目的:对重庆道地药材金银花的重金属含量进行分析评价,为制定金银花药材重金属含量质量标准提供参考依据.方法:对重庆主产区不同年份、不同品种金银花药材样品的铅、镉、铜含量(石墨炉原子吸收分光光度法)及汞、砷含量(原子荧光法)进行分析.结果:铅的含量为0.158~1.564 mg/kg;镉的含量为0.009~0.069 mg/kg;汞的含量为0.010~0.078 mg/kg;铜的含量为0.162~0.364 mg/kg;砷的含量为0.457~2.172 mg/kg.不同产地、不同品种间铅和砷的差异性较大.结论:金银花药材基本上达到了《药用植物及制剂进出口绿色行业标准》相应的重金属限量标准,可进行规模化种植.
OBJECTIVE: To analyze and evaluate the heavy metal content of honeysuckle in Chongqing, and to provide a reference for formulating the quality standard of heavy metal in honeysuckle.METHODS: The content of lead, cadmium and copper in different years and different varieties of honeysuckle in Chongqing Graphite furnace atomic absorption spectrometry) and mercury, arsenic content (atomic fluorescence method) were analyzed.Results: The content of lead was 0.158 ~ 1.564 mg / kg, the content of cadmium was 0.009 ~ 0.069 mg / kg, the content of mercury was 0.010 ~ 0.078 mg / kg; the content of copper was 0.162 ~ 0.364 mg / kg; the content of arsenic was 0.457 ~ 2.172 mg / kg.Differences between lead and arsenic in different cultivars were greater.Conclusion: The “Import and export of medicinal plants and preparations of green industry standards,” the corresponding standard of heavy metals, for large-scale cultivation.
