柽柳挥发油成分及无机元素的GC/MS和ICP-MS分析

Analysis of Volatile Oils and Inorganic Elements of Tamarix chinensis Lour. by GC/MS and ICP-MS

采用GC/MS方法分析鉴定了用索氏提取法获得的柽柳挥发油中的26种成分,占挥发油总量的91.0%。4种主要成分为十六酸甲脂(29.20%)、十八碳二烯酸(20.88%)、9-十八碳烯酸甲酯(12.31%)和β-维生素E(7.65%),占挥发油的70.0%。采用ICP-MS法测定了微波消解法得到的柽柳无机元素样品中的无机元素成分,共检出27个元素,元素含量高低顺序为:K、Na、Ca、Mg、P、Ce、Fe、Al、La、B、Zn、Ni、Cu、Cr、Ga、Mn、V、Se、Ba、Pb、Sr、Mo、As、Th、Co、Cd、Hg,微量元素Ce、Fe、Zn、Ni、Cr含量较高。

The volatile oils of medicinal plant Tamarix chinensis Lour. was extracted by Suorecovery method and analyzed by GC/MS. 26 components from the volatile oils were identified according to the library search. 4 main constituents were hexadecanoic acid methyl ester （29.20%）, 11, 14-octadecadienoic acid methyl ester （20.88%）, 9-octadecenoic acid methyl ester （12.31%） and β-toeopherol （7. 65%）, which accounted for 70. 0% of total volatile components. The organic elements of Tarnari：c chinensis Lour. was determined by ICPMS. 27 organic elements including K, Na, Ca, Mg, P, Ce, Fe, Al, La, B, Zn, Ni, Cu, Cr, Ga, Mn, V, Se, Ba, Pb, Sr, Mo, As, Th, Co, Cd and Hg are determined. Among them, the trace elements of Ce, Fe, Zn, Ni, Cr and Mn are necessary for the health of human beings. The analysis results can provide scientific evidence for evaluating the chinese traditional medicine quality of Tarnarix chinensis Lour..
