Astragalus Root Extract Powder

Astragalus Root Extract Powder – Standardized Botanical Extract for Immune & Cellular Health Formulations

Shaanxi Hongda Phytochemistry Co., Ltd. supplies Astragalus Root Extract Powder to be used as a pharmaceutical grade product extracted from the dried roots of Astragalus membranaceus (var. mongholicus) with a specification of 0.3%-98% Astragaloside IV and 10%-70% Polysaccharides. This extract has been tested by HPLC/UV with a delivery cycle of only 3-7 working days. Removes the batch-to-batch potency variation seen in raw root material. Hongda provides B2B buyers with reliable large-scale supply of standardised astragalus extract with yearly production of 3,000 tons, 100,000-level purification workshops and Certifications including KOSHER, HALAL, BRC, ISO9001, ISO22000 and ORGANIC.

What Is Astragalus Root Extract Powder?

Our product is a concentrated botanical substance derived from the dried roots of Astragalus membranaceus (Fisch.) Bunge, a plant commonly used in Traditional Chinese Medicine called Huang Qi. The raw roots are extracted with water or ethanol and spray dried to give a fine, brown-yellow powder.

This technique concentrates two essential bioactives: 1) Astragalosides (mostly Astragaloside IV, CAS 83207-58-3) for cellular and telomere health and 2) Astragalus Polysaccharides (APS) for immunological regulation. Extraction ratios can be 10:1 or higher, even 20:1, allowing formulators to provide efficacious dosages at modest capsule fill weights.

The extract addresses three actual supply-chain issues that raw root cannot: variable potency between crop harvests, poor bioavailability from intact cellulosic fibre, and increased microbial risk from unprocessed root material.

Third-Party Test Report

Hongda ships every batch with documented analytical test support. We have our own in-house SGS standard laboratory and authorised third party organisations such as SGS and Eurofins.

Tests carried out before despatch include:

· Active markers: Astragaloside IV and Polysaccharide content by HPLC and UV

· Heavy metals: Lead, arsenic, cadmium, mercury 

· Pesticide residues: Multi-residue panel of EU and US standards

· Microbiological: Total plate count, yeast, mould, pathogens

· Physical: Particle size, bulk density, moisture loss on drying 

Complete test records are available for each lot number upon request.

Astragalus Root Extract Powder Advantages

Not simply concentrated but standardised.A ratio extract (like 10:1) is telling you volume, not potency. Our standard grades guaranty defined active percentages – so your completed product provides consistent results, batch after batch.

Wide range of specifications.0.3% Astragaloside IV for general wellness blends, or high-purity isolates of 98% for clinical or cosmeceutical application – you choose the spec your composition requires.

We have organic choices.Organic quality extract is obtained from NOP/EU certified agricultural bases, extracted on specialised organic lines using certified organic ethanol or water, without risk of cross contamination.

Verification of clean label polysaccharides.Polysaccharide content is confirmed via enzymatic hydrolysis or C-isotope carbon testing to separate Astragalus-specific APS from maltodextrin or generic starch fillers – an important consideration for clean-label and premium product lines.

Low microbial burden.The spray drying process and regulated environment in a 100,000-level cleanroom greatly lower the danger of microbial contamination compared to root powders, which helps to fulfilll the GMP criteria for nutritional supplements.

Application Scenarios 

Dietary Supplements (Capsules & Tablets)

The powder demonstrates good compressibility and uniform flow properties. This decreases excipient loading in tablet compression and enables precision dosing of Astragaloside IV for immune-support and anti-aging SKUs.

Functional Beverages & Ready Mixes

Water-soluble polysaccharide standardised grades will dissolve cleanly in liquid matrices without precipitation. They are stable over a range of pH values and they tolerate thermal pasteurisation without active loss.

Topical Formulations (Cosmeceuticals)

Astragaloside IV mid-range purity grades are utilised in anti-ageing serums and skin barrier lotions. The extract is stable in oil-in-water emulsions and has antioxidant activity without changing the product viscosity or sensory profile.

Important formulation note: High purity Astragaloside IV (>10%) has decreased water solubility. These grades may require lipid-based carriers or solubilization agents in the liquid formulations.

Production Process

Hongda’s production is based on a tested multi-stage extraction workflow:

Raw Material Selection → Cleaning & Pre-treatment → Water/Ethanol Extraction → Filtration & Concentration → Spray Drying → Sieving & QC Testing → Packing

The astragalus roots used are raw and come from Hongda’s own base for growing Chinese medicinal herbs, which is overseen by skilled agronomists. This allows traceability from the soil to the shipment.”

The extraction step is carried out with aqueous or ethanol systems, depending on the objective marker – water extraction for polysaccharide-rich grades and ethanol extraction for high Astragaloside IV concentration. The final spray drying step retains the active content and results in the typical free-flowing brown-yellow powder.

All production is done in a 100,000 level clean room, following cGMP aligned protocols.

FAQ

Q1: What is the difference between a ratio extract and a standardized extract?

Q: What is a 10:1 ratio extract? A: 10kg of root makes 1kg of extract, although active content will change from harvest to harvest. So, a standardised extract means you have a certain active percentage (say 0.5% Astragaloside IV), so you have consistent performance from the product regardless of what crop season it is.

Q2: Does the powder dissolve in water?

A. The polysaccharide standardised grades are normally water-soluble and suitable for use in beverage applications. Astragaloside IV of high purity (>10%) is poorly soluble in water and may require lipid-based carriers in liquid systems.

Q3: How to keep the powder during production?

A. The powder is hygroscopic. Maintain manufacturing settings below 45% relative humidity. Use moisture barrier packaging of aluminium foil and add silica desiccants immediately after drums are opened. Storage: Store in a cool, dry place away from direct light.

Q4: Is it confirmed that the polysaccharide content is not derived from maltodextrin?

A: Oh, for sure. We use either enzymatic hydrolysis analysis or C-isotope carbon testing to identify Astragalus-native polysaccharides from additional starch fillers. Documentation for clean-label compliance is available.

Q5: Do you supply organic certified extract?

Yes. Organic grades are sourced from NOP/EU farms and are extracted in dedicated organic production lines using certified organic solvents. Each batch comes with certificates.

Q6: What paperwork do you provide for import/regulatory purposes?

A: We give COA, MSDS, Test reports by SGS/ Eurofins, phytosanitary certifications and specification documents. Additional documentation such as nutrition labels, natural statements or optical rotation studies can be arranged according to your market needs.
