The Comparation of Chemical Component Analysis about Volatile Oil from Cinnamomum Cassia Bark,Cinnamomum Cassia Presl and Cinnamomum Cassia Leaf by Gas Chromatography-Mass Spectrometry

The volatile oil was extracted from Cinnamomum cassia bark,Cinnamomum cassia presl and Cinnamomum cassia leaf by steam distillation.Volatile components of Cinnamomum cassia oils was analyzed by using gas chromatography-mass spectrometry,the relative content of these compounds were calculated using square peaks to normalization.The main chemical component of volatile oil was similar in three sections.The result shows that the yield of Cinnamomum cassia bark is tiptop,Cinnamomum cassia presl takes the second place,Cinnamomum cassia leaf is the lowest.36 components were identified in the oils.The chemical component of Cinnamomum cassia bark was(E)-Cinnamaldehyde(60.42 %),(E)-2-Propenal,3-(2-methoxyphenyl)-(18.81 %) Cinnamic acid(8.86 %) and so on;The chemical component of Cinnamomum cassia presl oil was(E)-Cinnamaldehyde(47.38%),(E)-2-Propenal,3-(2-methoxyphenyl)-(23.21%),Cinnamic acid(7.65 %) and so on;The volatile oil of Cinnamomum cassia leaf was(E)-Cinnamaldehyde(38.27 %),(E)-2-Propenal,3-(2-methoxyphenyl)-(29.36 %),Coumarin(7.18 %) and so on,and it was quite complex.
