摘　　要：采用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),全面详细地分析测定西藏绿萝花中的矿质元素,共检出K、P、Ca、Mg、S、Al、Si、Fe、Na、Mn、Zn、Sr、B、Ba、Cu、Ti等16种矿质元素。分析结果相对标准偏差(RSD)值,除Ti元素外,其余15种都在4%以内;加标回收率在90.3%～110.9%之间,其中10种元素在(100±5)%范围内。绿萝花中所含人体常量元素K、P、Ca、Mg、S、Na等的质量分数分别为0.66%、0.40%、0.27%、0.23%、0.17%和0.004%;微量元素Fe、Zn、Cu、Si、Mn、B等的质量分数分别为48.4、30.8、6.5、151.0、36.3、16.5 mg/kg。By wet digestion procedure with HNO3/H202 to prepare samples, the mineral elements in Scindapsus aureus （Linden ex Andre） Engler were completely analyzed by inductively coupled plasma optical emission spectrometer （tCP-OES）. The results showed that there were 16 mineral elements including K, P, Ca, Mg, S, Al, Si, Fe, Na, Mn, Zn, St, B, Ba, Cu and Ti in Scindapsus aureus. Except that of Ti, the RSD of other mineral elements were less than 4 %. The recovery rate was between 90. 3% and 110.9 %. Among them, those of 10 mineral elements were within （ 100 ±5 ） %. The mass fraction of such necessary macrometals in the human body, such as K, P, Ca, Mg, S and Na, were 0.66 %, 0.40 %, 0.27 % , 0.23 % , 0.17 % and 0. 004 % , respectively. The contents of microminerals such as Fe, Zn, Cu, Si, Mn, and B, were 48.4, 30.8, 6.5, 151,36. 3 and 16.5 mg/kg, respectively.
