Our premier product line features state-of-the-art bioactive phytochemicals, bile-derived acids, and premium natural components rigorously optimized for diagnostics, therapeutics, and health supplements.
Chengdu ChenLv Herb Co.,Ltd. (referred to as "Chenlv Herb") was established in 2012 as a pioneering high-tech enterprise specializing in the research, development, production, and global supply of high-purity botanical extracts, active biochemical substances, and natural pharmaceutical ingredients. Committed to providing premium-grade, highly active, and chemically characterized raw materials, the company serves international markets across pharmaceuticals, health supplements, food, diagnostics, and cosmetic industries.
Our focus extends to strict regulatory alignment, assuring diagnostic kit manufacturers and biochemical supply entities that our derivatives conform to crucial markers of purity, traceability, and batch reliability.
By leveraging advanced isolation techniques such as column chromatography, molecular distillation, and high-performance crystallization, Chenlv Herb bridge the gap between crude natural source materials and ultra-pure chemical entities like conjugated bilirubin precursors and bile salts essential for modern IVD systems.
Over a decade of dedication to botanical extraction science, natural derivative refinement, and rigorous quality certifications.
In modern clinical chemistry, Conjugated Bilirubin (often referred to in laboratory diagnostics as Direct Bilirubin or Conj Bilirubin) is an indispensable clinical biomarker. Accurate measurement of conjugated bilirubin levels in serum or plasma is essential for diagnosing liver dysfunctions, neonatal jaundice, biliary tract obstructions, and metabolic hepatic conditions such as Dubin-Johnson and Rotor syndromes. Because diagnostic accuracy directly impacts clinical outcomes, the regulatory framework governing diagnostic reagents and calibrators has become increasingly stringent.
Conjugated bilirubin consists of bilirubin covalently bound to glucuronic acid molecules, rendering it water-soluble. Unlike unconjugated bilirubin, which is highly lipophilic and bound to albumin, conjugated bilirubin reacts directly with diazo reagents in aqueous solutions. From an analytical perspective, conjugated bilirubin is notoriously unstable. It is highly susceptible to photo-oxidation, thermal degradation, and spontaneous deconjugation.
For IVD companies developing diagnostic assays, procuring stable, high-purity Conjugated Bilirubin calibrators and controls is paramount. Suppliers must deliver materials that possess high chemical stability, minimal batch-to-batch variation, and a defined purity profile validated by HPLC.
With the transition from the old In Vitro Diagnostic Directive (IVDD 98/79/EC) to the new European In Vitro Diagnostic Regulation (IVDR 2017/746), clinical diagnostic assays and their critical calibration raw materials are subject to intensive oversight. Under IVDR, calibrators and control materials are evaluated as vital medical devices.
CE certification for Conjugated Bilirubin products is not merely a label; it represents complete conformity to performance specifications, analytical traceability, stability validation profiles under diverse temperatures, and a comprehensive risk management file. B2B purchasers must collaborate exclusively with companies that maintain certified quality management systems (such as ISO 13485 and ISO 9001).
Historically, conjugated bilirubin was obtained via complex extraction processes from natural mammalian bile. However, these crude extracts often carried high risks of viral contamination, protein impurities, and unpredictably variable ratios of mono-conjugated and di-conjugated fractions.
At Chenlv Herb, we deliver botanical chemistry and diagnostic-grade raw materials engineered to support global compliance frameworks and demanding supply timelines.

Fast validation cycles and rapid batch turnaround to seamlessly meet your aggressive diagnostic product launch timelines.
A highly trained, dedicated regulatory team supporting your validation dossiers at every step of the verification process.
Over a decade of chemical engineering and extract standardization expertise ensuring unmatched purity and analytical performance.
Global B2B procurement networks for medical devices and critical reagents are shifting from transaction-oriented buying to highly integrated supplier alliances. Procurement managers at major IVD developers (such as Roche, Abbott, Siemens, and Beckman Coulter) face immense pressure to secure reliable, compliant suppliers of highly specialized diagnostic compounds.
When sourcing Conjugated Bilirubin, sourcing directors face three major risks: supply chain disruption, batch-to-batch diagnostic drift, and compliance gaps. A failure in raw material stability can trigger product recalls, leading to multi-million dollar penalties and reputational damage.
Consequently, key procurement requirements include:
To address these procurement requirements, companies like Chenlv Herb provide end-to-end integration options. We act as a strategic contract manufacturing organization (CMO) that coordinates raw material sourcing, purification, chemical stabilization, and custom formulation packaging.
By consolidating natural chemical extraction (e.g., producing high-purity Ox Bile Powder, Sodium Deoxycholate, and Taurochenodeoxycholic acid) alongside clinical grade diagnostic reagents, we control the purification process from beginning to end. This vertical integration reduces pricing volatility and secures batch homogeneity for diagnostic kit manufacturers worldwide.
Our biological raw materials and botanical compounds serve four core global market segments, supporting health, therapy, beauty, and animal nutrition.
Driven by the concept of "homology of medicine and food" and modern wellness trends, our natural extracts offer ideal pathways for natural, green, and highly biomimetic nutraceutical products.
From botanical formulas documented in ethnopharmacology to modern drug discovery projects, our pure active molecules play pivotal roles in therapeutics, drug validation, and assay testing.
Meeting the modern clean beauty demand, our bio-actives provide mildness, high biocompatibility, and targeted cellular benefits including anti-oxidation, brightening, and natural barrier support.
Enhancing animal health and boosting overall physiological resilience, our standardized extracts serve as clean, highly bioavailable feed additives for modern livestock and aquaculture.
Navigating the regulatory systems of different clinical regions requires local expertise. While CE-IVDR compliance is crucial for the European Economic Area, B2B companies targeting the North American market require FDA registrations, and Asian markets necessitate PMDA or NMPA compliance.
At Chenlv Herb, we provide localization compliance support by offering multi-lingual documentation, customized regulatory support kits, and technical support teams stationed in major global logistics hubs. By supplying complete validation data regarding biocompatibility, heavy metal safety, and chemical characterization, we help clients register their finished clinical systems smoothly.
The future of diagnostic bile pigments and conjugated bilirubin rests on two key pillars: absolute molecular control and biological sustainability. Over the next decade, the IVD industry expects:
