巴山冷杉树脂中挥发油化学成分的研究

A STUDY ON CHEMICAL CONSTITUENTS OF VOLATILE OIL IN THE RESIN FROM ABIES FARGESII

应用气相色谱和色谱—质谱—计算机联用法研究了巴山冷杉(Abies fargesiiFranch.)树脂中挥发油的化学成分。结果表明:(1)巴山冷杉挥发油的主要成分为柠檬烯α-蒎烯、坎烯、β-蒎烯、石竹烯、α-萜品烯、月桂烯和檀烯,含量占94.15—95.78%。(2)冷杉树脂在室温条件下密封贮存一年以后,其中挥发油的组成与新鲜样品基本相同,但含量不同。尤其是柠檬烯的含量由48.36%上升到55.27%,α—蒎烯的含量由31.86%下降到21.8%。

The volatile oil in the resin from Abies fargesii Franch.was analyzed by GC and GC/MS/DS techniques.The results showed: 1. that the main components of volatile oil are limonene, α-pinene, camphene, β-pinene, caryophyllene, α-terpinene, myrcene and santene, the contents of which amounted to 94.15-95.78% of the total oil. 2.That at room temperature, the resin can be kept in a sealed vial for more than one year without deterioration. The components of volatile oil in stored resin are comparable to fresh one with different contents of some components, especially, the limonene content which raised from 48.36% to 55.27%, and α-pinene content which dropped from 31.86% to 21.81%.
