QUALITY CONTROL OF CHINESE VELVET ANTLER BY PROFILING OF PESTICIDE RESIDUES AND HEAVY METALS
Applied Ecology and Environmental Research
Quality control is the most critical issue for Chinese medicines (CMs) as its increasing acceptance all around the world. This study measure and analyse the pollution of nine kinds of velvet antlers, which is one of the classical Chinese medicines, in different species and parts of Cervus Nippon and Cervus Elaphus in China. Following the relevant Chinese national standards to evaluate the pollution, we employed the Quick Easy Cheap Effective Rugged and Safe multiresidue method (QuEChERS),
... d (QuEChERS), combinating with gas chromatography (GC), for the analysis of the organochlorine pesticides (OCPs) in velvet antler. The Inductively Coupled Plasma Mass Spectrometry (ICP-MS) method was used to detect lead, cadmium, copper and arsenic in nine kinds of velvet antlers. The content of mercury and the pollutants in the nine kinds of velvet antlers were all in line with the Chinese Pharmacopoeia. However, these results showed that velvet antler as the unique animal medicine also has a certain amount of pesticide residues, and the individual detection indicators in antler, such as heavy metal copper, are high, which suggests that, we still need to conduct reasonable testing and analysis of heavy metals and pesticide residues in velvet antler before giving it to patients to ensure the safety of clinical application.
