目的:测定中药蓝萼香茶菜中微量元素含量,完善其有效物质数据。方法:将样品经过预处理、高压釜消解后,以45Se、72Ge、115In、209Bi为内标物质,采用电感耦合等离子体质谱仪分析方法进行测定。结果:蓝萼香茶菜全草中含有48种微量元素,其中Mn、Zn、Rb、Sr、Ba的含量较高。结论:蓝萼香茶菜中含有种类丰富的微量元素,为充分利用蓝萼香茶菜提供了科学依据。
Objective: To determine the content of trace elements in the traditional Chinese medicine, Calyx Tea, and improve its effective substance data. Methods: After the sample was pretreated and autoclaved, 45Se, 72Ge, 115In and 209Bi were used as internal standard materials and determined by inductively coupled plasma mass spectrometry. Results: There were 48 kinds of microelements in the whole plant of Chai Xiang tea, among which, Mn, Zn, Rb, Sr and Ba contents were higher. Conclusion: The blue calyx fragrant tea dish contains a variety of trace elements, which provide a scientific basis for making full use of blue calyx tea.
