摘要
采用微波消解-火焰原子吸收光谱法测定秦岭山区2种金粟兰属药用植物银线草和多穗金粟兰中铁、锌、铜、锰、钙、镁、钠、钾的含量。结果显示:银线草和多穗金粟兰中含有丰富的宏量和微量元素,银线草中所测元素含量依次为K>Ca>Na>Mg>Fe>Zn>Mn>Cu,多穗金粟兰为K>Ca>Mg>Na>Fe>Mn>Zn>Cu;所测得的8种元素中,银线草中的含量均高于多穗金粟兰,加标回收率在95.7%—108.2%之间,相对标准偏差(RSD)均小于5%。该方法简便、快捷、灵敏、准确,为探讨微量元素与银线草和多穗金粟兰的药效关系及进一步开发利用提供了理论依据。
The contents of macro and trace elements （iron, zinc, copper, manganese, calcium, potassium, sodium and magnesium） in Chloranthus japonicus Sieb. and Chloranthus multistachys Pei were determined by flame atomic absorption spectrophotometry （FAAS） with microwave digestion. The results showed that the order of concentrations of macro and trace elements in Chloranthus japonicus Sieb. and Chloranthus rnultistachys Pei were K〉Ca〉Na〉Mg〉Fe〉Zn〉Mn〉Cu and K〉 Ca 〉 Mg 〉 Na 〉 Fe 〉 Mn 〉 Zn 〉 Cu, respectively. The contents of these elements in Chloranthus japonicus Sieb. were higer than that in Chloranthus multistachys Pei. The standard addition recoveries of samples were in the range of 95.7%--108. 2% ,and the relative standard deviation was lower than 5%. The method was simple and rapid with good precision and accuracy, which would provide theoretical bases for discussing the relationship between the contents of these elements and the medical effects,and further utilization of Chloranthus japonicus Sieb. and Chloranthus multistachys Pei.
