GC/MS Analysis on Biomedical Resources of Extractives of Eucalyptus Leaves for Biomedical Engineering
To further utilize Eucalyptus leaves in biomedicine and put forward new ideas for biomedical manufacturing, the biomedical resources of extractives of Eucalyptus camaldulensis and Eucalyptus urophylla leaves were analyzed by GC/MS. The results showed that: 1) The main constituents of benzene/ethanol extractives in E. camaldulensis leaves were 1-butanol, 4-butoxy- (14.97%), 2-furancarboxaldehyde, 5-(hydroxym ethyl)- (12.16%), 1,2,3-benzenetriol (10.97%), d-allose(8.59%), 1,4,7,10,13,16-hexaoxanonadecane, 18-propyl-(6.82%), 1,1'-biphenyl, 2,4'- dimethyl- (6.21%), 1-benzoxiren-3-ol(5.58%), α-tocopherol-β-d-mannoside(3.77%), benzene, 1-methyl-2-(phenylmethyl)- (3.61%), methyl β-d-galactopyranoside(3.41%), etc. 2) The main constituents of benzene/ethanol extractives in E. urophylla leaves were 1,2,3-benzenetriol(15.22%), 1,4,7,10,13,16-hexaoxanonadecane, 18-propyl-(8.66%), 3,6,9,12-tetraoxatetradecan-1-ol, 14-[4- (1,1,3,3-tetramethylbutyl)phenoxy]-( 5.79%), naphthalene, 1,2,4a,5,8,8a-hexahyd ro-4,7-dimethyl-1 -(1-methylethyl)- (4.93%), 1,2,3-butanetriol(3.61%), ethyl α-d-glucopyranoside(3.29%), 2-furancarboxaldehyde, 5-(hydroxym ethyl)- (3.27%), 4h-1,3,2-dioxaborin, 2-ethyl-4-met hyl-4,6-bis(2-methylpropyl)- (3.19%), vitamin e(2.97%), etc. The results of function analyses suggested that the benzene/ethanol extractives of both E. camaldulensis and E. urophylla leaves were abundant in materials of noble natural biomedicines.
