目的:比较分析补益中药中微量元素的含量。方法:对11种中药进行清洗后用烘箱60℃低温烘干,再用粉碎机进行粉碎,用分析天平精确称取1.0000g,使用马弗炉500℃高温下进行碳化灰化,待完全灰化后冷却至室温,加入HC:lHNO3为1∶1溶液溶解,微微加热后用50ml容量瓶进行定容,待用原子吸收分光光度计测量补益中药中铁(Fe)、铜(Cu)、锌(Zn)、锰(Mn)等微量元素的含量。结果:补益中药中铁(Fe)、铜(Cu)、锌(Zn)、锰(Mn)含量都很丰富。结论:铁(Fe)、铜(Cu)、锌(Zn)、锰(Mn)是补益中药中主要组成部分,有助于机体正常运行。
Objective: To comparatively analyze the contents of trace elements in traditional Chinese medicine. Methods: After cleaning 11 kinds of traditional Chinese medicines, they were dried in an oven at a low temperature of 60 ° C, pulverized with a pulverizer, accurately weighed 1.0000 g with an analytical balance, and carbonized ashed with a muffle furnace at a high temperature of 500 ° C until completely ashed After cooling to room temperature, was added HC: lHNO3 1: 1 solution was dissolved, slightly heated with a 50ml volumetric flask to be determined by atomic absorption spectrophotometer to measure the iron (Fe), copper (Cu), zinc ), Manganese (Mn) and other trace elements. Results: The contents of Fe, Cu, Zn and Mn in the replenishing herbs were rich. Conclusion: Iron (Fe), copper (Cu), zinc (Zn) and manganese (Mn) are the main components of traditional Chinese medicine, which helps the normal operation of the body.
