Overview
ISO 19661:2026 - Traditional Chinese medicine - Anemarrhena asphodeloides rhizome sets international quality and safety requirements for the rhizome of Anemarrhena asphodeloides (commonly "Zhimu"), a key herbal ingredient in Traditional Chinese Medicine (TCM). This ISO standard applies to both whole medicinal materials and decoction pieces derived from Anemarrhena asphodeloides and is designed to ensure consistency, safety, and traceability in global trade. It is widely utilized in the export, processing, and regulatory oversight of natural medicines, supporting the harmonization of standards across regions.
Key Topics
-
Quality and Safety Specifications:
The standard defines strict requirements for the physical, chemical, and safety attributes of Anemarrhena asphodeloides rhizome. These include:
- Cleanliness and removal of foreign matter and fibrous roots
- Absence of visible contaminants, insects, or mold
- Morphological and microscopic identification
- Moisture, total ash, and acid-insoluble ash content limits
- Testing for heavy metals (arsenic, mercury, lead, cadmium)
- Limits on pesticide residues
- Marker compound quantification (such as mangiferin)
-
Standardized Sampling and Testing:
Methods for sampling, macroscopic/microscopic examination, thin-layer chromatography (TLC), and quantitative testing are standardized to ensure reliable results.
-
Packaging, Transportation, and Labelling:
Requirements ensure the rhizome is packaged for protection against light, moisture, contamination, and damage during transit. Labelling must include origin, mass, production/expiry dates, storage methods, and quality details, following global TCM product standards.
-
Test Reporting:
Specific elements for complete and clear test reporting are outlined, supporting full traceability and regulatory compliance.
