摘要
为对"浙八味"药材质量控制和安全用药提供可靠的依据,采用灰化法处理样品,火焰原子吸收分光光度法测定了其铅、镉、铜含量。结果表明,8种药材中的铅含量为0.828 1~1.747 3 mg.kg-1,镉含量为0.116 9~0.295 0mg.kg-1,铜含量为2.519 5~8.286 4 mg.kg-1。8种药材均检出一定量的有害重金属,但含量较低,未超出国家限量标准,符合《药用植物及制剂进出口绿色行业标准》的有关规定。
To supply the reference for the quality control and the safety of the content of lead(Pb),cadmium(Cd)and copper(Cu)in "Zhejiang 8 Famous Kinds" herbal medicines.Samples were digested with dry ash method and the Pb,Cd and Cu were determined by flame atomic absorption spectrophotometry.The results showed that the content of lead,cadmium and copper was 0.828 1～1.747 3 mg·kg-1,0.116 9～0.295 0 mg·kg-1 and 2.519 5～8.286 4 mg·kg-1respectively.It concluded heavy metals that detected in all samples were under the li...
