GC/MS Determination of Bioactive Constituents of Benzene/ethanol Eztractive of Leaves of Two Eucalyptus Cultivars
In order to better utilize and recover the productive wastewater from the Eucalyptus oil and hence decrease its pollution to water environment, we used GC/MS to analyze the possible top value-added components of benzene/ethanol extractives of leaves of two Eucalyptus cultivars, i.e. E. camaldulensis and E. citriodora. Relative content of each component was determined by area normalization. 22 compounds representing 92.12％ of the benzene/ethanol extractive of E. camaldulensis leaves were identified, and the main constituents were 5-(acetylaminomethyl)-4-amino-2-methyl-(15.40％), hexadecanoic acid (10.25％), benzaldehyde,4-hydroxy-(8.64％), xylitol (7.57％), cyclopentanol (7.10％), 2-propenoic acid,3-(4-hydroxyphenyl)-(4.41％), eucalyptol (1.38％), etc. 28 compounds representing 98.41％ of the benzene/ethanol extractive of E. citriodora leaves were also identified, and the main constituents were ethanol,2-butoxy-(21.70％), benzene,methyl(1-methylethyl)-(15.61％), 17-octadecenal (15.25％), 1-hexacosanal (9.45％), 1-eicosanol (6.92％), cyclotetracosane (6.67％),.alpha.-phellandrene (3.75％), etc. The results of function analyses showed that the benzene/ethanol extractives of leaves of both E. camaldulensis and E. citriodora are abundant in materials of noble natural medicines, and also contains constituents which can be developed into top valueadded materials of cosmetic, biofuel and industrial solvent.
