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.

450°C-Based Pyrolysis- GC/MS Analysis of Utilization of Benzene/Ethanol-Extracted Residue from Oil-Tea Cake

The extractives of oil-tea cake are considered to have bioactive components, but the extracted residues of oil-tea cake are still not utilized. The analytical result by 450°C-based Pyrolysis-GC/MS showed that 42 peaks were obtained from the 450°C pyrolyzate of benzene/ethanol-extracted residues of oil-tea cake, and 41 compounds representing 97.53% of the total areas were identified. The analytical result revealed that the main components of benzene/ethanol-extracted residues of oil-tea cake by 450°C-based pyrolysis- GC/MS were as: Ethanone, 1-(2-Hydroxy-5-Methylphenyl)- (19.16%), Phenol, 2-Methoxy-6-(2-Propenyl)- (15.24%), Mequinol (14.37%), 2-Cyclohexen-1-One, 4,4,6-Trimethyl- (6.51%), 1,2-Cyclobutanedicarboxylic Acid, Trans- (5.68%), 3-Tert-Butyl-4-Hydroxyanisole (4.92%), Phenol, 2-Methoxy-4-Methyl- (4.33%), Phenol, 4-Ethyl-2-Methoxy- (3.62%), Vanillin (3.59%), Phenol, 2,6-Dimethoxy-4- (2-Propenyl)- (3.17%), N,N-Dimethyl-2-Cyclohexyloxyethylamine (2.94%), 1,3-Cyclopentanedione, 2-Methyl- (2.85%), Eugenol (2.56%), etc. The results of function analyses showed that the benzene/ethanol-extracted residues of oil-tea cake contain abundant components of rare natural medicinal materials, and materials of high-grade spice, cosmetic and food industry.
