Py-GC/MS Analysis of Bioactive Components of 450°C Pyrolyzate from Ethanol Extractives of Oil-Tea Cake
450°C-based pyrolysis- GC/MS technology was used to analyze the bioactive components of ethanol extractives of oil-tea cake. The analytical result showed that 38 peaks were obtained from the 450°C-based pyrolyzate of ethanol extractives of oil-tea cake, and 37 compounds representing 97.81 % of the total areas were identified (Table 1). The analytical result showed that the main components of ethanol extractives of oil-tea cake by 450°C-based pyrolysis- GC/MS were as: Benzene, 1,2,3-Trimethoxy-5-Methyl- (21.56%), Phenol, 3,4-Dimethoxy- (16.31%), 3',5'-Dimethoxyacetophenone (14.37%), 1,2-Ethanediamine, N-Ethyl- (6.62%), Indole (5.39%), Mequinol (4.13%), Phosphonic Acid, (P-Hydroxyphenyl)- (2.97%), 1,2-Cyclobutanedicarboxylic Acid, Cis- (1.67%), Bicyclo 3.1.0 Hexan-3-One (1.38%), Benzene, 1,4-Dimethoxy-2,3,5,6- Tetramethyl- (1.35%), 2h-Azepin-2-One, Hexahydro-1-(2-Propenyl)- (1.15), etc. The results of function analyses showed that the 450°C-based pyrolyzate of ethanol extractives of oil-tea cake can be used as rare natural medicinal materials, and value-added materials of spice, food and cosmetic industry.
