摘要
采用气质联用(GC-MS)技术结合顶空固相微萃取(HS-SPME)分析华盖木Manglietiastrum sinicum叶、花、果的挥发性组分。华盖木3个器官中共鉴定出65种挥发性成分,其中叶挥发性成分有51种,花挥发性成分55种,果实挥发性成分50种;叶、花、果中所鉴定的成分相对含量分别占挥发性成分总量的91.468%、92.801%和91.993%。华盖木不同器官的挥发性成分均以萜类化合物为主,叶、花和果的萜烯类成分相对含量分别为54.853%、64.369%和45.401%;相对含量较高的还有醇类化合物,此外还含有酯类、醛类、酮类、酚类化合物;叶和花中均以榄香醇含量最高,果中以愈创木醇含量最高。华盖木挥发性成分的萜类和醇类化合物在日化、医药等工业领域具有重要用途。
To compare the volatile components in different organs of Manglietiastrum sinicum and provide basic information for the protection and resource utilization of this unique and rare species in China,GC-MS technology combined with HS-SPME was used to analyze the volatile components of M.sinicum leaves,flowers,and fruits.A total of 65 components were identified in three organs of M.sinicum,including 51 compounds in leaves,55 compounds in flowers,and 50 compounds in fruits.The relative contents of the identified components in the three organs accounted for 91.468%,92.801%,and 91.993% of the total volatile components,respectively.The volatile components in three organs of M.sinicum are mainly terpenoids,with terpenoid content in leaves,flowers,and fruits being 54.853%,64.369%,and 45.401%,respectively.Alcohol compounds are also present in high concentrations,it also contains esters,aldehydes,ketones,and phenols.Both leaves and flowers have the highest content of elemol,while fruits have the highest content of guaiol.The terpenes and alcohol compounds in the volatile components of M.sinicum have important applications in industrial fields such as daily chemical and pharmaceutical industries.
