Abstract
Essential oils obtained by hydrodistillation, using an all-glass apparatus, from the aerial parts, fruits and roots of Laportea aestuans (L.) Chew were analyzed using GC and GC-MS. From the oil of the aerial parts, 27 out of the 33 detected compounds, representing 95.1% of the total oil, were characterized. For the fruit oil, 10 out of 12 detected compounds were identified (89.3% of total), and for the root oil 19 of the 22 compounds (98.6%). The dominant components of the oil of the aerial parts were methylcyclohexane (20.9%), isodecyl octyl 1,2-benzenedicarboxylate (9.2%), di-n-octyl phthalate (9.0%), bis(7-methyloctyl)phthalate (7.0%), and toluene (6.9%); in the fruit oil, butyl 8-methylnonyl-1,2-benzenedicarboxylate (14.6%), 8-decyloxy-3-phenyl-2,4,7-trioxabicyclo[4.4.0]dec-9-ene (13.7%), dicyclohexyl-1,2-benzene dicarboxylate (13.6%), didodecyl phthalate (12.0%), and butyl-8-methylnonyl-1,2-benzenedicarboxylate (11.3%); and in the root oil, di-n-octyl phthalate (36.8%), butyldecyl-1,2-benzenedicarboxylate (7.5%), bis(2-ethylhexyl)hexanedioate (6.4%), butyl-2-ethylhexyl-1,2-benzenedicarboxylate (5.4%), and bis(2-ethylbutyl)-1,2-benzenedicarboxylate (5.0%)].
