新鲜山矾花头香成分的研究

Studies of Chemical Constituents of Top Note in Fresh Flowers of Symplocos Caudata Wall.ex A.DC.

用 60H型硅胶吸收刚采摘的鲜山矾花的头香成分 ,用无水乙醚洗脱 ,高纯氮吹出乙醚浓缩 ,所得的鲜山矾花的头香成分浓缩液用气相色谱 -质谱 (GC -MS)法分离并分析鉴定其成分及质量分数 ,共鉴定出 2 2个化合物 ,其中所鉴定的鲜山矾花的头香成分的组分占挥发性成分总峰面积的 91 2 0 %。它们是 :w (双花醇 ) =2 5 0 1%、w(反式 氧化芳樟醇 ) =6 2 4%、w(顺式 氧化芳樟醇 ) =1 0 8%、w(L 芳樟醇 ) =18 98%、w (紫丁香醇 ) =2 3 7%、w(紫丁香醛 ) =0 5 6%、w(月桂醇 ) =0 2 5 %、w(氧化橙花醇 ) =3 0 9%、w(乙苯 ) =2 0 0 %、w(2 ,6 二甲基 3 ,7 辛二烯 2 ,6 二醇 ) =10 17%、w(3 ,4,5 三甲氧基甲苯 ) =7 3 5 %、w (4 甲基 2 ,6 二叔丁基 4 羟基 2 ,5 环己二烯 1 酮 ) =1 0 9%、w(2 ,6 二叔丁基对苯醌 ) =0 41%、w(2 ,6 二叔丁基对甲苯酚 ) =2 61%、w(3 ,5 二叔丁基 4 羟基苄醇 ) =0 3 9%。

The top note in fresh flowers of Symplocos Caudata Wall.ex A.DC. was collected by adsorption with silica gel 60H.After eluting with absolute ether,and removing ether by blowing N_2,the concentrated extract obtained was analyzed using gas chromatography-mass spectrometry.22 compounds were identified.91.20% of the peak area of the volatile matters is contributed by the components of top note in fresh flowers of Symplocos Caudata Wall.ex A.DC.They are shuanghuaol (25.01%),trans-linaloloxide (6.24%),cis-linaloloxide (1.08%),L-linalool (18.98%),lilac alcohol(2.37%),lilac aldehyde (0.56%),lauryl alcohol (0.25%),nerol oxide (3.09%),ethylbenzene (2.00%),2,6-dimethyl-3,7-octadiene-2,6-diol(10.17%),3,4,5-trimethoxytoluene (7.35%),2,6-di(t-butyl)-4-hydroxy-4-methyl-2,5-cyclohexadien-1-one (1.09%),2,6-di-tert-butylquinone (0.41%),4-methyl-2,6-di-tert-butylphenol(2.61%),3,5-di-tert-butyl-4-hydroxybenzyl alcohol (0.39%).
