Abstract—The oil-tea cake as the byproduct of tea-oil from oil-tea As the byproduct, oil-tea cake (dreg cake of tea-oil tree
seed is still not top-valued used. In order to improve the seeds) has specific use prehensive utilization. Besides
processing status of oil-tea cake from low-grade to high-grade, we the considerable residual oil, oil-tea cake also contains
used 300°C pyrolysis- GC/MS technology to analyze the top abundant tea saponin, crude fiber, amyloses and proteins [4].
value-added biomedical and bioactive constituents of two extracts Especially, oil-tea cake is widely used to extract tea saponin,
(benzene/ethanol and acetone) of oil-tea cake. Relative content of distill the residual oil, and produce polishing powder. This
ponent was determined by area normalization. 13 increases the economic benefit prehensive utilization of
co
