GC/MS Analysis of Bioactive Components of Benzene/ethanol Eztractive 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℃, 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,1-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.
