摘要: 建立顶空固相微萃取-气相色谱-质谱结合自动解卷积技术检测葛根中挥发性物质的分析方法,以总峰面积和峰数目为考察指标,通过单因素试验和正交试验对不同萃取条件进行优化。结果表明,萃取温度对峰数目和总峰面积的影响较大,较佳萃取条件为样品量3.0 g、50/30 μm DVB/CAR/PDMS萃取头、萃取温度90 ℃、平衡时间13 min、萃取时间50 min、解吸时间5 min;在此条件下,鉴定出葛根挥发性成分67 种,分别为酯类11 种、醛类22 种、醇类9 种、酮类5 种、萜烯类8 种和12 种其他类物质。

Abstract: A method for the determination of volatile compounds in Pueraria Radix by headspace solid-phase microextraction (HS-SPME)-gas chromatography-mass spectrometry (GC-MS) combined with the automatic deconvolution software automated mass spectral deconvolution and identification system (AMDIS) was established. Total peak area and number of peaks were used as response variables to optimize the extraction conditions of HS-SPME by one-factor-at-atime and orthogonal array design methods. The results showed that the extraction conditions were optimized as follows: 3.0 g of sample, equilibration time 13 min, extraction for 50 min at 90 ℃ using 50/30 μm DVB/CAR/PDMS fiber and then desorption for 5 min. Under these conditions, 67 volatile components were identified, including 11 esters, 22 aldehydes, 9 alcohols, 5 ketones, 8 terpenes, and 12 others.

Key words: headspace solid-phase microextraction (HS-SPME), gas chromatography-mass spectrometry (GC-MS), Pueraria Radix, volatile compounds, orthogonal array design
