零陵香挥发性成分的SPME-GC/MS分析

目的采用固相微萃取-气相/质谱(SPME-GC/MS)联用技术分析零陵香挥发性成分。方法利用75μm碳分子筛/聚二甲基硅氧烷(75μm CAR/PDMS)、65μm二乙烯基苯/聚二甲基硅氧烷(65μm DVB/PDMS)、85μm聚丙烯酸酯(85μm PA)和100μm聚二甲基硅氧烷(100μm PDMS)共4种不同涂层的固相微萃取(SPME)萃取头,在最佳条件下,分别对零陵香挥发性成分进行萃取,并通过气相/质谱(GC/MS)联用分析检测其化学成分。结果零陵香挥发性成分SPME关键参数为:萃取温度80℃、时间50 min。4种萃取头共检出零陵香挥发性成分10类103种,酚类、酯类和烃类化合物是...

Summary:目的采用固相微萃取-气相/质谱(SPME-GC/MS)联用技术分析零陵香挥发性成分。方法利用75μm碳分子筛/聚二甲基硅氧烷(75μm CAR/PDMS)、65μm二乙烯基苯/聚二甲基硅氧烷(65μm DVB/PDMS)、85μm聚丙烯酸酯(85μm PA)和100μm聚二甲基硅氧烷(100μm PDMS)共4种不同涂层的固相微萃取(SPME)萃取头,在最佳条件下,分别对零陵香挥发性成分进行萃取,并通过气相/质谱(GC/MS)联用分析检测其化学成分。结果零陵香挥发性成分SPME关键参数为:萃取温度80℃、时间50 min。4种萃取头共检出零陵香挥发性成分10类103种,酚类、酯类和烃类化合物是零陵香挥发性成分的主要化学类型。4种萃取头检出共有成分6种,分别为葫芦巴内酯、二氢猕猴桃内酯、(+)-雪松醇、植酮、菲、3-氨基-4,5-二甲基-2(5H)-呋喃酮;各萃取头中75μm CAR/PDMS萃取头检出挥发性成分数量最多。结论本文首次采用SPME-GC/MS对零陵香挥发性成分进行测定。该方法简单、快速、准确,为零陵香物质基础研究提供参考借鉴。

Objective To analyze the volatile constituents of Linglingxiang( Lysimachia foenumgraecum, Hance, Holy Basil) by applying solid phase microextraction-gas chromatography-mass spectrometry( SPME-GC/MS). Methods The heads of solid phase microextraction( SPME) with 4kinds of different coating,75 μm CAR/PDMS,65 μm DVB/PDMS,85 μm PA and 100 μm PDMS,were used to extract the under the best extraction condition,and then these volatile constituents were detected by using gas chromatography-mass spectrometry( GC-MS). Results The key parameters ofSPME for extracting volatile constituents from Linglingxiang were as follows: temperature was 85℃ and extracting time was for 50 min. A total of 10 types including 103 kinds of volatile constituents were identified by 4 different SPME extraction heads,and phenols,esters and hydrocarbons were main chemical types of volatile
