Abstract: In order to obtain the extraction technology and the correlation properties of volatile oil from cinnamon peel with accelerated solvent extraction,the conditions of extraction are investigated using Box-Behnken experimental design.The effects of extraction time,temperature,and extraction times are respectively studied in the study.The parameters of samples such as chemical composition, refractive index, acid value, etc. are measured with gas chromatography-mass spectrometry (GC-MS).The results show that the optimum technological conditions of samples are as follows:the extraction time of 327 s,the temperature of 92 ℃,the extraction times of 2,the predicted extraction yield is 1.168%and the observed extraction yield is 1.133%,which is 0.035%less than the predicted value.A total of 48 components are identified from the essential oils with trans-cinnamaldehyde (34.11%),cis-cinnamic aldehyde(4.18%),cinnamic acid(19.96%),α-pinene(3.90%),α-ionene (2.64%),2-methoxycinnamaldehyde (1.43%),α-ylangene (2.45%),α-cadinol (1.27%),guaiene (1 .79%)among them by the area normalization method.The volatile oil obtained has the characteristic aroma of cinnamon and pale yellow performance,the refractive index is measured of 1.6094,and the acid value is 4 .5 .
