| 摘 要： | 通过顶空固相微萃取结合气-质联用技术,分析检测中药良姜的挥发性组分,研究萃取时间、萃取温度对良姜挥发性物质数量的影响。结果表明,当萃取时间为35 min,萃取温度为60℃时共检出53种化学组分,其中52种物质可鉴别。其主要组分是萜烯类化合物(w=40.238%)、桉树脑(w=23.066%)、α-松油醇(w=8.522%)、β-蒎烯(w=3.618%)和莰烯(w=3.001%)等。

| Abstract: | Headspace solid phase micro-extraction coupling with gas chromatography-mass spectrometry(HS-SPME/GC-MS) was used to analyze volatile compounds of galangal.Effect of extraction time and temperature on the amount of identified compounds was discussed under the optimal SPME conditions:35 min extraction time,60 ℃ extraction temperature.53 kinds of compounds were separated by the gas chromatography and 52 kinds of these can be determined under certain conditions above with the results as follows:the main component was terpenes(40.238%),and other compounds of high content were eucalyptol(23.066%),p-menth-1-en-8-ol(8.522%),β-pinene(3.618%),camphene(3.001%),and so on. |
