Abstract :
The fruit hull and kernel hull of Camellia oleifera are still underutilized and hence abandoned to pollute environment. Therefore, Pyrolysis- GC/MS was used to analyze the top value- added biomedical components from the fruit hull and kernel hull of C. oleifera fruit. After treated with freeze-drying, the fresh fruit hull and kernel hull were pyrolyzed in Helium atmosphere at 590degC respectively, then the two pyrolyzates were analyzed by online linked GC/MS. Relative content of each component was determined by area normalization. 48 compounds representing 98.29 % of fruit hull pyrolyzate were identified from 61 peaks, and the main constituents are acetic acid (18.79%), 2- propanone,1-(1-methylethoxy)- (8.88%), acetic acid, methyl ester (9.12%), 2-propanone,l-hydroxy- (5.39%), 2- furancarboxaldehyde (5.37%), cyclobutanol (3.01%), etc. 38 compounds representing 97.28 % of kernel hull pyrolyzate were identified from 47 peaks, and the main constituents are ethyne,fluoro- (21.95%), acetic acid (23.53%), butane (11.85%), acetaldehyde,hydroxy- (5.63%), 2-propanone,1-hydroxy- (5.59%), heptadecane,9-octyl- (4.00%), propane (3.54%), nonacosane (3.39%), heptadecane (2.62%), etc. As the first report here, the Pyrolysis- GC/MS result showed that the pyrolyzates of fruit hull and kernel hull of C. oleifera contain abundant components of rare medicinal materials and byproducts which can be developed into two value-added materials of high-grade cosmetic, bioenergy, and industrial chemical and solvent.
