Analysis of Value-Added Resource Recovery of Wasted Branchlet and Nutshell of Camellia oleifera by GC/MS

The branchlet and nutshell of Camellia oleifera are produced in quantity while picking and processing the nut each year. However, the abundant branchlet and nutshell of C. oleifera are still underutilized and hence wasted to pollute environment. Therefore, GC/MS technology was used to analyze the top value-added components from the branchlet and nutshell of C. oleifera. After treated with freeze-drying, the branchlet was treated by benzene/ethanol extraction, and the nutshell was treated by direct pyrolysis in Helium atmosphere at 590 °C, respectively; then the extractives and pyrolyzate were analyzed by online linked GC/MS respectively. Relative content of each component was determined by area normalization. There are 45 components identified from 59 peaks in C. oleifera nutshell pyrolyzate, and there are 24 components identified from 27 peaks in the benzene/ethanol extractives of C. oleifera branchlet. The result by GC/MS analysis showed that the branchlet and nutshell of C. oleifera contain abundant components of rare medicinal materials and top value-added materials of high-grade cosmetic, bioenergy, and industrial chemical.
