目的:对不同提取方法所得的白术挥发油成分进行比较研究.找出一种更利于白术挥发油提取的方法.方法:采用GC-MS对水蒸气蒸馏法、超声波溶剂提取法和超临界CO_2萃取法所得白术挥发油成分进行分析.结果:水蒸气蒸馏法挥发油得率为1.01%,共有18个峰鉴定15个;超声波提取法得率为1.60%,分离得24个峰鉴定20个;超临界CO_2萃取法挥发油得率为2.32%,共得49个峰鉴定37个.挥发油中以苍术酮(Atractylon)含量最高,3种方法所得挥发油的已鉴定峰中有12个共有成分.结论:3种不同提取方法所得的白术挥发油成分存在差异但也有共同特征,超临界CO2萃取法提取白术挥发油得率更高,成分更加全面.

OBJECTIVE: To study on volatice oil from Atractylodes macrosephala Koidz with different distill methods and find the better method. METHODS: GC-MS was used to analyze the chemical constituents of volatice oil from Atractylodes macrocephala Koidz with different distill methods. RESULTS: The extraction rates of volatice oil with steam distillation was 1.01%, the components of the oil were examined by GC-MS, 15 of the 18 were identified. The extraction rates of volatice oil with ultrasonic wave was 1.60%, the components examined, 20 of the 24 were identified. The extraction rates of volatice oil ...
