分析桔梗药材中有效成分含量、重金属和农药残留,为桔梗的质量控制和标准制定提供依据。方法:采用原子吸收光谱法测定铅、砷、镉,ICPMS法测定汞的含量,气相色谱法测定有机氯农药残留量。结果:桔梗总皂苷10.18%,铅(0.05mg/kg,汞(0.01mg/kg,砷(0.14mg/kg,镉(0.09mg/kg,BHC(8ug/kg,DDT(4ug/kg,PCNB未检出。结论:桔梗药材中含一定量重金属。
Analysis of the content of active ingredients, heavy metals and pesticide residues in Campanulaceae, provide the basis for the quality control and standard formulation of Campanulaceae. Methods: The content of mercury was determined by atomic absorption spectrometry, and the content of organochlorine pesticide was determined by gas chromatography. Results: The content of total saponins in Campanulaceae was 10.18%, the concentrations of lead (0.05mg / kg, mercury (0.01mg / kg, arsenic (0.14mg / kg, cadmium Detected.Conclusion: Campanulaceae herbs contain a certain amount of heavy metals.
