Abstract:

To study the infrared spectrum application of animal’s hair on species classification. The Viverra zibetha and Viverricula indica straight guard hairs have been observed by FTIR (Fourier Transform Infrared Spectroscopy). The results showed the straight guard hair infrared spectrum had obvious difference from hair point to hair root, which indicated the same keratin that was controlled by identical gene existed in different part and the amount of keratin was different in different part. The FTIR of Viverra zibetha and Viverricula indica straight guard hairs middle part had distinct interspecific difference for the peak area and strong peak’s point of The Viverra zibetha and Viverricula indica straight guard hairs’ FTIR were clearly different in the range of 626-655 cm. The stretching vibration M-shaped adsorption peak of N-H group at 640.3 cm and 646.1 cm showed that isomerism keratin existed in the Viverra zibetha. FTIR analysis hold better applied foreground in the detection and analysis of animal hairs and it could be provided for wildlife taxonomy and identification.
