目的:研究荆半夏不同分化品系对微量元素的吸收与富集规律。方法:应用波长色散X射线荧光光谱分析法对荆半夏4个品系的叶和块茎粉末中的微量元素进行检测。结果:荆半夏4个品系的叶和块茎中共检测到18种微量元素,总平均值由大到小分别为K,Ca,Cl,S,P,Mg,Na,Si,Al,Fe,Zn,Mn,Sr,Cu,Cr,Ni,Se,Ti。叶中未检测到Se,块茎中未检测到Ti。结论:荆半夏的4个品系对不同微量元素的吸收和富集存在差异性,是否对其参与配伍的功效表现差异性,值得进一步研究。
Objective: To study the absorption and enrichment of trace elements in different differentiated lines of Jingbianxia. Methods: The wavelength-dispersive X-ray fluorescence spectrometry was used to detect trace elements in leaf and tuber powder of Jingbaixia 4 lines. Results: 18 trace elements were detected in leaves and tubers of Jingbianxia 4 cultivars. The total average values were K, Ca, Cl, S, P, Mg, Na, Si, Al, Fe, Zn , Mn, Sr, Cu, Cr, Ni, Se, Ti. Se was not detected in leaves, and Ti was not detected in tubers. CONCLUSION: There are differences in the absorption and enrichment of trace elements among the four strains of Jingbianxia, and their differences in the efficacy of their participation and compatibility deserve further study.
