目的:研究柳蒿芽挥发油的提取方法并分析其主要成分。方法:采用超临界CO2流体萃取法、水蒸气蒸馏法提取柳蒿芽挥发油并比较收率。采用GC-MS法分析柳蒿芽挥发油的组成成分。结果:超临界CO2流体萃取法提取柳蒿芽挥发油的收率为0.197%,鉴定38个化合物;水蒸气蒸馏法提取柳蒿芽挥发油的收率为0.183%,鉴定38个化合物,两种方法提取柳蒿芽挥发油共有成分有14个。结论:柳蒿芽挥发油超临界CO2流体萃取法收率高于水蒸气蒸馏法。柳蒿芽挥发油提取方法不同,其成分不完全相同。柳蒿芽挥发油的主要成分为:1,8-桉叶素、马鞭草烯醇、α-姜黄烯、α-石竹烯等。
Objective: To study the extraction method of volatile oil from Artemisia selenges and analyze its main components. Methods: The supercritical CO2 fluid extraction and steam distillation were used to extract the essential oil of Artemisia mandshurica and compare the yield. GC-MS method was used to analyze the composition of the essential oil of Artemisia selenges. Results: The extraction yield of volatile oil from Artemisia selengensis was 0.197% by supercritical CO2 fluid extraction, and 38 compounds were identified. The yield of volatile oil from Artemisia selengensis was 0.183% by steam distillation, 38 compounds were identified and extracted by two methods Artemisia buds volatile oil has a total of 14 ingredients. Conclusion: The yield of volatile oil from Artemisia selengensis L. by supercritical CO2 fluid extraction is higher than that of steam distillation. Artemisia buds volatile oil extraction methods are different, its composition is not exactly the same. The main components of Artemisia annua volatile oil: 1,8-cineole, verbena enol, α-curcumin, α-caryophyllene and so on.
