摘要：The chicken-wing wood belongs to "hongmu", which comes from the heartwood of three kinds of trees, M. leucantha, M. laurentii and C siamea. In this study, tri-step infrared spectroscopy macro-fingerprinting technique was employed to discriminate the three chicken-wing wood. Though three chicken-wing woods are extremely similar, some differences in chemical components emerged through Fourier Transition Infrared (FT-IR) spectra. Among them, M. leucantha and M. laurentii are cellulose-rich, while C siamea is lignin-rich. Besides, M. leucantha and C siamea have two peaks at 1328 and 782 cm(-1) belonging to calcium oxalate. An effective modeling approach to predict the content of cellulose was proposed. The result shows that cellulose content of M. leucantha, M. laurentii and C siamea were 45.84%, 40.92% and 38.85% respectively. According to Two-dimensional correlation infrared spectra (2DCOS-IR), number, position and intensity of auto-peaks in the range of 1250-1800 cm(-1) could be selected as the indicator to identify the three chicken-wing woods.
