Identification of Chemical Components of Waste Leaves from Cinnamomum camphora by Py-GC/MS

摘要

In order to better utilize and recover the productive waste leaves from the Cinnamomum camphora,pyrolysis-GC/MS technology was used to analyze the possible top value-added components of benzene/ethanol extractives of Cinnamomum canphora leaves.Relative content of each component was determined by area normalization.95 compounds from 102 peaks representing 99.216％ of the benzene/ethanol extractives of Cinnamomum camphora leaves were identified,and the main constituents were Hexadecanoic acid,4-nitrophenyl ester (17.336％),Vitamin E (4.804％),Oxirane,hexadecyl-(4.639％),2,6-Bis(3,4-methylenedioxyphenyl)-3,7-dioxabicyclo(3.3.0)octane (4.333％),1-Hexacosene (4.148％),Hexadecanoic acid,2-methoxy-,methyl ester (3.783％),1,19-Eicosadiene (3.607％),3-Cyclohexene-1-methanol,.alpha.,.alpha.4-trimethyl-(3.542％),.gamma.-Sitosterol (3.495％),Nonacosane (3.217％),.gamma.-Tocopherol (3.119％),Eucalyptol (2.23％),vanillin (2.742％),Heptacosane (2.182％),Pentatriacontane (2.039％),1-Nonadecene (2.011％),etc.The results of function analyses showed that the 350 °C pyrolyzate from benzene/ethanol extractives of waste leaves of Cinnamomum camphora are abundant in materials of noble natural medicines and cosmetic.
