采用水蒸气提取的方法,对浸泡后的桂叶进行加热处理,破坏桂叶的细胞组织使其精油得以释放,以水蒸气辅助提取,再经过冷却、离心得到肉桂精油.通过单因素实验以及正交实验,得到最佳提取工艺条件:浸泡5 h、提取功率900 W、提取时间3 h.其中提取功率对提取率的影响最大.肉桂叶的精油提取率最高可达到7.13‰.最后采用气质联用仪(GC-MS)对提取的肉桂精油和化学合成的肉桂醛产品进行成分分析,发现提取的精油中主要成分为反式肉桂醛、邻苯二甲酸二乙酯、丁香酚,化学合成的产品主要成分为反式肉桂醛和肉桂酸.根据二者成分的差异迅速区分天然提取和化学合成的产品.
The method of steam extracting is used to heat the leaves of
cinnamon
soaked by water
which can break the cells of
cinnamon
leaves to release essential oil. Then water is added to the reaction for assistant extracting
followed by centrifuging and cooling down to obtain
cinnamon
oil. Single factor experiment and orthogonal test show the highest essential oil extraction rate of
cinnamon
leaves can reach 7.13‰ under the extracting conditions: soaking for 5 hours and 900 W of extracting power
extraction time of 3 hours. Especially
the power has significant influence on
cinnamon
oil extracting. Finally
the composition of extracted
cinnamon
oil is analyzed by GC-MS
(Gas Chromatograph-Ma
ss Spectrometer-computer
GC-MS).The result shows that the main compositions of extracted essential oil are trans-Cinnamaldehyde
Diethyl phthalate and Eugenol
while the main components of chemical synthesis products are trans-Cinnamaldehyde and cinnamic acid. The two products can be distinguished quickly through the different components.
