摘要: 利用同时蒸馏萃取法(SDE)提取白兰花中的挥发性组分。HP-5柱和Supelco-10-10柱上用气相气谱-质谱法分别检出103个和96个峰。其中有61个峰质谱检索结果相同,它们占总峰面积的77.2%。含量较高的组分有:芳樟醇(70.21%和72.33%),2-甲基丁酸甲酯(4.11%和3.96%),2-甲基丁酸乙酯(2.28%和2.73%),(Z)-3,7-二甲基-1,3,6-辛三烯(2.30%和2.45%),(E)-3,7-二甲基-,3,6-辛三烯(1.98%和2.23%),甲基丁香油酚(2.03%和1.86%),1-乙烯基-1甲基-2,4-二(1-甲基乙烯基)-环已烷(1.13%和1.16%),桉叶油素(1.02%和1.078%)。从化合物的种类来看,主要为烯类(15种),酯类(13种),醇类(9种),醛类(5种),烷类(4种),酚类(2种),酮类(1种)等。

Abstract: The volatile compounds of Michelia a lba DC were collected by using a simul taneous distillation and ex-traction(SDE)equipment.The chemical compositio n of the enriched volatile was examin ed by means of capillary gas chromatogrphy(GC)combinedwith GC -mass spectrometry(MS ).sixty one constituents of the volatile were prelimi-narilyidentifiedbyGC -MS,whicham ountedto77.2%ofthetotalpeakarea.Themainconstituents ofthevolati lewere linalool(70.21%and72.33%);2-methyl -butanoic acid,methyl ester(4.11%and3.96%);2-methyl -bu-tanoic acid,ethyl ester(2.28%and2.73%);(Z)-3,7-dimethyl -1,3,6-octatriene(2.30%and2.45%);(E)-3,7-dimethyl -1,3,6-octatriene(1.98%and2.23%);methyleugenol(2.03%and1.86%);1-ethenyl -1-methyl -2,4-bis(1-methylethenyl)-cyclohesane(1.13%and1.16%)and eucalyptol(1.02%and1.08%).The compound classes consisted of olefines(15),esters(13),alcohols(9),aldehydes(5),alkhls(4),hydroxybenzenes(2),and ketone(1).
