摘 要:目的研究蒙古鸦葱Scorzonera mongolicaMaxim.挥发油和无机元素的成分及相对含量。方法采用索氏提取法提取蒙古鸦葱挥发油,通过微波消解得到无机元素样品。采用GC/MS和ICP/MS对其挥发油和无机元素进行分析。结果确定了挥发油中的13种成分,占挥发油总量的93.43%,均为首次报道;测定了27个无机元素,元素的含量顺序为:Ce,K,Al,Ca,Fe,La,Mg,Na,P,Ga,Mn,Ba,Zn,B,V,Cr,Cu,Ni,Pb,Th,As,Co,Se,Sr,Mo,Cd和Hg。结论挥发油中两种最主要成分为三十一烷(34.75%)和何帕-22(29)-烯-3β-醇(21.47%),占挥发油总量的56.22%。27个无机元素中Ce,K,Al和Ca含量最高,微量元素Ce,Ga,Mn和Zn含量较高。Objective To study the volatile oils and inorganic elements of Scorzonera mongolica Maxim. Methods Volatile oils of Scorzonera mongolica Maxim. were extracted by Suo recovery ( hot refluxing) method and analysed by GC-MS. Sample of inorganic elements was digested with microwave digestion system and measured by ICP-MS. Results 13 constituents of volatile oil were determined, and identified up to 93.43% of the constituents. 27 kinds of inorganic elements were determined, they were Ce, K, A1, Ca, Fe, La, Mg, Na, P, Ga, Mn, Ba, Zn, B, V, Cr, Cu, Ni, Pb, Th, As, Co, Se, Sr, Mo, Cd and Hg. Conclusion The main components of volatile oil are Hentriacontane ( 34.75% ) and A'- neogammacer-22 ( 29 ) -en-3β-ol ( 21.47% ). The main inorganic elements are Ce, K, A1, Ca and Fe. The main microelements are Ce, Ga, Mn and Zn.
