HS-SPME/GC-MS法分析香椿芽、叶的挥发性化学成分

采用顶空固相微萃取/气相色谱-质谱(HS-SPME/GC-MS)联用技术分析香椿芽、叶的挥发性化学成分,用峰面积归一化法测定了各挥发性物质的相对质量分数。结果表明:从香椿芽萃取物中鉴定出26个成分,占挥发性组分总质量的74.86%,主要成分是β-石竹烯(质量分数,下同,10.12%),2-氮杂环丙烷乙基胺(10.09%),2-氨氧基丙酸(10.03%),β-香柠檬烯(8.78%),桉-4(14),11-二烯(6.59%),α-荜澄茄油烯(3.02%),α-雪松烯(2.88%),罗勒烯(2.69%),8-异丙烯基-1,5-二甲基-1,5-环癸二烯(2.36%),2-羟基乙基联氨(2.10%),丙基柏木醚(2.07%),羟基乙醛(1.88%),环癸烷醇(1.63%),外-葑醇(1.54%),1,3,8-对?三烯(1.46%),α-姜黄烯(1.18%);从香椿叶萃取物中鉴定出46种成分,占挥发性组分总质量的91.2%,主要成分是β-石竹烯(46.87%),(E)-2-己烯醛(5.29%),α-石竹烯(4.12%),8-异丙烯基-1,5-二甲基-1,5-环癸二烯(3.96%),β-香柠檬烯(3.48%),桉-4(14),11-二烯(3.37%),α-荜澄茄油烯(3.23%),β-波旁烯(2.41%),2-氮杂环丙烷乙基胺(2.23%),α-法呢烯(1.42%),异石竹烯(1.22%),β-萜烯(1.03%)。
