formulation parameters. ICP-MS screens for Lead, Arsenic, Cadmium, and Mercury < 0.1 ppm.
Per EC 396/2005 regulations, pesticide residue testing uses GC-MS/LC-MS for approximately 400 chemicals. Microbiological testing guarantee TPCs below 1000 CFU/g and no E. coli or Salmonella.
A complete Certificate of Analysis with traceability is included with every shipment. This helps with regulatory applications and clean-label certification across markets.

Flexible Packaging and Global Logistics
Standard packaging comes in 25 kg fiber drums optimized for industrial handling and long-term storage. We accommodate custom packaging requests including smaller retail-ready sizes, foil-lined bags, and private labeling for your brand requirements.
Small trial orders ship via FedEx for rapid delivery within 3-5 business days. Bulk commercial orders utilize air freight or sea transportation based on your timeline and cost preferences.
Our ready-stock inventory eliminates extended lead times, supporting your just-in-time production schedules. We coordinate directly with your logistics team to ensure proper handling of botanical extracts during international transit.
OEM and ODM services extend to custom specifications, blended formulations, and co-packaged solutions. Your technical requirements for particle size, flow characteristics, or carrier systems receive dedicated support from our R&D team.

FAQ
Q1: Why are total flavonoids and Apigenin content different?
A1: Total flavonoids (UV technique) measure all polyphenolic components, while HPLC quantifies Apigenin. HPLC specification is essential for therapeutic consistency because a 10:1 extract ratio doesn't guaranty high Apigenin levels.
Q2: Does heat processing stabilize the product?
A2: Standard flash pasteurization preserves the extract. Temperature monitoring is recommended for longer heat applications because glycoside hydrolysis can occur over 100°C.
Q3: How do you ensure pyrrolizidine alkaloid (PA) safety?
A3: We use targeted LC-MS/MS screening to ensure PA levels stay below detectable criteria, minimizing hepatotoxicity issues that might affect product safety certifications.
Q4: Does this ingredient operate in clear aqueous solutions?
A4: Our water-soluble grade employs micro-encapsulation technology for clear beverage applications without cloudiness or sedimentation, unlike standard extracts.
Q5: What are the storage requirements and shelf life?
A5: Cool, dark, airtight containers preserve the product for 24 months. Accelerated stability testing under ICH criteria verifies this shelf life.
