ZHOU Guang-lai1,DAN You-meng2,WAN Zuo-xi1,YU Zhan-shen1,LIU Jun3(1.School of Biological Science and Technology,Hubei University for Nationalities,Enshi 445000,China;2.School of Chemistry and Environmental Engineering,Hubei University for Nationalities,Enshi 445000,China;3.College of Life Science and Technology,Huazhong Agricultural University,Wuhan 430070,China)  
In the paper,various kinds of Amorphophallus are identified through thermo analysis.The TG-DTG curves Amorphaphollus konjac,Amorphaphollus albus and Amorphaphollus hong are investigated by TG-DTG technique in the static air atmosphere.The study shows that different kind of Amorphophallus will be carbonized when the temperature is over 272.8℃、270.8℃ and 265.1℃,and it will be burned when the temperature over is 469℃、476.3℃ and 433.5℃ in the DTG curves.By comparing the characters of DTG curves of samples,the different kind of Amorphophallus is found to have obvious difference.The various kind of Amorphophallus is easy to distinguished according to the peak position of thermo decompose in the DTG curves.
