ICP - AES technology was used to determine the mineral elements content of Cistanche deserticola Ma (C. deserticola). The results showed that: (1) At succulent stem stages, the content of K was the highest in 5 macroelements, it can reach to 9.45 mg x g(-1), and the proportion for K : Na : P : Ca : Mg was 12 : 3.4 : 1.6 : 1.4 : 1. Among 5 microelements, the content of Fe was the highest and can reach to 97.31 microg x g(-1), and the proportion for Fe : Cu : Mn: Zn : Cu : B was 25 : 3.7 : 3.5 : 1.2 : 1. (2) At reproductive growth stages, the contents of Ca, Mg, Fe, Zn, Cu, Mn and B at unearthed stage were significantly higher than that at the underearth stage, especially for the content of Fe and Mn, they can respectively reach to 697. 55 and 38.75 microg x g(-1) at capsule formative stage. The contents of Fe and Mn at capsule formative stage were almost 7.2 and 8.3 times than that at succulent stem stage. (3) At reproductive growth stages, the aerial part will exclude Na and accumulate P, K, Ca, Mg, Fe, Mn, Zn, Cu and B. This result of the study will be a scientific basis for evaluating the quality of C. deserticola.
采用电感耦合等离子体发射光谱（ICP - AES）技术测定了肉苁蓉的矿质元素含量。结果表明：（1）在肉质茎阶段，5种大量元素中钾含量最高，可达9.45 mg·g⁻¹，K:Na:P:Ca:Mg的比例为12:3.4:1.6:1.4:1。5种微量元素中，铁含量最高，可达97.31 μg·g⁻¹，Fe:Cu:Mn:Zn:B的比例为25:3.7:3.5:1.2:1。（2）在生殖生长阶段，出土期的钙、镁、铁、锌、铜、锰和硼含量显著高于地下期，尤其是铁和锰的含量，在蒴果形成期分别可达697.55和38.75 μg·g⁻¹。蒴果形成期铁和锰的含量分别约为肉质茎阶段的7.2倍和8.3倍。（3）在生殖生长阶段，地上部分会排除钠并积累磷、钾、钙、镁、铁、锰、锌、铜和硼。本研究结果将为评价肉苁蓉质量提供科学依据。
