[Objective] The aim was to study the distribution of main mineral elements in different parts of Cistanche tubulesa. [Method] With C. tubulesa as the materials, they were vertically (base, top, middle and lower) and laterally treated (6 thin layers and core layer were divided from outer to inner and 6 thin layers consisted 3 treatments). Trace element contents in samples were determined after green removing, weighting and grinding. [Result]In lateral and vertical distribution of mineral element in C. tubulesa, the contents of Na and K were the highest and the following were those of P and Ca. Except Na, other element contents were gradually decreased from outer to inner. K content was decreased from top to base. The contents of P, Ca, Fe and Mn in two ends were higher and those in middle were lower. Al content in base was the highest (0.82%), and the contents of Mg and Zn in top were the highest, while their contents in other parts had little difference. [Conclusion]The distribution law of mineral elements in different parts of Cistanche tubulesa was different.%[目的]研究主要矿质元素在肉苁蓉不同部位的分布.[方法]以管花肉苁蓉为材料,对其进行纵向(基部、顶端、中部和下部)和横向处理(从外向内分为6个薄层和芯,6个薄层合成3个处理),样品杀青、称重、粉碎后测定微量元素含量.[结果]矿质元素的横向分布和纵向分布中,Na、K含量最高,其次为P和Ca;除Na外,其他几种元素含量从外层到内层逐渐降低;K含量从顶端到基部逐渐降低,P、Ca、Fe和Mn含量两端高中间低.Al含量基部最高(0.82%),Mg、Zn含量顶端最高,其他部位差别不大.[结论]矿质元素在肉苁蓉不同部位的分布规律不同.
