Abstract: To explore the effects of different treatments on the surface chemical performance, components of Phgllochys heterocycla var.pubscensewere studied in this paper.The carbon to oxygen ratio(C/O ratio), distribution of C_1s infour combining forms, and the position and relative absorbing intensity of peaks of Fourier TransformationInfrared Spectroscopy(FTIR) were analyzed by Electron Spectroscopy for Chemical Analysis(ESCA) and FTIRunder various positions and processing conditions of the bamboo surface.Results showed that:there were significant differences in the carbon to oxygen ratio(C/Oratio) among various positions and processing conditions;lignin and abstracts mainly made up the surface of bamboo;high temperature drying resulted in the decomposition of volatile abstracts in the surface, which indicated some structure of cellulose and hemicellulose, while the effects of processing with boracic acid were not apparent;the bamboo processed in high temperature and with boracic acid showed decreased free hydroxide and activity at the same time;the amount of active free hydroxide of inner layer was higher than that of the outer.
