Overview
ISO 25003:2026 specifies the quality and safety requirements for root and rhizome of Gentiana scabra, Gentiana manshurica, and Gentiana triflora. These medicinal plants are essential herbal ingredients in Traditional Chinese Medicine (TCM), collectively known as “Longdan” (龙胆), and are widely used in Chinese materia medica. The standard applies to the whole medicinal material and its decoction pieces intended for international trade, providing harmonized benchmarks for quality assurance, safety, and regulatory compliance.
With global demand for Gentiana root and rhizome increasing steadily, ISO 25003:2026 serves as a critical reference for manufacturers, traders, regulators, and healthcare professionals seeking to ensure the safety, efficacy, and traceability of these herbal medicines worldwide.
Key Topics
- Quality Requirements: The standard defines essential parameters such as moisture content, total ash, acid-insoluble ash, and the presence of water-soluble extractives.
- Morphological and Microscopic Identification: Detailed criteria for the physical and microstructural properties of the roots and rhizomes are outlined, supporting accurate identification and prevention of adulteration.
- Chemical Identification: Use of thin-layer chromatography (TLC) and high-performance liquid chromatography (HPLC-UV) for verifying marker compounds, such as gentiopicroside.
- Safety Parameters: Maximum limits for heavy metals (including arsenic, lead, mercury, and cadmium), pesticide residues, and sulfur dioxide are specified.
- Sampling and Testing Methods: Standardized procedures for sample collection, analysis, and result reporting to ensure repeatability and global alignment.
- Packaging, Storage, and Labelling: Prescriptions for appropriate packaging materials, protective transportation, optimal storage conditions, and international labelling requirements.
