terpinene

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.

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%。

The principal constituents of the volatile oil were β pinene ( 36 536%),α pinene,Δ 3 carene,γ terpinene, bornyl acetate, terpinyl acetate, longifolene etc. The total content of the above 33 compounds is 99 79% of the volatile oil.

其中含有α-蒎烯、Δ3-蒈烯、γ-松油烯、乙酸龙脑酯、乙酸萜品酯及长叶烯等，含量最多的成分是β-蒎烯（36.536%）。

Mordenite-catalyzed isomerization of α-pinene resulted in thirteen products including camphene, limonene, terpinolene, α-terpinene, γ-terpinene, tricyclene and β-fenchene etc.
