How to Source Standardised Herbal Extracts Without Regulatory Rejection: Assay Methods, EU MRLs, and Supply Integrity

A ratio extract (such as 10:1) merely indicates that ten kilograms of starting dry botanical material were extracted to produce one kilogram of final extract. It does not provide any verifiable quantitative guarantee regarding active pharmacological compounds. In contrast, a standardised herbal extract is chemically engineered and validated to deliver an exact, consistent percentage of identified active phytochemical biomarkers (e.g., Curcuminoids 95% via HPLC, Withanolides 5% via HPLC) in every single manufactured lot, regardless of seasonal variations in agricultural harvests.

UV-Vis spectrophotometry calculates total light absorbance across a generic wavelength spectrum. As a result, it frequently measures non-active botanical tannins, pigment precursors, and related degraded molecules alongside the target active, resulting in artificially elevated assay values. High-Performance Liquid Chromatography (HPLC) physical-chemically separates each chemical constituent through a specialized stationary phase column, measuring distinct individual retention peaks against certified USP/Ph. Eur. reference standards. For instance, Milk Thistle tested by UV may read 80% Silymarin, but when tested by HPLC it may only yield 50-60%. Specifying the assay method is essential for commercial alignment.

SV Botanica completely prohibits ethylene oxide gas fumigation and irradiation across its entire processing and storage network. We utilize validated dry steam pasteurization systems to achieve microbiological safety without generating chemical degradation artifacts. For every consignment intended for European Union and UK ports of entry, samples are submitted to accredited third-party international laboratories to verify non-detectable levels of both Ethylene Oxide and 2-Chloroethanol, operating well below the strict EU Limit of Quantification (LOQ) of 0.05 mg/kg pursuant to Regulation (EU) 2019/1793.

All batches undergo Inductively Coupled Plasma Mass Spectrometry (ICP-MS) following standard USP <232>/<233> and Ph. Eur. 2.4.27 protocols. Typical maximum release thresholds are: Lead (Pb) < 3.0 ppm (or < 1.0 ppm on custom grades), Cadmium (Cd) < 1.0 ppm, Arsenic (As) < 1.0 ppm, and Mercury (Hg) < 0.1 ppm. Custom analytical specifications can be engineered to satisfy strict regional standards such as California Proposition 65 limits or Regulation (EU) 2023/915.

Yes. While certain hygroscopic extracts require carrier aids during spray-drying (such as maltodextrin, gum acacia, or silicon dioxide), SV Botanica has engineered dedicated carrier-free manufacturing processes for multiple prominent botanical items, including Ashwagandha, Turmeric, and Boswellia. Where a carrier is technologically required to prevent caking, its exact composition and percentage are explicitly disclosed on the Certificate of Analysis and Technical Data Sheet.

Our standard Minimum Order Quantity (MOQ) is 25 kg per individual item, packaged inside food-grade double polyethylene bags enclosed within durable fibre drums. Prior to contract execution, we dispatch 50g–100g pre-shipment validation samples accompanied by full lot-specific Certificates of Analysis. Commercial lead times generally range between 2 to 3 weeks from order confirmation to Indian port departure. Payment instruments include standard Letter of Credit (L/C) and Telegraphic Transfer (T/T) structures.

To support US importers fulfilling their Foreign Supplier Verification Program (FSVP) under FSMA, SV Botanica provides an exhaustive compliance pack: facility ISO and GMP registrations, process hazard analyses (HACCP), process flowcharts, allergen control declarations, residual solvent validation (USP <467>), environmental microbiological monitoring summaries, and official APEDA/FSSAI regulatory licenses.
