摘要
目的:测定10批黔产羊耳菊药材中的重金属汞、砷、铅、镉及铜的含量,评价黔产羊耳菊药材的质量及安全性。方法:10批不同产地(黔产)羊耳菊药材,采用石墨炉原子吸收光谱法测定药材中铅、镉、铜的含量,原子荧光光度法测定药材中砷、汞的含量,以《药用植物及制剂进出口绿色行业标准》对10批药材中重金属含量进行评价。结果:被测定的10批黔产羊耳菊药材中铅、铜、砷的含量均未超出限定标准,有1批罗甸药材中汞的含量超出限定标准;除1批惠水药材及1批罗甸药材外,其余药材中镉的含量均超出限定标准。结论:贵州省内不同产地的羊耳菊药材中重金属的含量存在较大差异,镉含量超标较为严重。
Objective： To determine the amount of heavy metals in 10 different batches of Inula cap- pa produced in Guizhou Province and evaluate quality and clinical safety. Methods： The contents of heavy metals of Pb, Cd and Cu were determined by using graphite furnace atomic absorption spectrom- etry, and As and Hg by atomic fluorescence spectrometry. According to Green Trade Standards of Im- porting Exporting Medicinal plants Preparations, the experimental data of l0 batches of lnula cappa were evaluated. Result： The contents of Pb, Cu and As in herbs did not exceed the limited standard. Hg content exceeded the limited standard in one batch produced in Luodian area. The Cd content in all of batches exceeded the limited standard except for one batch from Huishui and one batch from Luodi- an. Conclusion： The results shows there is a significant difference of the heavy metals contents in In- ula cappa produced among different producing areas in Guizhou Province. And the situation of Cd con- tent exceeding the permitted standard is serious.
