Core lineWithania somnifera · root
Ashwagandha extract
Root-only extract standardised to 5% withanolides by HPLC. The certificate states the plant part and the method, because that is what separates a good lot from a cheap one.

Botanical ingredients from India
Ingredients your customers will read on the label, from our own production facilities and direct sourcing in India. Seven core extracts held to specification, and the full range India produces, every line released against a batch certificate your QA team can read before anyone talks price.
Extracts, oils, oleoresins, powders, mushrooms and botanicals
Held to a fixed specification and shown in depth

Seven core lines
Each one has its own page with the grades we supply, how they are specified, how they are packed and the questions buyers actually ask.
Core lineWithania somnifera · root
Root-only extract standardised to 5% withanolides by HPLC. The certificate states the plant part and the method, because that is what separates a good lot from a cheap one.
Core lineCurcuma longa · rhizome
The isolated active behind most joint, liver and inflammation-positioned formulations in the UK. 95% total curcuminoids by HPLC; water-dispersible 10% for beverage.
Core lineCurcuma longa · full spectrum
The whole rhizome concentrated ten-fold rather than a single molecule isolated out of it, with the actual curcuminoid content reported per batch.
Core lineMoringa oleifera · leaf
Shade-dried leaf only, milled to 80 mesh and screened; steam-sterilised grade for tight micro limits and a 10:1 extract for capsules.
Core lineZingiber officinale · rhizome
Standardised to 5% gingerols by HPLC. Oil-soluble grade for capsules and blends, water-dispersible grade for shots, beverages and gummies.
Core lineTrigonella foenum-graecum · seed
Seed extract standardised to 50% saponins, the market-standard grade behind testosterone-support, lactation and blood-sugar formulations.
Core lineEmblica officinalis · fruit
Indian gooseberry standardised on tannins, which are stable and measurable, rather than on vitamin C, which degrades in processing and is routinely overstated.
Anything else
Berberine, milk thistle, bacopa, boswellia, functional mushrooms, essential oils, oleoresins, natural colours and more, sourced against your specification with the same certificate pack.
The full range
Extracts, oils, oleoresins, powders, colours and dried botanicals, sourced from the region that grows each one best, plus functional mushrooms and the non-Indian botanicals a complete formulation needs. If a line is not here, send the specification and we will tell you plainly whether we can hold it. Grades, forms and assay methods for every line are in the portfolio.
Standardised herbal extracts
Standardised to a marker compound by the method named on the certificate. HPLC where the marker allows it; gravimetric or UV where that is the industry convention, stated as such.
12 linesStandardised herbal extracts
The immune, liver and gut actives that UK brands reformulate around every winter. Berberine and milk thistle are the two fastest-growing lines in this group.
14 linesStandardised herbal extracts
The high-volume actives behind most UK finished products. Most are held at several strengths; the grade a buyer needs usually follows from the dose per capsule.
15 linesStandardised herbal extracts
Inside-out beauty and antioxidant actives, plus the cosmetic-grade materials skincare formulators ask for.
11 linesStandardised herbal extracts
Lower-volume botanicals that ayurvedic and traditional-format brands still need, held to identity and purity with a ratio or marker where one exists.
6 linesFunctional mushroom extracts
Sold as extracts, not mushroom powder: fruiting body declared, beta-glucan content measured by the Megazyme method, species confirmed by DNA or HPTLC, and heavy metals, microbiology and pesticide residue on every certificate. Hot-water and dual (water and ethanol) extractions available.
6 linesThrough our partner manufacturers
These are grown elsewhere and reach us through the same GMP-certified manufacturing partners, with the same batch certificate and testing pack. Origin is stated on every document. Listed so a buyer can consolidate a full formulation with one supplier.
12 linesEssential oils
Supplied with GC-MS profile per lot, with the chemotype named. Bulk in aluminium or epoxy-lined drums; food-grade and cosmetic-grade documentation on request.
24 linesFixed and carrier oils
Cold-pressed, filtered and packed under nitrogen where the oil oxidises quickly. Refined grades and butters to specification.
12 linesOleoresins and spice extracts
Solvent-extracted or CO2 oleoresins with the active or colour value reported per lot. Water-dispersible and oil-soluble forms, and spray-dried encapsulated powders, to specification.
14 linesNatural powders, colours and functional ingredients
Spray-dried, freeze-dried or milled to specification. Colour ingredients carry colour value per lot; gums carry viscosity and mesh.
10 linesDried botanicals and tea cuts
Tea-cut (TBC) and whole-leaf grades, with moisture, microbiology and pesticide screening. Steam-sterilised where a brand's micro limits demand it.
6 linesThe portfolio
Thirteen pages covering the seven core extracts in depth, the full range of herbal extracts, essential oils, oleoresins, powders and functional mushrooms, and an A–Z index so you can find what you are looking for in seconds.



With every batch

How an order runs
Six steps, most of them ours. You send a specification; we come back with a certificate and a delivered price, and the goods arrive tested, cleared and documented.
The active, the percentage, the form and the volume. Or the certificate you buy against today, supplier name redacted.
A recent batch certificate for the line and a delivered duty paid price in sterling.
Specification, packing and delivery address agreed in writing.
Assay, heavy metals, microbiology, pesticide residue and residual solvent. Material that will not pass does not ship.
Customs entry, duty and GB import controls handled by Aarleez Ltd as importer of record.
Delivered with the full document pack. Batch codes trace back to the source lot.
A great deal of extract on the market is standardised by a method that reads anything that behaves like the marker. We put HPLC on the certificate wherever the marker allows it, and we say which method we used when it does not.
FAQ
Aarleez Ltd supplies standardised botanical extracts business-to-business across the United Kingdom, importing direct from source in India. The range covers ashwagandha, curcumin, turmeric, moringa, ginger, fenugreek and amla, in 25 kg drums, with a lot-tied Certificate of Analysis and the lot certificate drawn from the batch being quoted.
It means the extract is manufactured to hit a stated percentage of a named marker compound — 5% withanolides in ashwagandha, 95% curcuminoids in curcumin — measured by a stated analytical method. A ratio extract such as turmeric 10:1 is different: it concentrates the whole plant part ten-fold without isolating anything, and its marker content varies with the crop.
Because gravimetric and UV methods read broad classes of compounds while HPLC separates and quantifies specific ones. The same physical material can honestly be described as 5% by HPLC and as a much higher figure by a gravimetric method. If your specification names a percentage but not a method, the cheapest way for a supplier to satisfy it is the method that reads highest — so always write the method into the specification.
Twenty-five kilograms per specification, which is one standard fibre drum. Mixed consignments across two or more actives are accepted on a first order so you can qualify several ingredients at once. Five-kilogram foil pouches are available for pilot batches and stability work.
Our standard offer is conventional. Certified organic material can be sourced to order against a valid, unbroken certificate from farm to delivery, which carries a longer lead time and a separate price. We quote it honestly rather than implying certification we cannot evidence.
Usually. Send the incumbent Certificate of Analysis — supplier name redacted if you prefer — and we will tell you plainly whether we can match it, better it, or not hold it consistently. We would rather lose the enquiry than win it on a specification we cannot repeat on the second order.
The marker assay by the stated method, plus heavy metals, microbiology, pesticide residue, and residual solvent where solvent extraction was used. Concentrated extracts concentrate soil contaminants along with the actives, so heavy metals matter more on a 10:1 extract than on the raw herb.
One to two weeks from order confirmation to a UK address on running specifications, quoted delivered duty paid in sterling. Bespoke specifications requiring a fresh production run take longer and we give the real date at quotation.
