摘要: 采用气相色谱-质谱联用技术对水蒸气蒸馏法(SD)和超声辅助提取法(UAE)提取的华细辛挥发油化学成分分离分析。结果表明:鉴定出的24种化合物,主要有甲基丁香酚、3,5-二甲氧基甲苯、黄樟醚、十五烷、卡枯醇、3,4-(亚甲基二氧)苯丙酮、优葛缕酮、龙脑、2,4-二甲氧基-3-甲基苯丙酮、N-异丁基十二碳四烯酰胺、芝麻素。两种方法提取的挥发油成分相同,但是超声辅助提取法所得部分成分质量分数比水蒸气蒸馏法提取的高1.2~24倍,其中芝麻素和6-十八烯酸的质量分数分别相差24及21倍,表明超声辅助提取法对华细辛挥发油中热不稳定和非挥发性化合物有更好的提取效果。

Abstract: In this paper, steam distillation (SD) and ultrasound-assisted extraction (UAE) methods were separately coupled to gas chromatography-mass spectrometry (GC-MS) to the chemical composition of volatile oil from Asarum sieboldii Miq. As a result, 24 compounds including methyleugenol, 3,5-dimethoxytoluene, safrole, pentadecane, kakuol, 3',4'-(methylenedioxy)propiophenone, eucarvone, borneol, 2',4'-dimethoxy-3'-methylpropiophenone, N-isobutyldodecatetraenamide and sesamin were identified. However, UAE revealed a 1.2-24-fold increase in partial components in comparison with SD. The contents of sesamin and 6-octadecenoic acid obtained by UAE were 24 and 21 times larger than that by steam distillation method, respectively. These studies suggested that UAE is superior to SD for both thermally unstable and non-volatile compounds in volatile oil from Asarum sieboldii Miq..
