细叶石仙桃地上部分挥发性成分的HS-SPME-GC-MS分析

目的:研究细叶石仙桃地上部分的挥发性成分。方法:采用顶空固相微萃取和气相色谱-质谱联用技术(HS-SPME-GC-MS)并结合保留指数法测定样品中的挥发性成分;采用峰面积归一化法计算各挥发性成分的相对百分含量。结果:从细叶石仙桃地上部分共分离鉴定出20个化学成分,占总挥发性成分的98.35%。其中,植酮(26.56%)、R,R]-2,3-丁二醇(11.99%)、E-15-十七碳烯醛(8.91%)、十七烷(5.11%)、2,3-丁二醇(4.85%)、棕榈酸(4.80%)、十六烷(3.91%)、菲(3.78%)、植烷(3.63%)、广藿香醇(3.60%)和亚油酸甲酯(3.01%)是主要的挥发性成分。结论:本试验结果可为细叶石仙桃的进一步开发利用提供依据。

Analysis of Volatile Components in the Aerial Parts of Pholidota cantonensis by HS-SPME-GC-MS

OBJECTIVE:To study the volatile constituents in the aerial parts of Pholidota cantonensis.METHODS:The volatiles were analyzed by head-space solid micro-extraction coupled with GC-MS(HS-SPME-GC-MS)and Kovats indices.The relative content of each component was calculated by peak area normalization measurements.RESULTS:20 compounds were identified and accounted for 98.35% of the total volatile components.The main components were perhydrofarnesyl acetone(26.56%),R,R]2,3-butanediol(11.99%),E-15-heptadecenal(8.91%),heptadecane(5.11%),2,3-butanediol(4.85%),n-hexadecanoic acid(4.80%),hexadecane(3.91%),phenanthrene(3.78%),phytan(3.63%),patchouli alcoho(l3.60%)and linoleic acid methyl ester(3.01%).CONCLUSION:The study can provide reference for the further development and application of P.cantonensis.
