目的:通过研究黄花香薷挥发油的化学成分,为黄花香薷的开发利用提供理论依据。方法:采用水蒸气蒸馏法提取黄花香薷挥发油,用GC毛细管柱进行分析,归一化法测其相对含量,并用气相色谱-质谱法对化学成分进行鉴定。结果:共鉴定出56个化合物,鉴定出的化合物含量占总挥发油的82.28%。主要成分为[1α,4aβ,8aα]-7-甲基-4-亚甲基-1-[1-甲基乙基]-1,2,3,4,4a,5,6,8a-八氢萘(相对含量为14.01%);[3S-[3α,5aα,7aα,11aα,11bα]]- 3,8,8,11a-四甲基-十二氢-5H-3,5a-环氧萘[2,1-c]氧杂环庚三烯(8.12%);2-甲基-3-亚甲基-环戊烷羧酸甲酯(7.30%);石竹烯(4.90%);α-杜松醇(4.11%);醋酸-[5α,16β]-D-雌甾-16-酯(3.96%);α-香柠檬烯(3.52%);吉玛烯B(3.08%);1,7-二甲基-1-羟基-4-异丙烯-2,7-环癸二烯(2.67%);α-石竹烯(2.20%);植醇(2.11%)。结论:本法简便、快速、灵敏度高。
Objective: To study the chemical constituents of the essential oil of Cinnamomum camphora and provide theoretical basis for its development and utilization. Methods: The volatile oil was extracted by steam distillation and analyzed by GC capillary column. The relative content was determined by the normalized method. The chemical constituents were identified by gas chromatography-mass spectrometry. Results: A total of 56 compounds were identified and the identified compounds accounted for 82.28% of the total volatile oil. The main component is [1α,4aβ,8aα]-7-methyl-4-methylene-1-[1-methylethyl]-1,2,3,4,4a,5,6,8a-octa Hydronaphthalene (relative content 14.01%); [3S-[3α,5aα,7aα,11aα,11bα]]- 3,8,8,11a-tetramethyl-dodecylhydro-5H-3,5a-epoxy Naphthalene[2,1-c]oxepine (8.12%); methyl 2-methyl-3-methylene-cyclopentanecarboxylate (7.30%); caryophyllene (4.90%); alpha - Jupasol (4.11%); acetic acid-[5[alpha],16[beta]]-D-estr-16-ester (3.96%); [alpha]-campolene (3.52%); gemene B (3.08%); 1, 7-dimethyl-1-hydroxy-4-isopropene-2,7-cyclodecadiene (2.67%); α-caryophyllene (2.20%); phytol (2.11%). Conclusion: This method is simple, rapid, and highly sensitive.
