Empowering global life science enterprises with validated botanical characterization, reproducible analytical chemistry, pharmacodynamics screening, and cGMP turnkey contract manufacturing.
From raw herbal screening and validated chromatographic standardization to animal toxicology and clinical development.
The international natural medicine and nutraceutical sectors are navigating a paradigm shift. Historically, herbal extracts and botanical compounds suffered from batch-to-batch inconsistency, ambiguous chemical fingerprints, and fragmented clinical documentation. Global regulatory bodies—including the US FDA (21 CFR Part 111/312), the European Medicines Agency (EMA HMPC), and Health Canada—now mandate strict evidence-based characterization, chromatographic validation, and toxicological substantiation.
As leading China Scientific Methods Manufacturers & Suppliers, MedGence (Yineng Pharma) bridges ancient empirical Traditional Chinese Medicine (TCM) insights with precision analytical biopharmaceutics. Operating from Changsha, Hunan—the historic cradle of Chinese herbal raw material processing—our integrated CRO and CDMO infrastructure removes the knowledge-gap barriers that typically plague tech transfers from laboratory assays to high-throughput commercial batches.
Rigorous quantitative evidence built through long-standing technical execution with top-tier pharmaceutical conglomerates.
Full value-chain engineering from primary phytochemical exploration to industrial dosage formulation.
High-throughput identification of plant secondary metabolites including polyphenols, saponins, terpenes, and bioactive polysaccharides. Quantitative affinity profiling isolates highest therapeutic densities.
View screening protocols →Botanical efficacy depends fundamentally on terroir (soil mineral profile, sunlight indices) and harvest season. We deliver comparative chromatographic mapping to select optimal geographical sourcing.
View origin studies →Eliminating analytical ambiguity with validated HPLC, HPTLC, and GC-MS fingerprints. Precise identification limits, active compound quantification, and degradation kinetics protocols tailored for global compendia.
Explore analytical methods →Engineering scalable downstream chemical extraction protocols: supercritical CO2 separation, counter-current chromatography, and macroporous resin adsorption for high recovery yield and reduced environmental impact.
Review process workflows →Resolving bioavailability bottlenecks, oxidation susceptibilities, and taste-masking in complex multi-herb formulations. Ensuring full stability retention over 24-month accelerated and real-time stress testing.
View stability documentation →Full-spectrum GLP preclinical safety portfolios: LD50 acute oral toxicity assays, 90-day sub-chronic repeated dose tests, Ames genotoxicity screening, and chromosomal aberration assays for regulatory dossiers.
Preclinical toxicity files →Cellular mechanism of action discovery across primary human cell lines and enzyme models. Validating receptor binding, antioxidant pathways, anti-inflammatory cascades, and metabolic enzyme regulation.
In vitro assays portfolio →Targeted disease animal models (rodent/murine) for metabolic syndromes, neurological targets, immuno-oncology adjuvants, and organ protection studies under institutional animal ethics controls.
Animal model data →Double-blind, placebo-controlled clinical study design and execution for dietary claims substantiation and medicinal registration (IND/NDA dossiers) in compliance with ICH GCP standards.
Clinical study models →Deconstructing synergistic poly-herbal interactions using network pharmacology. Translating empirical decoctions into standardized, micro-encapsulated solid doses suitable for Western commercial channels.
TCM modernization scope →Dedicated pilot plants and high-capacity extraction vessels supplying concentrated extracts, high-purity crystalline powders, aromatic distillates, and viscous oleoresins with complete trace audit trails.
Active ingredient catalog →Turnkey cGMP formulation production spanning oral liquids, vegetarian hard capsules, enteric softgels, multilayer tablets, and high-dissolution instant herbal granules under confidential packaging.
Finished dosage specs →Why Tier-1 global life science procurers rely on China's localized botanical extraction clusters and strict international compliance.
China encompasses four climate zones hosting over 12,000 documented medicinal botanical species. Our central positioning in Hunan provides direct contract farming access to indigenous Daodi (genuine medicinal materials) origins across Yunnan, Sichuan, Guizhou, and Changbai Mountain, securing unbroken cold-chain tracking and zero adulteration risk from cultivation to extraction.
Bridging the infamous laboratory-to-industry "Valley of Death": China's complete manufacturing supply chain allows seamless transition from bench-scale gram syntheses to metric-ton automated extraction runs within a single regulatory governance framework. Our engineering team optimizes solvent recycling, energetic enthalpy efficiency, and automated continuous separation, driving production costs down 35–50% versus Western equivalents.
We operate in strict alignment with international pharmacopeias (USP, Ph. Eur., BP, ChP). We provide full Electronic Common Technical Document (eCTD) dossier support, ICH-guided stability reports, Non-GMO verification, heavy metal monitoring (ICP-MS testing down to parts-per-billion), and multi-residue pesticide screening covering over 400 agrochemical compounds.
Meeting the exacting empirical criteria demanded by international brand architects and product formulators.
Demanding water-soluble, clinically verified botanical extracts with documented human study endpoints for structure/function claims on retail shelves and Amazon distribution.
Requiring single-molecule purity or tight complex fingerprint ranges supported by complete GLP toxicology, Phase I PK/PD data, and validated analytical test release methods.
Clean-label, skin-permeable actives backed by in vitro keratinocyte and melanocyte pathway validation, zero skin sensitization, and low organoleptic color/odor impact.
Acid-stable, thermally resilient botanical complexes with rapid dissolution profiles and neutral taste vectors for RTD functional canned beverages and soluble sachet packs.
A transparent 6-stage engineering process guaranteeing technical deliverables at every programmatic milestone.
Phytochemical screening, geographical variance quantification, and botanical taxonomical authentication.
Development and validation of HPTLC, HPLC, and GC-MS reference methods with strict precision and specificity criteria.
Pilot extraction optimization, purification solvent recovery cycles, crystallization parameters, and spray drying settings.
Cellular assays, in vivo efficacy validation, acute oral LD50 determination, and GLP genotoxicity clearance.
Pilot cohort safety evaluations and Phase I–IV GCP trials generating reproducible statistical power for registration.
