Py-GC/MS Analysis on Bio-Energy Sources of Acetic Ether Extractives of Eucalyptus camaldulensis Wood
The high-grade resource recovery on acetic ether extractives in E. camaldulensis wood was analyzed by means of Py-GC/MS, and relative content of each component was determined by area normalization. Results showed that main constituents of acetic ether extractives were ergosta-4,6, 22-trien-3.beta.-ol (12.53%), 1-phenanthrenecarboxylic acid, 1,2,3,4,4a,9,10,10a-octahydro -1,4a-dimethyl-7-(1- methylethyl)-, methyl ester (10.87%),oleic acid (10.65%), etc. So it can be concluded that rare medicinal materials and spice are not only abundant in acetic ether/acetone extractives, but also its by-products can be used as top-grade cosmetics, bioenergy etc.
