Pyrolysis-GC/MS of Bioactive Components of Acetone Extractives of Oil-Tea Cake under 300°C
The current processing and utilization of oil-tea cake is still characterized by low economic benefit and low value added, therefore, 300°C-based pyrolysis- GC/MS technology was used to analyze the bioactive components of acetone extractives of oil-tea cake. Relative content of each component was determined by area normalization. The analytical result showed that the main components from 300°C-based pyrolyzate of acetone extractives of oil-tea cake by pyrolysis- GC/MS were as: SQUALENE (18.61%), 9-OCTADECENAL, (Z)- (15.27%), 3',5'-DIMETHOXYACETOPHENONE (9.53%), HEXADECANOIC ACID (7.28%), (Z)14-TRICOSENYL FORMATE (5.15%), .GAMMA.-SITOSTEROL (3.82%), BIS(2-METHOXYETHYL) PHTHALATE (2.86%), ERGOST-5-EN-3-OL, (3.BETA.)- (2.31%), etc. The results of function analyses showed that the 300°C-based pyrolyzate of acetone extractives of oil-tea cake contain rich components of rare natural medicinal materials, and also contain value-added materials of high-grade spice, food, cosmetic and bioenergy.
