CHEMICAL COMPOSITIONS AND FUNCTIONS OF CAMPHOR TREE VOLATILES

Abstract

Camphor tree is the dominant tree species of evergreen broad - leaved forest in subtropical regions of China, and has important ecological and economic effects. A large number of scholars have studied the camphor extract. In this paper, the camphor tree powder volatiles were analyzed by fourier transform infrared spectroscopy (FT-IR), thermogravimetry (TG), pyrolisis-gas chromatography-mass spectrometry (Py-GC-MS), thermal desorption-gas chromatography-mass spectrometry (TD-GC-MS). Experiments show that camphor volatile composition contains alcohols, phenol, ester, aromatic, amine. Camphor tree powder was detected in PY-GC-MS analysis, 50 peaks were detected and 12 chemical constituents were identified and the peak area accounted for 20.78% of the total peak area. Camphor tree powder was detected in TDS-GC-MS analysis, 9 chemical constituents were identified in 34 peaks.
