Identification of Chemical Components of Waste Leaves from Cinnamomum camphora by Py-GC/MS
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 ℃ pyrolyzate from benzene/ethanol extractives of waste leaves of Cinnamomum camphora are abundant in materials of noble natural medicines and cosmetic.
