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. ? 2018 Elsevier B.V.
