摘要
经HNO3/H2O2湿法微波消解制样,利用全谱直读电感耦合等离子原子发射光谱法(ICP-OES),分析测定了青藏高原地区产藏雪莲水母雪兔子中的矿质元素。结果显示,藏雪莲水母雪兔子中含有K、Ca、P、Mg、Al、S、Fe、Si、Na、Mn、Ti、Sr、Ba、B、Zn、Cu、Cr等17种矿质元素,定量分析结果相对标准偏差RSD值在0.60%～7.25%之间。与普通食物相比较,藏雪莲水母雪兔子中人体必需元素Ca、Mg、Fe、Mn的含量非常丰富,分别为1724.4 mg.(100 g)-1、386.5mg.(100 g)-1、165.5 mg.(100 g)-1、8.54 mg.(100 g)-1。分析结果可为藏雪莲水母雪兔子的相关研究提供参考。
Using wet microwave digestion procedure with HNO3/H2O2 to prepare samples,the mineral elements in Saussurea medusa Maxim.from the Qing-Tibet plateau were completely determined and analyzed by inductively coupled plasma optical emission spectrometer（ICP-OES）.The results showed there were 17 mineral elements in Saussurea medusa Maxim..They were K,Ca,P,Mg,Al,S,Fe,Si,Na,Mn,Ti,Sr,Ba,B,Zn,Cu and Cr.The RSD of the determining result was between 0.60% and 7.25%.Compared to daily foods,the Saussurea medusa Maxim.is very rich in Ca,Mg,Fe and Mn,which are parts of necessary metals of the human body.Their qualities were 1724.4 mg·（100 g）-1,386.5 mg·（100 g）-1,165.5 mg·（100 g）-1 and 8.54 mg·（100 g）-1,respectively.These results provided some reference to relative research of Saussurea medusa Maxim..
