Raw Material: Botanical Origin & Sourcing

Our Astragalus roots are sourced from established GAP cultivation bases, primarily Gansu Longxi, Inner Mongolia Guyuan, and Northern Shaanxi (Yulin) — regions recognized for the long-standing production of Astragalus membranaceus (Fisch.) Bunge and A. membranaceus var. mongholicus (Bunge) Hsiao dry roots.

Incoming raw material is screened through three checkpoints:

1. Origin verification: long-term partner farms with full traceability records.

1. Visual grading: removal of insect damage, mold, hollow hearts, and over-ligneous sections.

1. Pre-acceptance analysis: water content, total ash, and sulfur dioxide residue tested before release to the production line.

Crude Powder: Low-Temperature Milling

For buyers who require raw powder as part of a formula base, our dedicated low-temperature milling workshop operates under 25 °C to protect heat-sensitive components.

• Particle size: 60–200 mesh, customizable per order.

• Contact surface: stainless steel throughout.

• Packaging: food-grade PE inner bag with optional aluminum foil or fiber drum outer layer.

Extract: Specifications & Production

Two main production routes cover the most common buyer requirements:

Custom specifications (e.g., Astragaloside IV 98% monomer, or atypical ratios) are evaluated on a project basis.

Quality Control & Documentation

In-house laboratory equipment: HPLC, UV, GC, TLC, atomic absorption spectroscopy, and microbiological workstations. Every batch of finished extract is released against the following reference limits:

• Moisture: ≤ 5%

• Ash: ≤ 8%

• Heavy metals: total ≤ 10 ppm (Pb ≤ 2, As ≤ 1, Hg ≤ 0.1, Cd ≤ 1)

• Pesticide residues & microbiology: per USP, EP, ChP, or buyer-specified standard

• Residual solvents: compliant with ICH Q3C and destination-market regulations

Each shipment is accompanied by a Certificate of Analysis (COA). Third-party re-testing at SGS, Intertek, or a buyer-designated lab is welcome. Retained samples are kept for a minimum of 24 months.
