中文摘要：

通过顶空固相微萃取结合气一质联用技术，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35min，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（伽=3．618％）和莰烯（W=3．001％）等。

英文摘要：

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 separa- ted 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-l-en-8-ol （8. 522% ）, 13-pinene （ 3. 618% ）, eamphene （ 3. 001% ）, and so on.
