目的:建立6个不同药店穿心莲中4种重金属元素的检测方法,并对其含量水平和健康风险进行初步评价。方法:采用微波消解—原子吸收光谱法定量分析广州市6个不同药店穿心莲中铅、镉、铜、铬等4种重金属元素的含量。结果:健民(利众店)和采芝林(神农轩分店)的穿心莲样品Pb超标,而Cd元素除采芝林(南方分店)的穿心莲合格之外,其它均超标。从重金属总量来看,健民(利众店)的穿心莲超标较严重。结论:从健康风险指数来看,健民(利众店)和采芝林(神农轩分店)穿心莲的含铅量、采芝林(神农轩分店)和康美药店售穿心莲的含镉量及健民(利众店)的穿心莲含铬量,都可能会对人体健康产生一定风险,应该予以重视。
OBJECTIVE: To establish a method for the determination of 4 heavy metal elements in Andrographis paniculata in 6 different pharmacies, and to evaluate its content and health risks. Methods: Microwave digestion - atomic absorption spectrometry was used to quantitatively analyze the contents of four heavy metal elements such as lead, cadmium, copper and chromium in Andrographis paniculata in six different pharmacies in Guangzhou. Results: The Pb of Andrographis in Jianmin (Leezhong Branch) and Cai Zhi Lin (Shennongxuan Branch) exceeded the standard, while the contents of Cd exceeded the standards of Andrographis paniculata in Cai Zhi Lin (Southern Branch). From the total amount of heavy metals point of view, Kin (Lee Public Shop) Andrographis more serious than the standard. Conclusion: From the health risk index, the lead content of Andrographis paniculata (Jianin Lin Branch) and the Kangmei pharmacy Andrographis paniculata in Jianmin (Lee Chung Shop) and Cai Zhi Lin (Shen Nong Xuan Branch) Min (Lee Public Shop) of Andrographis Chromium content, may have some risks to human health, it should be taken seriously.
