Engineered for absolute accuracy, reproducible chromatography, and fast-track global regulatory dossier validation.
Transforming the empirical variability of natural botanicals into quantifiable, reproducible molecular science across international borders.
Phytochemical analytical development requires rigorous proof of specificity, linearity, precision, recovery limits, and ruggedness under varied chromatographic conditions. MedGence (Yineng Pharma) deploys strict validation matrices guaranteeing testing frameworks adhere smoothly to FDA, EMA, and NMPA filing prerequisites.
Purity verification goes far beyond active compound quantification. Utilizing Triple-Quadrupole LC-MS/MS and ICP-MS systems, our analytical pipelines identify, isolate, and quantify heavy metals (Pb, As, Cd, Hg), organophosphorus pesticide residues, solvent residues, and mycotoxins below ppb (parts per billion) thresholds.
Single-marker quantification fails to address the totality of plant-derived active complexes. By establishing high-density multi-wavelength HPLC profiles and High-Performance Thin-Layer Chromatography (HPTLC) fingerprints, we establish definitive botanical provenance, eliminating adulteration.
Combining high-capacity automated continuous counter-current extraction units with intelligent Process Analytical Technology (PAT).
Our pilot and commercial facilities utilize in-line Near-Infrared (NIR) spectroscopic probes and automated refractometers. Continuous parameter adjustment prevents thermal degradation of thermolabile bioactives, ensuring target molecules maintain native functional integrity throughout the batch run.
With strategic GAP (Good Agricultural Practices) sourcing hubs across authentic Chinese cultivation origins (Daodi regions), we mitigate seasonal potency fluctuation. Real-time geographical marker quantification allows precise blending, delivering commercial extract supplies with less than ±1.5% lot-to-lot compound variance.
By linking laboratory discovery, pilot scale-up (50L–2000L), and massive commercial extraction within our integrated ecosystem, international clients achieve 35% to 50% accelerated time-to-market along with lower capital expenditures compared to Western contract testing laboratories.
Empirical leadership backed by real scientific breakthroughs, hospital approvals, and enterprise delivery.

Targeted, verified solutions addressing the most pressing bottlenecks encountered by multinational formulation leaders.
Demand undeniable label-claim verifiability without spike adulteration. We provide dual-instrument validated assays (HPLC + Mass Spec) that ensure standard active levels (e.g. Ginsenosides, Curcuminoids, Icariin) withstand secondary testing audits from retailers and third-party inspectors.
Navigating tight safety margins and regional cosmetic ingredient exclusions (INCI compliance, EU 1223/2009). Our team establishes purity dossiers confirming absence of prohibited free anthraquinones, residual allergens, and micro-contaminants while proving skin barrier penetration via in vitro assays.
Requiring complete chemistry, manufacturing, and controls (CMC) documentation according to FDA Botanical Drug Guidance. We conduct full stability stress testing (photostability, thermal, humidity) under ICH Q1A(R2) conditions, supporting Phase I to Phase IV clinical investigations.
Where analytical precision meets predictive algorithms to shorten development cycles from years to months.
Applying machine learning across historical TCM formulation databases to predict binding affinities of botanical ligands against specific disease targets, cutting exploratory screening time by 60%.
Transitioning classical thermal extraction to automated supercritical CO₂ with co-solvent modifiers, maximizing recovery of lipophilic fractions with zero toxic solvent residue.
Deploying Q-TOF-MS systems for non-targeted metabolomic profiling. This enables comprehensive holistic multi-compound tracing across biological serums during animal and clinical evaluations.
Integrating tamper-proof digital records from field planting, wild harvesting, extraction PAT logs, and final certificate of analysis (COA) testing to deliver infallible supply chain provenance.
Directly addressing tariff, quality documentation, and regulatory hurdles with localized bilingual project teams.
Every method developed and batch manufactured by MedGence is harmonized against United States Pharmacopeia (USP), European Pharmacopoeia (Ph. Eur.), British Pharmacopoeia (BP), and Chinese Pharmacopoeia (ChP) monographs, ensuring zero import rejection risks.
Operating exclusively under mutual non-disclosure and strict CDMO entrusted research structures. Our technical facilities physically segregate proprietary customer projects. No formula parameters, manufacturing workflows, or assay methodologies are ever shared or repurposed.
From our Changsha R&D center, dedicated bilingual project managers provide transparent weekly video reporting, analytical chromatogram raw-data transfers, and real-time project milestone tracking aligned with North American, European, and Asia-Pacific time zones.
Over a decade of R&D services entrusted by China's foremost healthcare institutions and multinational healthcare brands.
