摘  要：
采用气质联动技术对秦岭林区华山松健康木、枯萎木针叶、树脂和韧皮部组织内挥发性物质的组成、含量和生物活性进行了分析。结果表明:华山松针叶、树脂和韧皮部组织内的挥发性成分主要由单萜、倍半萜和二萜组成,其中以α-蒎烯、β-蒎烯、乙酸-龙脑酯、β-石竹烯、α-石竹烯、α-杜松醇、异杜松醇、萜烯醇、杜松二烯为主;华山松针叶、树脂、韧皮部组织内挥发性物质在组成和含量上均有差异,其中以针叶中挥发性物质成分最丰富,其次是韧皮部组织,而树脂的成分则更纯;同时华山松健康木与枯萎木间挥发性物质的种类和含量也具有明显差异。

摘  要：
In this paper,volatile compounds were extracted from the different infected stages of Chinese white pine(Pinus armandi) needle,resin and phloem in Qinling forest ecosystem by steam distillation.Constituents of the volatile were identified by GC-MS.The major compounds were monoterpenoids,sequiterpenoids and diterpenoids,of which α-pinene,β-pinene,bomyl acetate,β-caryophyllene,α-caryophllene,α-cadinol,tau-cadinol,spathulenol,epi-bicyclosesquiphellandrene were dominant compounds.Moreover,the volatile constituents and contents were significant different at needles,resin and phloem of Chinese white pine,and the diversity of volatile constituents was obvious high than needle and resin.On the other hand,there were significant difference both in volatile compounds and constituents between healthy trees and infected trees.
