Traditional Chinese medicine (TCM) analytical reference standards

TCM analytical standards are reference materials characterized through mass balance methodology, which quantifies the active components in raw materials by deducting interfering substances such as moisture, residual solvents, and inorganic impurities. These standards undergo rigorous homogeneity verification and long-term stability monitoring. With defined properties and quantified values, they are essential for equipment calibration, analytical method validation, product quality assessment, and authentication, ensuring consistency and compliance in TCM production.

The categories of herbal analytical standards are extensive, covering raw herbs and decoction pieces, plant-based oils/extracts, single-ingredient formulations, and compound preparations.

Hengyuan Fine’s PCL brand offers over 3,000 types of herbal analytical standards and reference substances across the entire industrial chain, including materials like Ginseng and Astragalus, plant extracts (e.g., Tanshinone, Menthol), and more.

Each product is accompanied by detailed labels and certificates of analysis (COA), specifying name, CAS number, batch ID, molecular formula, molecular weight, purity, intended use, storage conditions, and other critical parameters.

PCL standards strictly comply with the Chinese Pharmacopoeia and ISO 17034:2016 guidelines. With ready-to-ship inventory, purity ≥98%, and comprehensive coverage, they support content determination, pharmaceutical research, quality control, and customized compliance solutions for innovation-driven projects.
