Products Description

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.

Key Features

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

 

Phytochemical Composition

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.

 

Functional Attributes

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.

The core issue with commodity puerarin: Many suppliers report isoflavone content using non-specific UV spectrophotometry. This method cannot distinguish puerarin from other isoflavones or even non-isoflavone UV-absorbing compounds. The result is systematically inflated potency numbers that collapse under HPLC scrutiny.

FAQ

Q1: What is the difference between puerarin and total isoflavones in Pueraria Root Extract?

Puerarin is a single, specific isoflavone compound - daidzein-8-C-glucoside - and it's the dominant bioactive in kudzu root. "Total isoflavones" is a broader measurement that includes puerarin plus daidzin, daidzein, formononetin, and other minor isoflavones. A product standardized to "40% total isoflavones" will contain less puerarin than a product standardized to "40% puerarin." Always clarify which marker your supplier is measuring - and by which method.

Q2: Is Pueraria Root Extract safe for women with estrogen-sensitive conditions?

Puerarin and kudzu isoflavones act primarily as selective estrogen receptor beta (ERβ) agonists at physiological doses. ERβ activation is associated with cardiovascular and bone tissue effects rather than the proliferative effects linked to ERα in reproductive tissue. However, women with hormone-sensitive conditions should consult a healthcare provider before use. As a B2B ingredient supplier, we recommend that our customers include appropriate label disclaimers and consult regulatory counsel for finished product claims.

Q3: Can Pueraria Root Extract be used in functional beverages?

Yes - our water-soluble Puerarin 40% grade dissolves cleanly in aqueous systems with good clarity. It is stable at standard beverage processing temperatures (below 80°C) and shows acceptable stability at pH 3.5–7.0. For clear beverage applications, we recommend a trial dissolution test at your target pH and temperature before finalizing the formula.

Q4: What is the recommended dosage for supplement formulations?

Dosage varies by application. Published clinical studies on isoflavone supplementation for menopausal symptoms typically use 40–80 mg total isoflavones per day. Cardiovascular and neuroprotective research on puerarin specifically has used doses ranging from 50–200 mg puerarin per day. We recommend working with a formulation specialist to align your dose with the relevant clinical literature for your specific health claim.

Q5: How do you ensure batch-to-batch consistency?

Consistency starts upstream. We source from dedicated cultivation bases with controlled agronomic conditions - not open commodity markets where glucoside content varies unpredictably by season and origin. Every incoming raw material lot is tested before extraction begins. Finished batches are released only after full HPLC potency confirmation against certified reference standards. Retained samples are archived for 24 months, enabling full retrospective traceability.

Q6: Do you offer custom specifications or white-label packaging?

Yes. We offer OEM/ODM services including custom puerarin specifications (beyond our standard range), custom particle size, encapsulation into capsules or sachets, and private-label packaging. Minimum order quantities for custom work start at 25 kg. Contact our technical team to discuss your project requirements.

Q7: What certifications are required for selling in the EU market?

For EU dietary supplement distribution, your supplier should hold at minimum ISO 22000 and FSSC 22000 for food safety, plus EU Organic certification if you're making organic claims. Additionally, note that high-dose puerarin products may fall under EU Novel Food Regulation (EU) 2015/2283 in some member states. We can provide regulatory support documentation to assist with your compliance review.

Q8: What is your lead time and minimum order quantity?

For stocked standard specifications (Puerarin 40%, 60%, 80%; Total Isoflavones 40%), commercial lead time is 2–3 weeks after order confirmation. Sample orders (1–500 g) ship within 3–5 business days. For pharmaceutical-grade Puerarin 98% or custom specifications, lead time is 4–6 weeks. MOQ for commercial orders is 25 kg; samples available from 100 g.
