摘要
目的:分析玉米须中芹菜素及微量元素的含量,为玉米须的质量评价提供理论依据。方法:采用高效液相色谱法测定芹菜素的含量,采用原子吸收光谱法测定玉米须中铜、铁、镁、钾、锌元素的含量。结果:不同产地玉米须中芹菜素及微量元素含量差异较大。芹菜素的含量为0.000 6%~0.034 1%,Cu、Fe、Mg、K、Zn的含量范围分别为3.32~20.12μg·g^(-1)、0.14~0.66μg·g^(-1)、2.23~3.39μg·g^(-1)、0.82~6.73μg·g^(-1)、0.01~0.45μg·g^(-1)。结论:本研究所建立的芹菜素及微量元素测定方法稳定,可为玉米须饮片的质量控制提供依据。
Objective ： To determine the contents of apigenin and trace elements in Maize Whiskers and to provide a theoretical basis for the evaluation of the quality of it. Methods ： The content of apigenin was determined with HPLC method, and the contents of cop- per,iron, magnesium, potassium, zinc in Maize Whiskers were determined with atomic absorption spectrometry method. Results ： The contents of apigenin and trace elements in Maize Whiskers of different origins are quite different, in which the content of apige- nin is 0.000 6 -0.034 1% ,while that of Cu,Fe,Mg,K,Zn were 3.32 -20. 12,0. 14 -0.66,2.23 -3.39,0.82 -6.73 and 0.01 -0.45 μg . g-1 respectively. Conclusion ：The content determination method of apigenin and trace elements in Maize Whisk- ers established in this study is of stable quality and can be provided to a new theoretical basis for the control of Maize Whiskers slices.
