采用顶空固相微萃取气质联用(HS-SPME-GC/MS)法分析检测香料槟榔片的挥发性香味组分,探讨萃取时间和萃取温度对所鉴定出的化合物数量及其质量分数的影响,确定固相微萃取的优化条件为:萃取时间30min,萃取温度60℃。此时槟榔色谱共分离得到35种化合物,可鉴别出29种物质,其主要组分是反式茴香醚(W=25.573%)、己酸(W:17.227%)、肉桂醛(W=11.658%)、4-甲氧基安息香醛(W=4.513%)、十二烷酸(W=4.463%)和己醛(W:3.459%)等。
Aroma components of betelnut were analyzed by HS-SPME and GC-MS. Effect of extraction time and temperature on the number of identified compounds and total mass fraction were also discussed under the optimalized SPME conditions : extraction time 30 min, extraction temperature 60℃. 35 kinds of compounds were separated by the gas chromatography and 29 kinds of these can be deter- mined under above conditions with the results as follows: the main components were benzene, 1-methoxy-4-(1-propenyl) (w = 25. 573% ) ,hexanoic acid( w = 17. 227% ) ,2-propenal,3-phenyl(w = 11. 658% ) ,benzaldehyde,4-methoxy( w =4. 513% ) , dodecano- ic acid ( w = 4. 463 % ) , Hexanal ( w = 3. 459 % ) , et al.
