Engineered in pharmaceutical-grade Class D cleanrooms. Every batch features fully verified HPLC/UV active assay documentation, standardized solvent retention thresholds, and full regulatory export dossiers.
Headquartered in Xi'an's High-Tech Industrial Development Zone, Shaanxi ESNO Biotech Co., Ltd. operates at the global epicenter of botanical isolation. Leveraging the rich natural flora of the Qinling Mountains combined with multi-stage thermodynamic separation technologies, we supply premier ingredients and private label solutions worldwide.
Our facility incorporates Class D (ISO 8) cleanrooms equipped with positive pressure differential cascade systems, high-efficiency particulate air (HEPA) filtration, and real-time environmental monitoring. This prevents cross-contamination and preserves heat-labile phyto-complexes.

Reviewing our core botanical concentration technologies. Our manufacturing line selects specific extraction thermodynamic profiles based on bioactive molecular polarity and thermal stability.

Procurement executives face escalating supply chain scrutiny, shifting regulatory barriers, and evolving consumer transparency demands. Strategic sourcing requires a forward-looking perspective on manufacturing agility and compliance.
Generic botanical powders are increasingly rejected due to species adulteration risks. Tier-one procurement protocols now mandate genomic DNA barcoding and multi-element stable isotope ratio mass spectrometry (SIRMS) to prove authentic species identity and geographic provenance before bulk blending.
Anti-Adulteration ProtocolGlobal brand owners are phasing out magnesium stearate, silicon dioxide, and synthetic talc. Plant extract procurement now relies on functionalized organic rice hulls, bamboo silica, and pullulan or low-moisture HPMC shells to achieve 100% clean-label ingredient decks without slowing tableting or filling machines.
Excipient-Free DeliveryProcurement standards have shifted beyond simple heavy metal screens. US and EU customs enforce zero-tolerance limits for Ethylene Oxide (EtO) and 2-Chloroethanol, alongside mandatory testing for over 500 individual pesticide residues under USP <561> and pyrrolizidine alkaloid (PA) screenings.
Zero Ethylene Oxide GuaranteeRaw botanical extracts often exhibit poor systemic bioavailability, erratic lipophilic absorption, and high susceptibility to gastric acid breakdown. We develop targeted delivery matrices that help brands unlock superior pharmacokinetic performance.
Phosphatidylcholine liposomal coating encapsulates water- and oil-soluble phyto-molecules, bypassing hepatic first-pass degradation for up to an 8-fold bio-absorption boost.
Liposome Dry PowdersAcid-resistant vegetable shells and aqueous shellac micro-coating prevent early release in the stomach, shielding delicate enzymes like Lumbrokinase and live probiotic cultures.
pH-Dependent ReleaseSolubility-engineered botanical compounds engineered via cyclodextrin supramolecular complexes convert crystalline, poorly-soluble powders into instantly dispersible hydrophilic forms.
Dispersibility OptimizationFormulated ratios matching peer-reviewed physiological pathways—such as 40:1 Myo/D-Chiro Inositol or synergistic Vitamin D3+K2-MK7—to enhance receptor affinity and cellular uptake.
Metabolic Bio-SynergyEstablished in 2006, Shaanxi ESNO Biotech Co., Ltd. has developed over 400 custom formulations for more than 3,500 partners across 100+ countries. We handle production, documentation, and regulatory validation under a unified quality assurance system.

Comprehensive regulatory and technical answers to help purchasing managers, QA auditors, and supplement brand owners qualify our facility and products.
We employ a multi-step botanical authentication protocol. Incoming shipments undergo botanical macroscopic/microscopic identity checks followed by High-Performance Thin-Layer Chromatography (HPTLC) fingerprinting against reference standards from the United States Pharmacopeia (USP) or European Pharmacopoeia (Ph. Eur.). For high-risk botanicals, we conduct genomic DNA barcoding to confirm species authenticity and exclude unlisted plant fillers or adulterants.
Every production batch includes an exhaustive Certificate of Analysis (COA) detailing: physical characterization (mesh particle size, tapped density), chemical active marker quantification by HPLC/UV, loss on drying, total ash, residual solvents (USP <467>), heavy metals (Lead, Arsenic, Cadmium, Mercury via ICP-MS), and microbiological limits (Total Plate Count, Yeast/Mold, E. coli, Salmonella via USP <2021/2022>). Supplementary third-party tests (Eurofins, SGS) are available upon request.
To support both scaling brands and high-volume distributors, our MOQ tiers are structured by dosage format. For proven, stock encapsulated formulas (such as our Vitamin D3, Lumbrokinase, or Apigenin lines), private label MOQs start as low as 100 to 500 bottles with custom label application. Fully custom, proprietary client formulations requiring bespoke tooling, unique excipient blending, or specialized organic certification typically require an initial run of 1,000 to 3,000 units.
Yes. We specialize in clean-label manufacturing. We provide plant-based hard capsules using vegetable cellulose (HPMC) or tapioca pullulan, completely free of carrageenan, animal gelatins, and synthetic colorants like titanium dioxide. For tablet and capsule blending, we eliminate magnesium stearate and synthetic talc, substituting clean functional ingredients like organic rice hull concentrate (Nu-RICE) and bamboo extract silica.
Stability testing is conducted in strict accordance with ICH Q1A(R2) guidelines. Formulations undergo both real-time testing (25°C ± 2°C / 60% RH ± 5% RH) and accelerated environmental testing (40°C ± 2°C / 75% RH ± 5% RH) inside qualified climate chambers. Active marker decay curves, moisture pickup, lipid peroxide values, and disintegration times are systematically tested over 24- to 36-month periods, ensuring products meet label claims through expiration.
Pilot sample formulation and physical prototype production typically take 7 to 10 business days for client evaluation. Upon formal sample approval and packaging die-line authorization, mass commercial production—including raw material assaying, blending, encapsulation, bottling, induction sealing, and lot coding—is completed within 3 to 4 weeks. We offer express air-freight and temperature-controlled sea-freight options to all major global ports.
