摘　　要：采用水蒸气蒸馏法从藏红花花瓣和雄蕊中提取挥发油,用GC-MS技术结合计算机检索对其二者化学成分进行分离和鉴定,用色谱峰面积归一化法计算各组分的相对含量。花瓣中共鉴定出16种化合物,主要成分为正二十六烷(11.60%)、正十五烷(11.31%)、棕榈酸甲酯(10.82%)、油酸甲酯(10.35%)、2,4-二叔丁基苯酚(9.63%)、亚油酸甲酯(7.18%)、藏红花醛(5.66%);雄蕊中共鉴定出20种化合物,主要成分为油酸甲酯(30.83%)、亚油酸甲酯(24.12%)、环己醇(16.80%)、硬脂酸甲酯(12.88%)、棕榈酸甲酯(8.97%)、花生酸甲酯(1.18%)、苯并噻唑(1.01%)。The volatile oils were extracted from petals and stamens of Crocus sativus by steam distillation.The chemical compounds were separated and identified by capillary GC-MS method.The relative content of each component was calculated by area normalization.Sixteen compounds were identified from petals of C.sativus.The main components were n-hexacosane（11.60%）,n-pentadecane（11.31%）,palmitic acid methyl ester（10.82%）,oleic acid methyl ester（10.35%）,2,4-ditertiary butyl phenol（9.63%）,linoleic acid methyl ester（7.18%） and safranal（5.66%）.Twenty compounds were identified from stamens of C.sativus.The main components were oleic acid methyl ester（30.83%）,linoleic acid methyl ester（24.12%）,cyclohexanol（16.80%）,stearic acid methyl ester（12.88%）,palmitic acid methyl ester（8.97%）,eicosanoic acid methyl ester（1.18%） and benzothiazole（1.01%）.
