摘要
利用超声辅助水蒸气蒸馏法对青海省窄叶鲜卑花叶片和果穗的挥发油成分进行提取,通过气相色谱质谱联用(GC-MS)技术对其化学成分进行分析鉴定,经气质联用仪计算机质谱数据系统检索,叶片挥发油鉴定出87个组分,果穗挥发油鉴定出92个组分,采用峰面积归一化法来确定各组分相对含量,得到叶片挥发油的鉴定成分占挥发油总量的97.53%,果穗挥发油的鉴定成分占挥发油总量的97.12%,两者挥发油组分种类较多,主要组分大致相似,包括:邻苯二甲酸二丁酯、正二十五烷、二十四烷、(E)-罗勒烯酮、对甲氧基肉桂酸辛酯、芳樟醇、香叶醇等,以酯类、烷烃类、脂肪酸、萜类物质为主。
The volatile oil components from leaves and ears of Sibiraea angustata in Qinghai Province were extracted by ultrasonic assisted steam distillation. The components of volatile oil were identified by gas chromatography-mass spectrometry (GC-MS). The data were retrieved by computer mass spectrometry data system. The peak area normalization method was used to determine the relative content of each component. The identified components of the volatile oil of the leaves accounted for 97.53% of the total volatile oil, and the identified components of the volatile oil of the ear accounted for 97.12% of the total volatile oil. The volatile oil components of the two species were more and the main components were similar which include Dibutyl phthalate, Pentacosane, Tetracosane, (E)-Ocimenone, 2-Ethylhexyl 3-(4-methoxyphenyl) acrylate, Linalool, Geraniol, etc., and mainly compose of esters, alkanes, fatty acids, and terpenoids.
