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 camphora 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.
