Abstract: The extractives of C. camphora old bark were used to cure some special diseases; however, the biomedical constituents of extractives of C. camphora old bark are still not completely explained. Therefore, 350 °C-based pyrolysis- GC/MS technology was used to identify the top value-added biomedical constituents of old bark-based benzene/ethanol extractives from C. camphora trunk. 74 chemical constituents representing 99.17% were identified from 86 peaks. The main components are as: Dodecanoic acid, 1-(hydroxymethyl)-1,2-ethanediyl ester (15.717%), Octacosanoic acid, methyl ester (10.357%), Abietic acid (8.483%), Heptacosane (5.678%), Ethyl alcohol (5.282%), Hexadecanoic acid, 2-hydroxy-, methyl ester (3.365%), Hexacosanoic acid, methyl ester (2.936%), 1,2-Benzenedicarboxylic acid, butyl 2-methylpropyl ester (2.928%), 2-Methoxy-4-vinylphenol (2.692%), Hexadecanoic acid, ethyl ester (2.312%), Hexacosane (2.076%), Tetracosanoic acid, methyl ester (2.013%), etc. The analytical result showed that the 350 °C pyrolyzate of benzene/ethanol extractives from C. camphora old bark is abundant in biomedical constituents, and also contains other bioactive components, which can be used as top value-added materials of high-grade cosmetic, food, spice and chemical solvents.
