摘要
采用气相色谱-质谱联用技术(GC-MS)分别对在超临界状态下松脂与甲醇反应产物进行分析,共分离出49个峰,鉴定出45种化合物,反应产物主要为甲酯类、烯烃类化合物,还有较少量的芳香烃类、烷烃类和醇酮类等化合物。甲酯类的主要成分为脱氢枞酸甲酯、1,2,3,4,4a,9,HUANG Sen-li10,10a-八氢-1,4a-二甲基-1-菲羧酸甲酯及二氢异海松酸甲酯,GC含量分别为24.48%、5.35%、5.15%;烯烃类主要成分为对-薄荷烯、1-甲基-3-(2-甲基-1-丙烯基)-环己烯、(+)-环异洒剔烯、长叶烯,GC含量分别为14.99%、7.88%、4.15%、6.71%。
The reaction products from pine gum with methanol under supercritical conditions were analyzed by gas chromatography-mass spectrometry（GC-MS）,using DB-5 MS flexible quartz capillary column.Forty-nine peaks were separated and forty-five compounds were identified.The results showed that reaction products mainly included methyl esters and alkenes,slightly aromatic hydrocations,alkanes and alcohols.Methyl esters included methyl dehydroabietic acid（24.48%）,1,2,3,4,4a,9,10,10a-octaahydro-1,4-dimethyl-1-methyle phenanthrenecarboxylic acid（5.35%）,and methyl isopimarenoic acid（5.15%）,while alkene included p-mentha（14.99%）,1-methyl-3-（2-methyl-1-propenyl）-cyclopentane（7.88%）,（＋）-cycloisosativene（4.15%）,and longipinene（6.71%）.
