GC/MS Analysis of Bioactive Components of Benzene/Ethanol Extractive and Pyrolyzate from Wasted Kernel Hull of Camellia Oleifera Seed

The kernel hull of Camellia oleifera seed is underutilized and still wasted, therefore, we used GC/MS to analyze the top value-added bioactive components of benzene/ethanol extractive and pyrolyzate from the kernel hull of C. oleifera seed. After treated with freeze-drying, the fresh kernel hull was treated by benzene/ethanol extraction and direct pyrolysis in Helium atmosphere at 590 degC, respectively, then the extractive and pyrolyzate were analyzed by online linked GC/MS respectively. Relative content of each component was determined by area normalization. There are 15 components identified in the benzene/ethanol extractive, and the main constituents are 2- furancarboxaldehyde,5-(hydroxymethyl)- (32.37%), 1,3- propanediol,2-ethyl-2-(hydroxymethyl)- (28.34%), 1,2,3- benzenetriol (15.10%), 4H-pyran-4-one,2,3-dihydro-3,5- dihydroxy-6-methyl- (5.39%), 2-furancarboxaldehyde (3.68%), etc. However, 38 compounds were identified from kernel hull pyrolyzate, and the main constituents are ethyne,fluoro- (21.95%), acetic acid (23.53%), butane (11.85%), acetaldehyde,hydroxy- (5.63%), 2-propanone, l-hydroxy- (5.59%), heptadecane, 9-octyl- (4.00%), etc. the analytical result by GC/MS showed that both the benzene/ethanol extractive and pyrolyzate of kernel hull of C. oleifera seed contain abundant components of rare natural medicinal materials, and also contain components which can be developed into two value-added materials of high-grade cosmetic, bioenergy, and industrial chemical and solvent.
