中文摘要：
采用ICP-AES法测定两种肉苁蓉及其提取物中11种矿质元素,结果表明：肉苁蓉中Mn,K,Ca,Mg,Na含量（μg.g-1）显著高于管花肉苁蓉,分别为17.70,16 278.03,1 947.25,1 662.76,106.79;肉苁蓉50%甲醇提取物中Fe,Cu,P含量为水提物的1.5倍、2.4倍、1.1倍,Mn,Zn,K,P,Mg,Na含量为100%甲醇提取物的3.8倍、1.2倍、1.6倍、2.3倍、2.2倍、1.1倍;管花肉苁蓉50%甲醇提取物中Cu和P含量为水提物的1.6倍和1.2倍,Mn,Zn,K,P,Mg,Na,Al含量为100%甲醇提取物的2.0倍、1.6倍、1.6倍、1.4倍、1.8倍、1.2倍、1.2倍;肉苁蓉和管花肉苁蓉内矿质元素在50%甲醇中的溶出率分别是60.79%～83.10%和44.58%～83.84%,且Mn,Zn,K,P,Ca,Na,Al的溶出率显著高于水和100%甲醇提取。此研究为高效利用肉苁蓉药材中的矿质元素提供了科学依据。
英文摘要：
Determination of Fe,Zn,Cu,K,P,Ca,Mg,Na,B and Al in cistanche and its extractives was carried out by the inductively coupled plasma atomic emission spectrometry（ICP-AES）.The results showed that（1） the contents of Mn,K,Ca,Mg and Na in cistanche deserticola Y.C.Ma were 17.70,16 278.03,1 947.25,1 662.76,and 106.79 respectively（μg·g-1）,much higher than in Cistanche tubulosa（Schrenk） Wight;（2） the contents of Fe,Cu and P in 50% methanol extract of Cistanche deserticola were 1.5,2.4,and 1.1 times that of aqueous extract respectively,the contents of Mn,Zn,K,P,Mg and Na were 3.8,1.2,1.6,2.3,2.2,and 1.1 times that of methanol extract respectively;（3） the contents of Cu and P in 50% methanol extract of Cistanche tubulosa were 1.6 and 1.2 times that of aqueous extract,the contents of Mn,Zn,K,P,Mg,Na and Al were 2.0,1.6,1.6,1.4,1.8,1.2,and 1.2 times that of methanol extract respectively;（4） the leaching rate of 11 mineral elements in Cistanche deserticola and Cistanche tubulosa were 60.79%~83.10% and 44.58%~83.84% in 50% methanol respectively,and the leaching rate of Mn,Zn,K,P,Ca,Na and Al were much higher than in water and 100% methanol extracted.The research provided the basic data of mineral element in comparative study on Cistanche deserticola and Cistanche tubulosa,and provide scientific basis for efficient utilization of mineral element in cistanche.
