TITLE:
摘要: 目的:比较2种不同方法提取艾叶挥发油的效果。方法:以挥发油得率和挥发油中桉油精含量为考察指标,以不同产地的艾叶(河南汤阴、安徽霍山、湖北蕲春,采集日期均为5-6月)及不同采集日期(5、6、7、8月)的湖北蕲春艾叶为对象,比较水蒸气蒸馏法和超临界CO2萃取法提取艾叶挥发油的效果。结果:在水蒸气蒸馏法和超临界CO2萃取法中以后者提取的挥发油得率较高,但桉油精含量结果相近;各样品中,2种方法下均以湖北蕲春6月采集的艾叶挥发油得率(0.585%、2.42%)和桉油精含量最高(0.591、0.548 mg/g)。结论:建议选择上述2种方法提取中药材的挥发油时,应综合考虑挥发油得率、有效成分含量及相应的提取操作和工业成本等因素选择适合的提取方法。
ABSTRACT: OBJECTIVE: To compare the effects of two extraction methods of volatile oil from A. argyi. METHODS: With the yield rate of volatile oil and the content of eucalyptol in the volatile oil as the observed indexes, using the A. argyi grown in different places (Tangyin, Henan; Huoshan, Anhui; Qichun, Hubei; picked during May and June) and the A. argyi picked on different dates (in May, June, July and August) in Qichun, Hubei. Steam distillation and supercritical CO2 extraction method were compared with respect to the effect of extraction of volatile oil from A. argyi. RESULTS: Compared to steam distillation, the yield rate of volatile oil obtained by supercritical CO2 extraction method was higher, but the contents of eucalyptol obtained by the two methods were similar. Among all samples processed by the two methods, the A. argyi picked in Qichun, Hubei in June had the highest yield rates of volatile oil (0.585% and 2.42%) and contents of eucalyptol (0.591 and 0.548 mg/g). CONCLUSIONS: It is suggested that the yield rate, the content of active ingredient, corresponding extraction procedures, industrial cost and other factors should be considered when choosing a more suitable extraction method from the two methods mentioned above to extract the volatile oil from traditional Chinese medicinal materials.
