目的:分析橘叶挥发油的化学成分。方法:采用水蒸汽蒸馏法提取橘叶挥发油,用气相色谱-质谱(GC/MS)联用法分析鉴定其化学成分,并应用面积归一法测定各成分的相对百分含量。结果:从橘叶挥发油中分离出50种化学组分,鉴定了其中34种,占总油量的83%。结论:橘叶挥发油中主要成分为β-榄香烯(19.96%)、石竹烯(10.27%)、石竹烯氧化物(8.78%)、[1R-(1a,3aβ,4a,7β)]-1,2,3,3a,4,5,6,7-八氢-1,4-二甲基-7-(1-甲基乙烯基)-薁(6.97%)、邻伞花烃(6.27%)等。
Objective: To analyze the chemical constituents of the volatile oil of orange leaves. Methods: Volatile oil of orange leaves was extracted by steam distillation. The chemical constituents were identified by gas chromatography - mass spectrometry (GC / MS). The relative percentages of the constituents were determined by area normalization. Results: Fifty chemical constituents were isolated from the volatile oil of orange leaves and 34 of them were identified, accounting for 83% of the total oil content. CONCLUSION: The main constituents of the volatile oil of orange leaves are β-elemene (19.96%), caryophyllene (10.27%) and caryophyllene oxide (8.78%), [1R- (1a, 3aβ, 4a, 7β) , 2,3,3a, 4,5,6,7-octahydro-1,4-dimethyl-7- (1-methylvinyl) -stilbene (6.97%), paraquat (6.27% )Wait.
