Instant dissolution without sediment or cloudy flocs. Instant black tea powder and sodium copper chlorophyllin survive UHT/HTST pasteurization while preserving bioactive polyphenols and vivid hues.
Our Stinging Nettle Root and standardized mushroom extracts feature uniform tapped density and controlled moisture content (≤ 5.0%), eliminating die sticking, powder bridging, and formulation loss.
Bio-active extracts and plant colorants stripped of harsh solvent residues. Tested to strict microbiological parameters (USP <61/62>) for direct inclusion in dermatological gels, serums, and masks.
Modern consumers demand clean nutrition without synthetic additives. Here is how current sourcing demands reflect evolving global quality benchmarks.
The global push away from synthetic FD&C and artificial lake colorants has created unprecedented wholesale demand for botanical alternatives like water-soluble Sodium Copper Chlorophyllin, Blue Spirulina Phycocyanin, and Micronized Purple Ube.
Under regulation BS EN 15662 and EC 396/2005, green tea and botanical imports face multi-residue pesticide sweeps. Brands require verified certificates showing non-detectable levels of anthraquinone, perchlorate, and chlorate.
Commodity "extract ratios" (e.g., 10:1) are rapidly being rejected by enterprise brands in favor of calibrated marker molecules (e.g., HPLC-verified β-sitosterol in Urtica dioica or Mogroside V percentages in monk fruit).
How Xi'an Vexli Bio-Tech validates chemical integrity before consignment release:
| Analytical Parameter | Laboratory Testing Method | Standard Acceptance Criteria | Technical Operational Impact |
|---|---|---|---|
| Phytochemical Assay | HPLC (High-Performance Liquid Chromatography) | Target active compound ±2% against standard reference | Guarantees active efficacy across commercial formulation runs. |
| Heavy Metals Sweep | ICP-MS (Inductively Coupled Plasma Mass Spectrometry) | Pb ≤ 1.0 ppm, As ≤ 1.0 ppm, Cd ≤ 0.5 ppm, Hg ≤ 0.1 ppm | Complies with California Prop 65, EU EC 1881/2006, and US Pharmacopeia standards. |
| Residual Solvents | GC-MS (Gas Chromatography with Headspace) | Methanol, Acetone, Hexane < USP <467> limits | Prevents solvent entrapment and ensures compatibility with sensitive ingestible products. |
| Pesticide Multi-Residue | LC-MS/MS & GC-MS/MS (BS EN 15662) | Over 500 individual compounds: < 0.01 mg/kg or Non-Detected | Prevents custom holds, border rejections, and brand reputational damage. |
| Microbiological Limits | Plate Count, Selective Culturing (USP <61/62>) | TPC < 1,000 CFU/g; Yeast/Mold < 100 CFU/g; Negative Salmonella/E. Coli | Eliminates risk of contamination in ambient shelf-stable retail drinks and foods. |
Headquartered in Xi'an, Shaanxi Province—the epicenter of Chinese botanical research—Xi'an Vexli Bio-Tech combines traditional botanical resources with state-of-the-art purification and quality infrastructure.
We avoid volatile third-party spot markets. Botanicals are harvested directly at contract plantations and processed in verified partner facilities, ensuring complete lot-to-field traceability and price stability.
Confidence backed by transparency: Our facility operations, cleanroom extraction workshops, warehouse management, and QC operations have passed comprehensive on-site inspections conducted by SGS.
Holding active invention and utility model patents (such as ZL 2014 1 0464649.9 and Utility Patent No. 14520048), our processing preserves heat-sensitive actives with higher yields and improved purity.
We supply bulk ingredients to international contract manufacturing giants and consumer brands in over 30 countries, operating with an established annual export turnover exceeding US$29.5 Million.
We empower both startup innovators and enterprise procurement teams by providing standard botanical extracts with accessible trial minimums from 1 kg, up to 20-foot full container deliveries.
Equipped with complete IATA DGR and IMDG marine non-dangerous goods classifications, our shipping team manages rapid air dispatch and sea container clearance to European and American ports.
Every bulk shipment is supported by accredited certifications and complete traceability:
Direct clarity on logistics, documentation, custom specifications, and quality verification.
For most of our standardized herbal extracts, instant tea powders, and organic matchas, our standard Minimum Order Quantity begins at just 1 kg. This allows formulators to conduct industrial pilot trials and bench tests. Select specialty items carry higher base MOQs (e.g., Marine Collagen Peptides at 25 kg, D-Allulose at 50 kg).
Every commercial delivery includes a batch-specific Certificate of Analysis (COA) confirming assay, moisture, ash, heavy metals, and microbiological values. On request, we provide Technical Data Sheets (TDS), Safety Data Sheets (MSDS), European Pesticide Multi-Residue sweeps (BS EN 15662), and Organic Transaction Certificates (TC).
Yes. We operate commercial milling, micronization, and vibrating sieve systems capable of producing mesh profiles from 60 mesh up to 800+ mesh (such as our ceremonial matcha and butterfly pea powders). We can also adjust tap density to match specific high-speed rotary capsule filling equipment.
We offer flexible shipping terms including FOB China ports, CFR, CIF, FCA, EXW, and complete DDP (Delivered Duty Paid with customs duties and inland transit arranged to your warehouse). We accept settlements via T/T, L/C, PayPal, and Credit Cards in USD, EUR, GBP, CAD, AUD, and CNY.
Every commercial batch is produced using strict Standard Operating Procedures (SOPs). Raw materials are tested for identity, purity, and active markers prior to extraction. We maintain retained reference samples for 24 months from every shipped lot to ensure complete quality traceability.
Yes. We routinely provide 50g–100g verification samples to qualified brand procurement teams and certified contract packagers. This enables your internal analytical lab and R&D team to independently test solubility, assay markers, and sensory attributes before issuing purchase contracts.
