The Extract Factory is a trusted B2B manufacturer and bulk supplier of high-purity Astragalus Extract, delivering standardized botanical ingredients to nutraceutical, pharmaceutical, and functional food manufacturers worldwide. Sourced from authenticated Astragalus membranaceus roots and processed under rigorous quality management systems, our extract provides consistent levels of bioactive polysaccharides, flavonoids, and triterpene saponins to support immune health, metabolic vitality, and formulation stability at industrial scale.
Botanical Overview & Bioactive Composition
Astragalus Extract is a concentrated botanical preparation derived from the dried roots of Astragalus membranaceus (Fisch.) Bunge, a perennial legume indigenous to the arid and semi-arid regions of northern China. Revered in traditional herbal systems for centuries, the root is now a cornerstone ingredient in modern dietary supplements and adaptogenic formulations.
The therapeutic and commercial value of our extract lies in its rich phytochemical matrix, which includes:
- Polysaccharides: The primary immunomodulatory constituents, standardized between 5% and 20% assayed by UV spectrophotometry.
- Flavonoids: A complex of isoflavones, flavonols, and related phenolics that contribute significant antioxidant capacity.
- Astragalosides (Saponins): Triterpene glycosides widely studied for their adaptogenic, cardioprotective, and metabolic-support properties.
- Amino Acids & Trace Minerals: Nutritional cofactors that enhance the holistic efficacy of the extract in comprehensive wellness formulations.
Sourcing & Raw Material Integrity
We collaborate with established cultivation networks in China’s primary astragalus-growing belts to secure roots that meet pharmacopeial-grade specifications. Upon arrival at our facility, every incoming lot undergoes stringent organoleptic evaluation, botanical identity confirmation, and moisture-content screening. Only roots that pass this multi-point intake protocol advance to extraction, effectively eliminating adulterated, contaminated, or substandard material. This disciplined approach ensures full farm-to-batch traceability and consistent phytochemical profiles for global buyers and regulatory auditors.
Extraction Technology & Manufacturing Process
Our production methodology integrates time-honored botanical processing with advanced separation engineering:
- Selective Extraction: Raw roots are milled and processed under optimized solvent polarity and controlled thermal conditions to maximize the recovery of water-soluble polysaccharides and ethanol-soluble flavonoid fractions.
- Crystallization & Purification: Targeted active fractions undergo precision crystallization, effectively removing insoluble particulates, low-polarity impurities, and unwanted co-extractives. This step materially increases the purity and concentration of marker compounds.
- Concentration, Drying & Milling: The purified concentrate is gently dried and milled into a fine, homogeneous yellow-brown powder with 95%–99% of particles passing through an 80-mesh sieve, ensuring excellent flowability for direct compression, encapsulation, or dry-blending operations.
All processing is conducted within a 100,000-class cleanroom environment to prevent cross-contamination and preserve ingredient integrity.
Comprehensive Quality Specifications
Each production lot is subjected to exhaustive in-house analysis and periodic third-party verification to confirm compliance with international standards for dietary supplements, food additives, and herbal preparations.
