Quality Control

Our Birch Leaves Extract is produced under strict quality management protocols. Each batch is tested to ensure identity, purity, and consistency, with specifications often targeting key marker compounds like flavonoids (e.g., hyperoside, quercetin) and triterpenes (e.g., betulin). We provide comprehensive Certificates of Analysis (COA) detailing assay results, heavy metals, microbial limits, and residual solvents, supporting compliance with cGMP, ISO, and relevant pharmacopoeial guidelines.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at controlled room temperature (15-25°C).
