Flame atomic absorption spectrometry determination of trace elements in medicinal six cough phlegm

目的:采用火焰原子吸收光谱法测定罗汉果、桔梗、川贝母、半夏、百部及前胡6种中草药中的微量元素含量。方法:用硝酸和高氯酸(3+1)对样品进行消解,火焰原子吸收光谱法测定罗汉果、桔梗、川贝母、半夏、百部及前胡中Cu、Zn、Mg、Mn微量元素的含量。结果:Mg的含量最高,其后是Zn、Mn、Cu。结论:实验发现罗汉果、桔梗、川贝母、半夏、百部及前胡等6种止咳化痰类中草药含有多种对人体有益的微量元素,具有一定的药用价值及科学研究价值。

Objective： using flame atomic absorption spectrometry determination of fructus momordicae, platycodon grandiflorum, unibract fritillary bulb, pinellia, radix stemonae and hu before six kinds of trace elements in Chinese herbal medicine. Methods： using nitric acid and perchloric acid digestion, the samples （3 ＋ 1 ） to flame atomic absorption spectrometry determination of fructus momordicae, platycodon grandiflorum, unibract fritillary bulb, pinellia, radix stemonae and Cu in former hu, zinc, Mg, Mn content of trace elements. Results： Mg is the highest content of commercial, followed by zinc, Mn, Cu. Conclusion： this lab found in fruetus momordicae, platycodon grandiflorum, unibract fritillary bulb, pinellia, radix stemonae and hu before six medicinal cough phlegm contains a variety of trace elements beneficial to human body, which has some medicinal value and scientific research value.
