Standardised Herbal Extracts & High-Purity Botanical Compounds — India
From Defined Active Extracts to Isolated Botanical Compounds: Three Grades, One Collection
A standardised herbal extract is an extract verified by HPLC or UV to contain a defined minimum percentage of a target active compound or compound class. Unlike ratio extracts, the specification is analytical — not descriptive of the concentration process. Each lot is tested against the stated standard before release, with the result documented on the CoA.
This collection spans three distinct grades of botanical purity: traditional standardised extracts, purified concentrates with very high active content, and isolates derived from botanical sources at 90% or above single-compound purity. All three grades serve different formulation purposes and carry different analytical requirements.
Standardised Extract
5–70%
Defined Active by HPLC
Botanical extract with a guaranteed minimum percentage of a target compound or compound class, verified per-lot by HPLC or spectrophotometric assay. The mainstream specification for evidence-based supplement formulation where a specific active drives the label claim.
Ashwagandha 5% withanolides · Boswellia 65% boswellic acids · Green Tea 50% polyphenols · Grape Seed 70% proanthocyanidins · Silymarin 70% · Andrographis 10% andrographolide
Purified Concentrate
70–89%
High-Purity Single Compound Class
Highly refined botanical extract where a single compound class has been concentrated to 70–89% of the finished powder by chromatographic or recrystallisation processing. Retains botanical derivation; functions at much lower dose weights in formulation.
Curcumin 95% curcuminoids · Piperine 95% · Quercetin 95% (flavonoid fraction) · Grape Seed 95% proanthocyanidins · Beta-sitosterol 40–95%
Isolate / Near-Isolate
90–99%
Single Compound, Botanical Origin
A purified single compound at 90% purity or above, derived from a botanical starting material via multi-step processing. These are functionally purified compounds, not conventional extracts. Appropriate for precise-dose formulations, research applications, and finished products where compound identity, not botanical matrix, is the specification goal.
Berberine HCl 95% · Resveratrol 99% · Huperzine A 98% · Rutin 95% · Diosmin 90% · Quercetin 98% · Indole-3-Carbinol 98%
How to read the CoA for this collection: Every product in this collection ships with a per-lot CoA including the HPLC or UV assay result for the stated active — not a reference document carried across batches. The assay result tells you the actual measured percentage from your specific lot. For isolate-tier products (90%+), the CoA also states purity method and any residual solvent data where applicable. For compounds with phytoestrogenic activity (resveratrol, daidzein, genistein, quercetin), the CoA specifies the compound form; evaluate suitability in hormone-sensitive applications before formulating. For diosgenin-containing products: botanical diosgenin does not convert to hormones in the body — it is a steroidal saponin used as a research material and cosmetic ingredient, not a precursor compound in finished supplement formulations.

Who This Collection Serves
Supplement Formulators, Research Teams & Precision Ingredient Buyers
Standardised extracts and high-purity botanical compounds are the ingredient specification of choice when a finished product's label claim, clinical dossier, or formulation brief requires a confirmed minimum level of a specific active. Herbuno supplies this range direct from India, with per-lot HPLC assay documentation as standard across all three purity tiers.
Evidence-Based Supplement Brands
Formulating products where the label states a specific active content — withanolides, curcuminoids, boswellic acids, ginsenosides. Standardised extracts are the correct specification: per-lot HPLC assay confirms the minimum stated on label is present in every batch. CoA phrasing for label claim support: "standardised to contain not less than X% [active] by HPLC."

Per-Lot CoA
Capsule Grade
Research & Development Teams
Sourcing isolate-tier material (95%+ single compound) for bench formulation, stability studies, bioavailability testing, and compound evaluation. High-purity botanical isolates — berberine HCl, resveratrol, huperzine A — allow precise dose-response evaluation without the compound matrix variability of lower-purity extracts. Samples with CoA available before bulk commitment.

Contract Manufacturers & White-Label Producers
Building formulations for brands requiring specific active guarantees. Standardised extracts allow you to back your customer's label claim with documented supplier-level assay data. Purified concentrates (curcumin 95%, piperine 95%) are used at low inclusion rates — precise dosing in compact capsule formats without bulking agents.

Cosmetic & Dermatology Formulators
High-purity botanical actives for topical applications — resveratrol, quercetin, rutin, and diosmin are used in cosmetic formulation for their roles in skin firmness and vascular support applications. Verify INCI name, solubility profile, and regulatory status for your target market. These compounds may be eligible in qualifying formulations under relevant cosmetics regulations.

Common Questions
Frequently Asked Questions
What is the difference between a standardised extract and an isolate?
+
A standardised extract is a botanical extract verified by HPLC to contain a defined minimum percentage of a target active within a complex plant matrix. It retains many of the compounds naturally present in the plant alongside the standardised active — the whole botanical profile, concentrated to a defined specification. An isolate or near-isolate (90%+) is the result of further processing — chromatographic separation, recrystallisation, or solvent fractionation — that removes the surrounding matrix and concentrates a single compound to very high purity. The distinction matters for formulation: a standardised extract at 5% withanolides contains a broad Withania somnifera compound profile; a berberine HCl isolate at 95% is functionally a single compound with botanical origin. Both have legitimate formulation applications depending on your product brief.
How do I read the HPLC assay result on the CoA?
+
The CoA for a standardised extract will state the assay result as a percentage — for example, "withanolides: 5.2% (minimum specification: 5.0% by HPLC)". The result confirms the measured content from the specific lot you are receiving, not a reference standard applied across batches. For isolate-tier products, the CoA purity statement typically reads as "purity: 97.4% by HPLC" with the analytical method specified. The minimum specification on the product listing represents the guaranteed lower bound — individual lots may test higher. If you require a specific assay result for your regulatory file, request the CoA before order placement to confirm the current lot's result meets your formulation requirement.
Are these compounds suitable for use in food or beverages?
+
Regulatory status varies significantly by compound and target market. Some standardised extracts in this collection may be eligible in qualifying food supplement and functional food formulations in their target markets — confirm the applicable regulatory framework (EU Novel Food, FDA DSHEA, TGA) for your specific compound and application before formulating. Isolate-tier compounds (95%+ single compound) are typically used in supplement capsules, tablets, and sachets rather than food matrices, where their high potency and potentially narrow solubility profiles require careful formulation engineering. Contact us with your specific compound, intended application, and target market for guidance on available documentation.
What is the minimum order quantity and are samples available?
+
Standard minimum order is 250g for samples and 1 kg for bulk for most products in this collection. Some isolate-tier compounds with complex processing have higher minimums — confirm at enquiry stage. Samples are available with CoA and SDS before bulk commitment. For research applications requiring small quantities of high-purity isolates, contact us to discuss available formats.
How long does shipping from India take?
+
Standard international air freight from India takes 5–8 business days to the US, UK, EU, Canada, and Australia. Express air freight is available with a 72-hour despatch window for in-stock items. For time-sensitive orders, contact us before placing your order to confirm current stock availability and lead time for the specific lot.
