// Standardised Herbal Extracts — HPLC Verified, Bulk India

Standardised Herbal Extracts: Guaranteed Active Content, Analytically Verified Per Lot

A standardised herbal extract is the format of choice when your formulation or product label requires a guaranteed minimum percentage of a specific active compound. Unlike ratio extracts — which concentrate the whole plant without specifying individual compound content — a standardised extract is analytically verified to contain a defined minimum level of a target active in every production lot: 95% curcuminoids, 5% withanolides, 20% ginsenosides, 80% silymarin, 50% chlorogenic acid.

This is the specification required for evidence-based supplement formulation, regulatory-aligned label claims, clinical dose matching, and supply chains where incoming quality control requires a verifiable active compound guarantee. This collection covers standardised extracts across all botanical categories Herbuno supplies. New products are added continuously — use the filters to find your specific ingredient and standardisation level.

HPLC vs UV standardisation — know the difference: The analytical method used to verify active content determines the specificity of the claim. HPLC (High-Performance Liquid Chromatography) separates and quantifies individual compounds — a "5% withanolides by HPLC" claim means withanolide molecules were individually identified and measured. UV spectrophotometry measures total absorbance at a specific wavelength — less specific, susceptible to interference from co-extractants, and may overstate true active content. Always confirm the analytical method on the CoA before accepting a standardised extract specification. All standardised extracts in this collection use HPLC or equivalent specified methods — stated on each product CoA.
Ratio extract vs standardised extract — choosing the right specification: If your formulation does not require a specific active compound percentage on label, a full-spectrum ratio extract is often more cost-effective and appropriate. If your label claims a specific active level, your regulatory submission requires quantified compound data, or your clinical dose is derived from a specific active percentage, a standardised extract is the correct specification.

Built for Evidence-Based Formulation and Label Claim Support

🧪

Supplement Brands With Active Compound Label Claims

Products making label claims referencing a specific active — "500mg Ashwagandha standardised to 5% withanolides," "400mg Curcumin 95%," "200mg Green Tea standardised to 50% EGCG" — require a standardised extract with HPLC-verified active content on the CoA to support the claim. This is the format for regulatory-aligned formulation in US (FDA cGMP), EU, UK, and Australian markets.

Clinical & Evidence-Based Formulation

Formulations designed to match clinical trial doses require the same active compound percentage as the studied material. If a clinical trial used curcumin at 95% curcuminoids, your formulation requires a 95% curcuminoids standardised extract to deliver an equivalent dose. Standardised extracts are the only format where dose-response matching to published research is verifiable and defensible.

Contract Manufacturers & Private Label Producers

Incoming quality control for supplement manufacturing requires active compound verification on each incoming lot — not a generic reference CoA. Standardised extracts from this collection include per-lot HPLC assay as standard, providing the documentation required for incoming QC records, batch manufacturing records, and product release protocols in certified manufacturing environments.

// Common Questions

Standardised Extracts — Frequently Asked Questions

What does "standardised to X%" mean on a herbal extract CoA? +
It means the finished extract has been analytically tested and confirmed to contain not less than X% of the stated active compound by the stated analytical method. "NLT 5% withanolides by HPLC" means the lot was tested, withanolide molecules were individually identified and quantified by HPLC, and the result was 5% or above. This is a per-lot guarantee — not a specification from a previous batch or a reference standard applied across multiple production runs. Every lot shipped carries its own CoA with its own assay result.
What is the difference between HPLC and UV standardisation? +
HPLC separates and individually quantifies specific compounds — it is compound-specific and highly precise. UV spectrophotometry measures total absorbance at a wavelength associated with the target compound class — it is less specific and can be inflated by co-extractants that absorb at the same wavelength. A curcumin extract "standardised to 95% by UV" may contain significantly less true curcuminoid content than one "standardised to 95% by HPLC." For regulatory submissions and clinical dose matching, HPLC is the required and accepted standard. All standardised extracts in this collection use HPLC or equivalent compound-specific methods — confirmed on the CoA.
Can I request a custom standardisation level not listed in the catalogue? +
Yes — for many botanicals, custom standardisation targets are achievable subject to MOQ and lead time. Contact us with the botanical, target active compound, required percentage, and annual volume estimate. We will confirm feasibility, MOQ, and indicative pricing. Custom standardisation typically requires a minimum batch size and longer lead time than standard catalogue products.
What is the MOQ for standardised extracts? +
Standard MOQ is 1 kg for most standardised extracts in this collection. Samples with per-lot CoA are available before bulk commitment. For high-standardisation grades (e.g. 95% curcuminoids, 98% silymarin) MOQ may be higher — contact us for specific products. Export documentation is prepared as standard for all markets.
