摘　　要：利用水蒸气蒸馏法提取鸡嗉子叶的挥发性成分,采用气相色谱-质谱联用(GC-MS)技术对其化学成分进行分离分析,并用色谱峰面积归一化法测定各成分的相对含量.通过计算机检索,鉴定出51个化学成分,其中主要成分为5,6,7,8,9,10-六氢-6,7,8,9-四氧合-2-吩嗪甲酸(17.357%)、十八醛(11.042%)、2-氟代-N-[2-(2-糠基氨基)-乙氧羰基]苯甲酰胺(9.371%)、二十烷(6.970%)、1-甲基-5硝基吡唑(4.589%)、β-紫罗兰酮(2.441%)、10-甲基二十烷(3.463%)、乙酸橙花叔醇酯(2.058%).The chemical components of the essential oil in the leaves of Dendrobenthamia capitata （ Wall. ） Hutch. were extracted by water stream distillation and analyzed by GC - MS. The relative contents of the chemical components were calculated by the chromatographic peak area normalization method. Fifty - one chemical compounds were identified from the essential oil of Dendrobenthamia capitata （Wall.） Hutch. The main compounds were 5,6,7,8,9,10 - hexahydro - 6,7, 8,9 - tetraoxo - 2 - phenazinecarboxylicacid （ 17. 357% ）, octadecanal （ 11.042% ） ,2 - fluoro - N - [ 2 - （2 - furfurylami- no） - 2 - oxoethyl ] benzamide （9. 371% ）, eicosane （6. 970% ）, 1 - methyl - 5 - nitropyrazole （4. 589% ）, β - ionone （2. 441% ） ,10 -methyl eicosane （3. 463% ） ,and nerolidyl acetate（2. 058% ）.
