【摘要】 采用顶空固相微萃取（HS-SPME）和气相色谱质谱联用（GC-MS）的方法，分析香囊贴中的挥发性成分。通过单因素考察，以出峰数为优选指标，筛选出最佳HS-SPME条件：PDMS萃取头、样品量0.3 g、萃取温度110℃、萃取时间20 min。该萃取条件下，HS-SPME-GC-MS联用共测得香囊贴成分36种，占挥发性成分的88.17%，其中相对峰面积百分比5%以上的有5种成分，分别是α-松油醇（25.50%）、（+）-花侧柏烯（10.62%）、4-萜烯醇（9.43%）、芳樟醇（8.19%）、乙酸芳樟酯（6.96%）。HS-SPME-GC-MS方法能对香囊贴进行挥发性成分分析，为香囊贴产品开发和质量控制提供依据。更多还原

【Abstract】 Headspace solid-phase microextraction(HS-SPME) combined with gas chromatography-mass spectrometry(GCMS) was used to analyze the volatile components in the sachet patch. Single-factor experiment was conducted to determine the optimal HS-SPME conditions with the number of peaks as the index. The optimized conditions were selected as follows, PDMS fiber, sample amount of 0.3 g, extraction temperature of 110 ℃, and extraction time of 20 min. With the above extration conditions, a total of 36 components in the sachet patch were identified by HS-SPME-GC-MS, accounting for 88.17% of the volatile components. Among them, there were 5 components with a relative peak area content more than 5%, which were α-pinacol(25.50%),(+)-floral siderene(10.62%), 4-terpinenol(9.43%), linalool(8.19%), and linalyl acetate(6.96%). The method of HS-SPME-GC-MS was able to analyze the volatile components of the sachet patch, providing a basis for the product development and quality control of the sachet patch.更多还原
