Curcuma longa · 95% Curcuminoids · Actual BatchThe most widely used standardised anti-inflammatory botanical
Turmeric Extract is produced from the dried rhizome of Curcuma longa — the bright golden root that has been central to Ayurvedic and culinary use for centuries. While culinary turmeric powder contains only about 2–5% curcuminoids, a standardised extract concentrates that active fraction; the most traded grade worldwide is 95% total curcuminoids by HPLC.
The active markers are the curcuminoids — a group of three closely related polyphenols: curcumin (the most abundant), demethoxycurcumin (DMC) and bisdemethoxycurcumin (BDMC). A genuine plant-derived extract shows all three in their natural ratio on the HPLC trace; that fingerprint is what separates a true botanical extract from synthetic curcumin. The rhizome also contains aromatic turmerones in its volatile oil, which are concentrated in oleoresins rather than the 95% powder.
SV Botanica sources turmeric from India's established growing belts — Erode in Tamil Nadu, Sangli in Maharashtra, Andhra Pradesh, and the high-curcumin Lakadong variety of Meghalaya — and standardises via a validated solvent-extraction and purification process, with every batch assayed by HPLC. The result is a clean, bright orange-yellow powder for joint-health, antioxidant, sports-nutrition and functional-food formulations.
We supply supplement brands, contract formulators and food & beverage companies across Europe, the USA, the Middle East and Asia. Buyers new to the category can start with our turmeric & curcumin extract buyer's guide.
Key phytochemicals driving turmeric's activity profile
The headline active fraction, standardised to 95% by HPLC. A complex of three polyphenols that defines a genuine standardised extract.
The most abundant curcuminoid (typically ~70–80% of the complex) and the reference compound for HPLC assay and most published research.
The second curcuminoid; its presence and ratio are part of the natural fingerprint used to confirm a plant-derived extract.
The third curcuminoid. All three together produce the authentic HPLC pattern that a single synthetic-curcumin peak cannot replicate.
Aromatic ar-turmerone and related sesquiterpenes from the rhizome's essential oil — concentrated in oleoresins, minimal in the 95% powder.
Native rhizome carbohydrates that dominate raw turmeric powder and are largely removed during standardisation to the 95% grade.
Evidence from clinical trials, systematic reviews, and mechanistic research
Curcumin is the most-studied dietary modulator of inflammatory signalling, acting on pathways such as NF-κB. A widely cited review summarises its mechanisms and human evidence in inflammatory conditions.
Ref: Hewlings SJ & Kalman DS, 2017; FoodsA systematic review and meta-analysis of randomised trials found standardised curcuminoids reduced knee osteoarthritis pain and improved function, supporting turmeric's leading role in joint formulations.
Ref: Daily JW et al., 2016; J Med FoodCurcuminoids scavenge free radicals and support the body's own antioxidant enzymes, a mechanism reviewed extensively in the biochemical literature on curcumin's protective activity.
Ref: Menon VP & Sudheer AR, 2007; Adv Exp Med BiolA controlled human study reported that co-administering piperine (from black pepper) markedly increased the bioavailability of curcumin — the basis for the common curcumin + black pepper pairing.
Ref: Shoba G et al., 1998; Planta MedicaA meta-analysis of randomised trials reported that curcumin/curcuminoid supplementation was associated with favourable changes in circulating lipids in certain populations, consistent with metabolic-support positioning.
Ref: Qin S et al., 2017; Nutrition JournalEarly randomised, placebo-controlled trials have explored curcumin for mood support, adding to an active research area alongside its better-established anti-inflammatory and joint applications.
Ref: Lopresti AL et al., 2014; J Affect DisordResponsible-marketing note: finished-product claims must be substantiated and compliant with each destination market's regulations. EFSA set an Acceptable Daily Intake for curcumin (E100) of 3 mg/kg body weight per day in its 2010 re-evaluation, so formulators should calculate and declare the finished-product curcuminoid dose and keep it within applicable guidance.

Curcuminoids are quantified by HPLC — the reference method that resolves curcumin, DMC and BDMC and exposes synthetic substitution. Because turmeric is a historic lead-adulteration risk, every batch is tested for lead by ICP-MS and screened for illegal dyes. A current Certificate of Analysis, MSDS, and allergen/Non-GMO declarations are issued with every batch. Specifications for granular, water-dispersible, organic and ratio grades available on request.
From rhizome to finished extract — traceable, tested, certified
Raw Material Sourcing: Turmeric rhizome is sourced under Good Agricultural and Collection Practices (GACP) from India's principal growing belts — Erode (Tamil Nadu), Sangli (Maharashtra), Andhra Pradesh, and the high-curcumin Lakadong variety of Meghalaya. Incoming material is authenticated by botanical identity and by HPLC curcuminoid fingerprint against reference standards before processing.
Manufacturing: Extraction and purification are carried out in GMP-certified facilities (WHO-GMP and ISO audited) using validated parameters to reach 95% total curcuminoids. Each batch runs a full QC battery — HPLC curcuminoid assay, an adulterant and synthetic-curcumin screen, lead and heavy-metals by ICP-MS, pesticide-residue GC-MS/LC-MS, residual solvents, and a full microbiological panel — before release. Lead testing on every batch is non-negotiable given turmeric's documented adulteration history.
Documentation: Every shipment comes with Certificate of Analysis (CoA), MSDS, Allergen Declaration, BSE/TSE-free statement, Non-GMO affidavit, Country of Origin Certificate, and Phytosanitary Certificate. Organic, Halal and Kosher certificates are available for the appropriate grades. Buyers can review our full process in the turmeric sourcing & quality guide and our adulteration & synthetic-curcumin guide.
Full compliance for global B2B supply
Key information for global product registration and labelling
Curcumin is approved as the food colour E100, and turmeric has a long history of food use. EFSA set an Acceptable Daily Intake of 3 mg/kg body weight/day for curcumin in its 2010 re-evaluation. Highly concentrated curcumin extracts intended for supplements should be checked against current novel-food positions, and labelling must comply with Regulation (EU) 1169/2011. Confirm curcuminoid dose and heavy-metal limits before launch.
Turmeric and curcumin are classified as dietary ingredients under DSHEA (21 CFR Part 111), and turmeric/curcumin have GRAS status for defined food uses. No pre-market approval is required for dietary supplements; importer facility registration with the FDA is required. Structure-function claims are permissible with 30-day FDA notification and substantiation; joint and anti-inflammatory claims must be credibly supported.
FSSAI-compliant for food-supplement use under the FSS (Health Supplements, Nutraceuticals) Regulations 2022. Accepted in Japan, the Middle East (Halal grades), Southeast Asia, Australia (TGA) and Canada (NNHPD). Because turmeric is a known lead-adulteration risk, heavy-metal (especially lead) limits should be confirmed per destination market and supported by ICP-MS data on each CoA. See our curcumin regulatory compliance guide.
