目的:研究黄皮叶挥发油的化学成分。方法:采用水蒸汽蒸馏法从黄皮叶中提取挥发油,用毛细管气相色谱-质谱联用技术测定其化学成分和相对含量,用面积归一化法确定各成分的相对含量。结果:共鉴定了44个化学成分,占挥发油总量的91.81%。结论:主要成分为β-水芹烯(9.56%)、石竹烯(14.29%)(、S)-1-甲基-4-(5-甲基-1-亚甲基-4-己烯基)-环己烯(12.35%)、2,6-二甲基-6-(4-甲基-3-戊烯基)-二环[3.1.1]庚-2-烯(22.25%)等。
Objective: To study the chemical constituents of volatile oil from yellow leaf. Methods: Volatile oil was extracted from the leaves of Huangpi by steam distillation. The chemical composition and relative content were determined by capillary gas chromatography - mass spectrometry. The relative content of each component was determined by area normalization. Results: A total of 44 chemical constituents were identified, accounting for 91.81% of the total volatile oil. CONCLUSION: The main components are β-phellandrene (9.56%), caryophyllene (14.29%) (, S) -1-methyl-4- ) -cyclohexene (12.35%), 2,6-dimethyl-6- (4-methyl-3-pentenyl) -bicyclo [3.1.1] hept-2-ene .
