Safety and Quality Control Testing

Our Quality Assurance teams routinely execute the following QC tests to ensure safety and high quality products: Macroscopic (visual) inspection: authenticate the herb species and parts used. Microscopic examination: authenticate the herb species by histological examination and comparison with certified reference standard specimen. TLC (thin layer chromatography): verify the identity of herb species by comparing its unique analytical identification with certified reference standard herb. HPLC/PDA (high performance liquid chromatography coupled photo diode array detector): measure potency and batch consistency by quantifying the content of active ingredients. HPLC/ELSD (high performance liquid chromatography coupled evaporative light scattering detector): determine the quality of rehmannia by analyzing its S to M saccharide ratio. ICP/MS (gas chromatography coupled mass spectrometry): measure heavy metal elements to ensure product safety. GC/MS (gas chromatography coupled mass spectrometry): screen for pesticide residue to ensure product safety. HPLC/FD (coupled fluorescent detector): check the content of aflatoxin to ensure product safety. LC/MS (coupled mass spectrometry): screen for the existence of aristolochic acid to ensure product safety. Microbiological testing: analyze yeast & mold and pathogenic microorganism to ensure product safety.
