目的对同年次生包头市种植地采集和药店采集蒙古黄芪中重金属铅的含量进行比较研究。方法按照《中国药典》2010年版规定,采用石墨炉原子吸收法测定蒙古黄芪中铅的含量,用SPSS统计软件包对检测数据进行统计分析,对种植地采集和药店采集两组数据进行独立样本t检验。结果蒙古黄芪中铅的检出率为100%。包头市种植地采集蒙古黄芪中铅含量为(0.546 8±0.327 2)μg/g,包头市药店采集蒙古黄芪中铅含量为(1.280 8±0.460 8)μg/g。结论包头市药店采集蒙古黄芪中铅含量高于种植地采集蒙古黄芪,且含量水平均未超出《中国药典》2010年版黄芪项下的有关规定(Pb≤5μg/g)。说明黄芪在加工、贮存和生产炮制等过程中,可能受到不同程度有毒、有害物质的污染,但仍在允许范围内。
OBJECTIVE To compare the contents of heavy metals Pb in Mongolian Astragalus collected from the secondary Baotou planting sites and the pharmacies in the same year. Methods The content of lead in Radix Astragali was determined by Graphite Furnace Atomic Absorption Spectrometry according to the 2010 edition of “Chinese Pharmacopoeia”. SPSS statistical package was used for statistical analysis of the test data. Two sets of data were collected from planting site and pharmacy for independent samples t test. Results The detection rate of lead in Mongolia Astragalus was 100%. The lead content in Mongolian Astragalus collected from Baotou City was (0.546 8 ± 0.327 2) μg / g. The lead content in Mongolian Astragalus collected from Baotou Pharmacy was (1.280 8 ± 0.460 8) μg / g. Conclusion The content of lead in Mongolian Astragalus collected from Baotou Pharmacy is higher than that of Mongolian Astragalus collected from the planting sites, and the content of Pb in Mongolian Astragalus is not beyond the requirements of the Chinese Pharmacopoeia 2010 Edition (Pb≤5μg / g). Description Astragalus processing, storage and processing of the process of processing, may be varying degrees of toxic and harmful substances in the pollution, but still within the allowable range.
