宝乐果挥发油的GC-MS分析

GC-MS analysis of the volatile oil from the fruits of borojoa sorbilis cuter

利用气相色谱-质谱联用仪对宝乐果果实的乙醚萃取物的成分进行分析,并结合计算机检索对其化学成分进行分析和鉴定。结果显示:从宝乐果果实的乙醚萃取物中分离出33个组分,并鉴定出其中22个化合物,占风味挥发油色谱峰面积84.6%。用气相色谱峰面积归一化法测定各组分的相对质量分数,宝乐果果实挥发油中相对质量分数较高的成分分别是正十六烷酸(23.92%)、(E)-9-十八烷烯酸(20.91%)、辛酸(14.94%)、己酸(11.12%)和顺-13-油烯酸甲酯(4.12%)。

The constituents of volatile oil from the fruits of Borojoa sorbilis cuter were extracted by hydrodistillation and analysed by gas chromatography coupled to mass spectrometry（GC-MS）,to determine the chemical composition of the ether fraction and identify their chemotypes by Compound library screening（NIST11.L）.About 33 components were separated and 22 compounds were identified,accounting for 84.6% of the total peak area.The major components quantitatively calculated by area normalization method were： n-Hexadecanoic acid（23.92%）,（E） 9-octadecenoic acid（20.91%）,Octanoic acid（14.94%）,Hexanoic acid（11.12%） and Cis-13-octadecenoic acid,methyl ester（4.12%）.
