摘要
目的:评价不同组织器官的挥发性成分的累积分布。方法:利用顶空固相微萃取(HS-HPME)结合气相色谱-质谱联用(GC-MS)对凹叶厚朴不同组织器官(叶芽、根皮、茎皮、枝皮、叶、果皮和种子)的挥发性成分进行分析。结果:这些组织的挥发性成分主要是α-芳樟醇0.21%～4.92%、α-石竹烯7.48%～38.71%、β-石竹烯1.53%～14.43%、4(14),11-桉叶二烯0.15%～10.02%、β-花柏烯0.56%～10.68%、石竹烯氧化物1.68%～36.01%、α-桉叶醇1.56%～33.79%和β-桉叶醇0.19%～28.89%,精油产率为0.12%～0.96%。结论:植株的叶芽、根皮、茎皮、枝皮、叶、果皮和种子挥发精油的产率、挥发性成分以及这些成分的累积含量差异显著。
Objective： To evaluate accumulation of the volatiles of the different tissues in Magnolia officinalis. Method： The volatiles of leaf buds, root skins, barks, twig skins, leaves, pericarps and seeds of M. officinalis were analyzed using headspace solid phase micro-extraction （HS-SPME） following by capillary gas chromatography coupled to mass spectrometry （GC-MS）. Result： The volatiles were α-linalool 0.21% -4.92% ,α- caryophyllene 7.48%-38.71% , fl-caryophyllene 1.53%-14.43% , eudesma-4 （ 14 ） , ll-diene 0.15%- 10.02% , β-chamigrene 0.56% -10.68% , caryophyllene oxide 1.68% -36.01% , α-eudesmol 1.56% -33.79% and β-eudesmol 0. 19%-28.89%. The yields of essential oils in the different tissues were 0.12%-0. 96%. Conclusion： The essential oil, the volatiles composition and their accumulation content of leaf buds, root skins, barks, twig skins, leaves, pericarps and seeds of M. officinalis were significantly different.
