Py-GC/MS Analysis on Biomedicine of Ether/acetone Extractives from Eucalyptus camaldulensis Biomass

摘要

Eucalyptus camaldulensis biomass has been widely used in fiber and pulp. However, this would result in serious water pollution and meanwhile bring a great waste of biological resources. Therefore, the ether/acetone extractives of Eucalyptus camaldulensis biomass were identified by Py-GC/MS. The main 350°C pyrolysis components were 7-Oxabicyclo[3.3.1]non-2-ene,8-(4-methoxyphenyl)-2,4,9-trimethyl-(7.1%), Indolo[2,3-b]quinoxaline, l-fluoro(4.23%), etc.The main 550°C pyrolysis components were 7-Oxabicyclo[3.3.1]non-2-ene,8-(4-methoxyphenyl)-2,4,9-trimethyl-(7.1%), Indolo[2,3-b]quinoxaline, l-fluoro(4.23%), etc. And the main 750°C pyrolysis components were oleic acid(6.77%), 10,18-bisnorabieta-5,7,9(10),11,13-pentaene(2.33%), 9,12-hexadecadienoic acid, methyl ester(2.12%), etc. So the ether/acetone extractives of Eucalyptus camaldulensis could be used as biomedicine.
