Quality Control

Our Polyphyllin Vi is produced and tested under a strict quality management system. Each batch undergoes comprehensive analysis to ensure identity, purity, and consistency, meeting the stringent requirements for pharmaceutical reference materials. Certificates of Analysis (COA) detailing purity, assay results, and chromatographic profiles are provided and available upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at a controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed in a low-humidity environment to prevent degradation.
