Chemical components analysis of Toona sinensis bark and wood by pyrolisis-gas chromatography-mass spectrometry

The production of energy from wood biomass is as old as humanity itself. There has been enormous progress in research of sustainable pyrolysis processes for optimal energy conversion in the past 30 years. Pyrolisis-gas chromatography-mass spectrometry (PY-GC-MS) was used to examine the components of bark and wood of Toona sinensis for expanding high value utilization different parts of trees. In the study, 174 chemical constituents were identified in the bark; 169 chemical constituents were identified in the wood, respectively. The chemical composition of bark is different from that of wood. The change in thermal cracking 30 min ago is not very large. In the retention time is more than 30 min, they are very different. Because the ash content of bark had much large corresponding wood. Mainly the phenols and their derivatives formed after the pyrolysis of lignin and extractives. The chemical composition of T. sinensis provides a scientific basis for the development and utilization of the plant. The richer chemical constituents of T. sinensis are found, which will provide new scientific evidence for further development and utilization of bark and wood of T. sinensis.
