Operating advanced supercritical CO2 fluid extraction alongside low-temperature ethanol reflux systems. This preserves delicate naphthoquinone pigments (shikonin derivatives) without heat-induced thermal degradation.
Every commercial drum is accompanied by a batch-specific COA, HPLC spectrum analysis, heavy metal screening (ICP-MS), pesticide residue panel (USP/EP standards), and microbiology clearing.
We partner directly with botanical GAP (Good Agricultural Practice) farms in Xinjiang, Shaanxi, and Henan. Complete origin traceability guarantees zero adulteration and uniform raw material species verification.
Gromwell Extract, derived predominantly from the dried roots of Lithospermum erythrorhizon Siebold & Zucc., Arnebia euchroma (Royle) Johnst., or Arnebia guttata Bunge, represents one of the most chemically intriguing and commercially significant botanical raw materials originating from China. Known historically for its vibrant crimson shade and therapeutic properties, modern pharmacological research isolates its red naphthoquinone pigments—collectively designated as Shikonin derivatives—as the primary drivers of its anti-inflammatory, antimicrobial, wound-healing, and skin-barrier restorative actions.
High-grade Gromwell Root extracts are quantitatively evaluated via High-Performance Liquid Chromatography (HPLC) for total shikonins, specifically measuring Shikonin, Acetylshikonin, Isobutyrylshikonin, β,β-Dimethylacrylshikonin, and β-Hydroxyisovalerylshikonin. Premium batches target a combined pigment yield of 10% to 30% in CO2 extracts and up to 98% in isolated pure monomer fractions.
The manufacturing architecture for Gromwell Extract dictates both its pharmacological efficacy and regulatory compliance in foreign markets. Conventional solvent extraction using warm ethanol or hexanes frequently risks thermal decomposition of the unstable ester bonds in acetylshikonin. Furthermore, organic solvent residues pose ongoing compliance challenges under European Union (EU) Regulation (EC) No 396/2005.
To eliminate solvent toxicity and prevent thermal degradation, our plant utilizes Supercritical Fluid Extraction with Carbon Dioxide (SFE-CO2). Operating under parameters of 25–35 MPa pressure and temperatures controlled precisely between 35°C and 45°C, supercritical CO2 acts as a non-polar solvent with gas-like diffusivity and liquid-like solvent power. This process yields a dark red, lipophilic oleoresin with zero residual organic solvents, ideal for clean-label cosmeceuticals and pharmaceutical topical ointments.
| Extraction Technology | Active Content (Total Shikonins) | Solvent Residue Status | Thermal Degradation Risk | Primary Target Application |
|---|---|---|---|---|
| Supercritical CO2 Extract | 10.0% – 30.0% Oleoresin | 0 PPM (Solvent-Free) | Negligible (< 40°C process) | Clean-label skincare, softgels, barrier creams |
| Ethanol Reflux Extract | 1.0% – 5.0% Powder / Liquid | < 50 PPM (Standardized) | Moderate (requires vacuum recovery) | General dietary supplements, herbal soaps |
| Chromatographic Pure Monomer | 95.0% – 99.0% Shikonin Crystal | Controlled per USP/EP | Requires dark vacuum cold storage | API research, medical dressings, reference standards |
In modern cellular health and cosmetic formulations, Gromwell Root extract is frequently combined with Sophora Japonica extracts. Sophora Japonica serves as China’s richest biological source for bioflavonoids, notably Rutin and Quercetin (Anhydrous and Dihydrate). When formulated together:
As global buyers adjust to tightening global safety standards, procurement directors are altering their vendor evaluation criteria. Key market trends shaping future B2B sourcing include:
A. Microencapsulation & Liposomal Delivery Systems
Native shikonin and quercetin compounds exhibit limited aqueous solubility. B2B demand is rapidly shifting toward pre-formulated Liposomal Quercetin 50% and water-dispersible Gromwell powders. Microencapsulation using phospholipid complexes increases bioavailability by up to 4.5 times while masking intense herbal colors where necessary.
B. Pyrrolizidine Alkaloid (PA) Depletion Requirements
Certain Boraginaceae species naturally synthesize trace Pyrrolizidine Alkaloids (PAs), which are subject to stringent regulations in Europe (e.g., Commission Regulation (EU) 2020/2040 limit of < 1.0 ppm). RAAG Biotech employs resin chromatography post-extraction to selectively deplete PAs while concentrating active shikonins, guaranteeing audit-ready compliance for EU and US buyers.
C. Standardized Granulations for Direct Compression
Downstream manufacturers are rejecting fine, light-density powders that cause dusting and hopper bridging during encapsulation. Direct compression (DC) granular formats—such as our 98% Granular Quercetin—drastically improve powder flowability, speed up tableting rates, and reduce production downtime.

We utilize Reverse-Phase High-Performance Liquid Chromatography (RP-HPLC) with UV detection at 516 nm for accurate quantization of total shikonin derivatives. UV-Vis spectrophotometry can also be provided upon request, though HPLC is recommended to prevent over-estimation caused by non-active plant pigments.
Yes. Every batch destined for international export undergoes LC-MS/MS testing for 28 regulated Pyrrolizidine Alkaloids. We guarantee total PA levels below 1.0 mg/kg (1.0 ppm), complying strictly with Regulation (EU) 2020/2040 for herbal food supplements and cosmeceuticals.
Our standard MOQ for standardized plant powders and standardized extracts is 1 kg. For high-purity monomers (>98% Shikonin or Quercetin Anhydrous), the MOQ starts at 100g. We provide free 10g to 50g evaluation samples complete with lot COAs for laboratory testing prior to commercial orders.
Absolutely. We offer tailored carrier systems including organic maltodextrin, rice starch, or gum arabic. Mesh sizes can be micronized from standard 80 mesh up to 300 mesh for ultrafine suspension needs. Water-soluble emulsion forms of Gromwell CO2 extract are also available for beverage and cosmetic lotion systems.
Each production batch is tagged with a unique Lot Identification Number (LIN). This code maps directly back to the harvest plot, GAP cultivation logs, drying parameters, extraction operational records, and laboratory release analysis. Retained samples of all exported lots are stored in our climate-controlled archive for 36 months.
In-stock standardized items ship within 3 to 5 business days following payment confirmation. Custom extraction runs, liposomal microencapsulations, or specialized particle sizing typically require 10 to 15 working days. Full customs dossiers (MSDS, COA, Flow Chart, Allergen Statement, COO) are included with all air and ocean shipments.
