Astragalus Extract Powder

Astragalus Extract Powder is a standardized botanical ingredient derived from the dried roots of Astragalus membranaceus (Fisch.) Bunge., a leguminous plant widely used in traditional herbal systems and modern nutraceutical formulations. The extract is manufactured under controlled conditions to concentrate astragalus polysaccharides, astragalosides, and flavonoids, ensuring consistent composition and reproducible performance across batches.

Jiuyuan Biotechnology supplies Astragalus extract in multiple standardization options, including polysaccharide-based extracts, high-purity astragalosides, and ratio extracts, to meet the formulation requirements of dietary supplements, functional foods, and cosmetic applications.

Our raw Astragalus roots are sourced from GAP-managed cultivation areas in Gansu and Inner Mongolia, regions recognized for favorable soil composition and climatic conditions that support polysaccharide and saponin accumulation. Each batch of raw material undergoes botanical identity verification prior to processing.

Appearance: Yellow-brown to grey-white powder
Solubility: Water soluble (polysaccharide-based grades)
MOQ: 25 kg
Shelf life: 24 months (sealed, cool & dry storage)

Standardization Options

Astragalus Polysaccharides: 10%–30% | 30%–50% | 50%–70%

Astragalosides: 0.3%–1% | 5%–20% | 50%–98%

Extraction Ratio: 4:1, 5:1, 10:1

Different specifications are designed for distinct functional positioning, dosage formats, and regulatory strategies.

Astragalus root contains multiple naturally occurring compound classes. The finished extract will not necessarily preserve every constituent in the same proportion as the raw root, which is why marker selection must reflect the actual product and process.

Marker Selection Should Follow the Commercial Goal

Different projects may require different quality approaches:

● Ratio extract: Suitable where the desired profile is process-defined rather than marker-standardized.

● Astragaloside-focused extract: Relevant where an agreed saponin marker is commercially necessary.

● Polysaccharide-focused extract: Requires a clearly stated test method because polysaccharide assays are method-dependent.

● Multi-marker or fingerprint approach: May be useful for sophisticated quality programs seeking a broader profile assessment.

No single marker can fully represent the entire botanical matrix. The most defensible specification is the one that matches the raw material, process, product format, and intended market.

Jiuyuan Biotechnology manufactures Astragalus Extract Powder under a fully controlled, cGMP-compliant production system, integrating advanced separation, sterilization, and particle engineering technologies to ensure purity, microbiological safety, and batch-to-batch consistency.

Step-by-Step Process Flow

1. Raw Material Selection & Botanical Verification
Premium Astragalus membranaceus roots are sourced from GAP-managed farms and botanically authenticated to ensure correct species and plant part prior to processing.

2. Controlled Aqueous / Hydro-Ethanolic Extraction
Extraction is performed under optimized temperature and time parameters to efficiently release polysaccharides and saponins while minimizing degradation of heat-sensitive components.

3. Plate-Frame Filtration (Primary Clarification)
The extract solution undergoes plate-frame filtration to remove insoluble plant residues and coarse impurities, significantly improving extract clarity and downstream processing efficiency.

4. Disc Centrifuge Separation (Fine Purification)
A high-speed disc-type centrifugal separator is applied for fine clarification, enabling efficient removal of suspended solids and ensuring a high-transparency extract liquor, which is critical for stable standardization.

5. High-Temperature Short-Time (HTST) Sterilization
To ensure microbiological safety without compromising active compounds, the clarified extract is treated via high-temperature short-time sterilization, effectively reducing microbial load while preserving functional integrity.

6. Concentration & Standardization
The sterilized extract is concentrated under controlled conditions and adjusted to target specifications for polysaccharides or astragalosides, ensuring consistent active content across production batches.

7. Spray Drying
The standardized liquid extract is converted into a fine powder using spray drying technology, producing a uniform particle structure with good solubility and flowability.

8. Dry Granulation (Optional)
For customers requiring improved bulk density, reduced dusting, or specific particle size distribution, dry granulation is applied. Granulated products can be customized within 8–60 mesh, depending on formulation needs.

9. Sieving, Metal Detection & Packaging
Final products undergo sieving, metal detection, and controlled packaging to ensure physical safety and compliance with international quality standards.

10. Batch Testing & COA Release
Each batch is tested in Jiuyuan's in-house laboratory using UV and/or HPLC methods, followed by full COA issuance before release.

Why This Process Matters for Formulators

• Plate-frame filtration + disc centrifugation ensure extract clarity and stable assay results
• HTST sterilization provides microbiological safety without overprocessing
• Dry granulation capability supports capsule filling, sachets, and instant powder applications

Full process control supports regulatory documentation and long-term supply consistency

Each production batch is tested in Jiuyuan's in-house analytical laboratory.

Typical QC Parameters:

• Active compound assay (UV / HPLC)
• Particle size & moisture
• Ash content
• Heavy metals (Pb, As, Hg, Cd)
• Microbiological limits (TPC, Yeast & Mold, Pathogens)

Full documentation is available, including COA, MSDS, and traceability records, supporting regulatory compliance in the US, EU, and other global markets.

Astragalus extract is commonly incorporated into botanical formulas and daily wellness concepts. Actual inclusion levels should be developed by the finished-product manufacturer based on formula design, sensory requirements, regulatory review, and applicable safety assessment.

Formulation Note

Astragalus extract can have a distinctive earthy and slightly bitter root profile. In consumer-facing products, this is often managed through:

● Fruit flavours or warm-spice profiles

● Sweetener systems appropriate to the target market

● Encapsulation or coating strategies where suitable

● Lower-dose, multi-botanical combinations

● Dry formats rather than clear ready-to-drink products when sensory masking is limited

A sample that performs well in water may behave very differently in a gummy, protein blend, effervescent tablet, or compressed tablet. Finished-product trials remain essential.
