| Abstract: | Objective] GC-MS was conducted on chemical constituents of volatile oil from Sinopodophyllum emodi.Method] Chemical constituents of volatile oil from Sinopodophyllum emodi was extracted by Ultrasonic and Soxhlet method,and the constituents were analyzed by GC-MS and computer database,and the structure identification of isolated components was conducted with database NIST2008 of mass spectrometry.The relative content of each component was calculated by area normalization.Result] Among 48 compounds,the matching degree of 32 compounds is higher with mass spectrometry database,accounting for 66.66% of volatile components.There are 5 kinds of amine accounting for 1.16%,6 kinds of acid,accounting for 6.04%,5 kinds of alcohols accounting for 6.55%,9 kinds of ester,accounting for 38.82%,4 kinds of ketone accounting for 10.09%.Conclusion] The identification of chemical compounds which extracted by Ultrasonic and Soxhlet extraction is helpful for finding out characteristic compounds from volatile oil of Sinopodophyllum emodi.The methods can be applied in specialized isolation and identification of other samples. |
