Pueraria Root Extract

Pueraria Root Extract is a standardized botanical ingredient widely used in dietary supplements, functional foods, and formulation research, valued for its high puerarin content and consistent phytochemical profile. Rather than positioning this ingredient as a "treatment," Jiuyuan Biotechnology supplies Pueraria Root Extract strictly as a raw material for industrial and formulation use, aligned with international food and supplement regulatory frameworks. Our extract is produced under full GMP conditions, with batch-to-batch analytical consistency, making it suitable for brands that require stable specifications, documented testing, and long-term supply reliability.

1. Puerarin-Focused Standardization (Not Generic Isoflavones)

Unlike many market offerings labeled only as "total isoflavones," our Pueraria Root Extract is specifically standardized to puerarin, the most studied and analytically identifiable marker compound of kudzu root.

• Clear assay target: ≥30% or ≥40% puerarin (HPLC)
• Suitable for formulations requiring defined functional markers
• Avoids ambiguous "total flavonoid" labeling issues

2. Industrial-Grade Quality Control & Traceability

Each production batch is supported by a complete Certificate of Analysis, including:

• Marker compound assay (HPLC)
• Particle size distribution
• Heavy metals (ICP-MS)
• Microbiological safety (USP standards)

This level of documentation supports brand compliance, import clearance, and downstream regulatory review.

3. Controlled Particle Size for Formulation Compatibility

Standard mesh: 80 mesh (≥95% pass)

Custom milling available for capsules, tablets, or beverage premixes

Ensures uniform blending and dosage accuracy

4. Supply Stability for Long-Term Programs

Raw materials are sourced from established cultivation regions in Shaanxi Province, combined with Jiuyuan's large-scale extraction capacity, ensuring:

• Stable annual supply
• Scalable production volumes
• Reduced procurement risk for contract manufacturing

Pueraria Root Extract contains a complex matrix of naturally occurring plant compounds, primarily:

Isoflavones (Primary Marker Compounds)

Puerarin – the principal isoflavone used as a quality marker

Daidzin

Daidzein

Genistein

Minor derivatives such as hydroxypuerarin and methoxypuerarin

These compounds are commonly studied in food science and botanical research for their antioxidant properties and role in plant-derived functional ingredients.

Other Naturally Occurring Constituents

Triterpenoid saponins

Plant sterols (e.g., β-sitosterol)

Minor coumarin derivatives

Their presence contributes to the overall phytochemical integrity of the extract but is not used as a basis for medical claims.

Based on published laboratory and formulation research, Pueraria Root Extract is generally associated with:

• Antioxidant activity at the ingredient level
• Plant-derived isoflavone content relevant to functional food design
• Use in formulations targeting metabolic and cardiovascular wellness concepts, without implying disease treatment

All functional descriptions are ingredient-level characteristics, not clinical outcomes.
