Determination of Bioactive Components in 300°C Pyrolyzate of Extract from Oil-Tea Cake by Pyrolysis- GC/MS

The oil-tea cake as the byproduct of tea-oil from oil-tea seed is still not top-valued used. In order to improve the processing status of oil-tea cake from low-grade to high-grade, we used 300°C pyrolysis- GC/MS technology to analyze the top value-added biomedical and bioactive constituents of two extracts (benzene/ethanol and acetone) of oil-tea cake. Relative content of each component was determined by area normalization. 13 compounds representing 99.18% of the benzene/ethanol extract of oil-tea cake were identified, and 28 compounds representing 98.62% of the acetone extract of oil-tea cake were also identified, The results of function analyses showed that the benzene/ethanol extract and acetone extract of oil-tea cake contain abundant components of rare natural medicinal materials, and also contain many components which can be developed into two value-added materials of high-grade spice, cosmetic, food, and industrial chemical and solvent, This result will benefit the status change of processing and utilization of oil-tea cake in China from low-grade to high-grade, and hence is helpful to the sustainable development of oil-tea industry of China.
