金钱松叶片挥发油成分的GC-MS分析

为分析金钱松Pseudolarix amabilis叶片挥发油的化学成分,采用水蒸气蒸馏法提取金钱松叶片挥发油,利用气相色谱-质谱(GC-MS)联用仪对金钱松叶挥发油成分进行分析,以面积归一法计算各个化学成分的相对含量。结果表明:从挥发油中检测出49个化合物,占挥发油总量的93.35%。其主要成分是:(+)-α-蒎烯(31.72%),石竹烯(18.57%),β-瑟林烯(6.16%),α-衣兰油烯(5.71%),β-榄香烯(5.64%),α-愈创木烯(5.28%),β-桉叶烯(3.36%)等,占挥发油总量的82.92%。可为金钱松的深入研究及开发利用提供了科学依据。

hemical components of volatile oil from the leaves of Pseudolarix amabilis using GC-MS

To analyze the chemical components of volatile oil from the leaves of Pseudolarix amabilis，volatile oil from the leaves was extracted by steam distillation and the components were analyzed by gas chromatography-mass spectrometry （GC-MS） using peak area normalization methods. Results revealed 49 compounds which accounted for 93.35% of the chemical composition of the essential oil. The main compounds were （+）-α-pinene （31.72%），caryophyllene（18.57%），β-selinene（6.16%），α-muurolene（5.71%），β-elemene（5.64%），α-guaiene （5.28%），and β-eudesmol （3.36%） which accounted for 82.92% of the total peak area. This study could help provide a scientific basis for further research and development of P. amabilis. ［Ch, 1 fig. 1 tab. 12 ref. ］
