摘　　要：采用水蒸气蒸馏法从火棘叶中提取挥发油,利用气相色谱-质谱(GC-MS)联用方法分析火棘叶挥发油化学成分,并以面积归一法测定各成分的相对含量。从火棘叶挥发油中共鉴定出69种化合物,占挥发油总量的80.52%,主要成分为(-)-b-杜松烯(22.62%)、植物醇(19.90%)、二环倍半水芹烯(5.95%)、β-桉叶醇(5.78%)、1,2,3,4,4a,7-六氢-1,6-二甲基-4-(1-甲基乙基)-萘(2.78%)、表圆线藻烯(2.34%)等。The volatile oil from the leaves of Pyracanthafortuneana was extracted by water-steam distillation and the chemical component was determined by GC-MS. The relative contents of the chemical component was determined with peak area normalization method. Sixty-nine compounds accounting for 80. 52% of total volatile oil were identified. The major constituents were identified as （-） -b-cadinene （22.62%）, plant alcohol（ 19.90% ）, bicyclosesquiphellandrene （5.95 % ） ,β-eudesmol （5.78%）, 1,2,3,4,4a,7- hexahydro-1,6 -dimethyl-4 - （ 1 -methylethyl） -naphthalene （ 2. 78 % ）, and epizonarene （ 2. 34% ）.
