Quality Control

Every batch of Yiyeliangwanoside Ii is produced and tested under a strict quality management system to ensure identity, purity, and consistency. Our standard grade meets high-purity specifications suitable for research and development applications. Comprehensive analytical testing, including HPLC, is performed to verify compliance. A detailed Certificate of Analysis (COA) is provided with each shipment to guarantee traceability and support your regulatory requirements.

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 sealed in a dry environment to prevent degradation. For long-term storage, consider desiccants or inert atmosphere conditions.
