藏红花花瓣和雄蕊挥发油化学成分GC-MS分析及比较

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％)、环已醇(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％).

Analysis and Comparison of the Volatile Oils from Crocus sativus by GC-MS

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%).
