摘 要：
试验分别采用超临界CO2流体萃取和水蒸汽蒸馏技术提取依兰香花挥发油,超临界CO2流体萃取技术挥发油提取率为3.9%,明显高于水蒸汽蒸馏技术挥发油得率3.0%。采用GC-MS方法对挥发油成分进行分析,两种提取技术所得挥发油组成成分基本一致,确定出依兰香花挥发油成分有β-石竹烯、Germacrene D、苯甲酸苄酯、1,4,7,-Cycloundecatriene,1,5,9,9-tetramethyl-,Z,Z,Z-、以及乙酸薰衣草酯等近20种。试验表明,超临界CO2流体萃取更适用于依兰香花挥发油的提取,并且β-石竹烯可以作为衡量依兰香花挥发油品质的重要参考。

摘 要：
Supercritical CO2 fluid extraction and steam distillation techniques were applied on the volatile oil extraction of Cananga odorata flower, individually,the yield rate of volatile oil from supercritical CO2 fluid extraction is 3.9 %, much higher than that of steam distillation techniques. GC-MS was adopted to analysis the constitutes of the volatile oil, the components of volatile oil from the two extraction methods are identical basically, nearly twenty kinds of constitutes were identified, including β-caryophyllene, Germacrene D, Benzoic acid benzyl ester, 1,4,7,-Cycloundecatriene,1,5,9,9-tetramethyl-,Z,Z,Z-, and Lavender ester of acetic acid et al.. By comparision, Supercritical CO2 fluid technique is more suitable to the volatile oil extraction of Cananga odorata flower, and β-caryophyllene can serve as an important reference to measure quality of the volatile oil.
