Abstract: This study aimed to verify the availability of fossil cellulose by extracting ��-cellulose from the Miocene mummified fossil woods from Xianfeng of Yunnan. In this experiment, five samples in the studied area were first processed by organic solvent separation, alkaline solution separation and inorganic acid separation, and then compared with modern wood ��-cellulose and international standard ��-cellulose with the help of infrared spectrum detection technique. As a result, it showed that all these three extraction methods could extract ��-cellulose from fossil woods, but the individual characteristics were different. Among them, the organic solvent separation experiment process took the longest time, and the alkaline solution separation had the largest sample loss. Whereas the inorganic acid separation method was the most efficientonefor ��-celluloseextractionfrommummifiedfossil woods.
