摘要: 采用四-(对氨基苯基)-卟啉(T4-APP)柱前衍生,以固相萃取富集,利用高效液相色谱法测定四种广东常用煲汤药材(五指毛桃、鸡骨草、海底椰和土茯苓)及其汤底中六种重金属元素:镍、铜、锡、铅、镉、汞的含量。结果表明四种药材均含有一定量的重金属元素,其中以铜含量最高,浓度范围为12.96~37.28μg/g,而汞含量最低为0.07~0.73μg/g;经过长时间煲煮后,汤底中的重金属元素残留比例有所差异,其中镉(Cd)的残留量最高,达到63.97%~76.32%,而铜(Cu)的残留量最低,仅为26.56%~36.67%。土茯苓具有最高含量的铜元素为37.28%,但其锡、铅和汞元素的含量最低,分别为0.69、0.37和0.07μg/g,并且在汤底中的残留比例最高,分别为75.36%、91.89%和85.71%;其它三种药材及其汤底中残留重金属含量相近,没有明显差异。

Abstract: A new method for the determination of nickel, copper, tin, lead, cadmium and mercury elements in Hearty Chinese Soup herb (Ficus simplicissima, Abrus cantoniensis, Polygonatumodoratum druce and Smilax glabra) by solid phase extraction and high performance liquid chromatography was studied. The nickel, copper, tin, lead, cadmium and mercury ions were pre- column derived by tetra-(amidogenphenyl)-porphine (T4-APP). The results show that copper element has the highest content with 12.96~37.28μg/g and mercury has the lowest content with 0.07~0.73μg/g in those herb; and the decocted herb has a few of residues metal elements, cadmium had the highest rudimental proportion with 63.97%~76.32% and copper has the lowest with 26.56%~36.67%. Smilax glabra has the lowest content of tin, lead and mercury, separately 0.69, 0.37, and 0.07 μg/g.
