VOLATILE CONSTITUENTS OF THE AERIAL PARTS OF TERATAENIUM LASIOPENTALUM (BOISS.) MANDEN., STEMS AND LEAVES OF DOREMA AMMONIACUM D.DON. AND LEAVES, FRUITS AND STEMS OF LEUTEA PETIOLARE (DC.) M.PIMEN FROM IRAN

Protium aracouchini (Aubl.) Marchand [sin Icica aracouchini Aubl.], which occurs in the Adolpho Ducke Forest Reserve, in the Brazilian Amazon, was evaluated for the presence of galls, for resin exudation and the composition of the essential oils from the aerial parts and the resin. The experiment to stimulate the exudation of resin from the trunk was conducted using a 2-chloroethylphosphonic acid solution. The resin produced after 40 days and the aerial parts had their essential oils extracted in a Clevenger apparatus and the volatile chemical constituents were analyzed using GC/MS. The non-oxygenated sesquiterpenes α-copaene (21.15%) and α-gurjunene (13.69%), in addition to the oxygenated sesquiterpene spathulenol (10.32%), were detected as the majority constituents of the essential oil of the leaves, and a concentration similar to that of α-gurjunene was found in the branches (13.28%). The resin essential oil showed a high concentration of hydrocarbon monoterpenes (76.49%) with a predominance of α-pinene (17.57%) and limonene (46.11%). Four gall morphotypes were found associated with this species. The present study reports for the first time information on the volatile constituents and the resinous potential of P. aracouchini, and registers the morphotypes of the galls that help in the taxonomy of the species.

Main Components

Eupatoriurn odoratumaerial parts were extracted with ligarine and the volatile constituents isolated were analyzed by gas chromatography (GC) and gas chromatography/mass spectrometry (GC/MS). Volatile constituents were isolated from the ground aerial parts ofE. odoratumby ligarine extraction and analyzed by gas chromatography (GC) and gas chromatography/mass spectrometry (GC/MS). As a result, a total of fifteen compounds represented all of the extract were identified, amongst nine of fifteen compounds were sesquiterpenes. Esters and sesquiterpenes were found to compose three major chemotype accounted for 58.58% and 30.80% of the constituents, respectively. The main components was demonstrated to be dibutyl phthalate (39.73%), 11,14,17-eicosatrienoic acid, methyl ester (13.20%), (S)-spiro [4.nona-1,6-diene (6.80%), 1,2-benzenedicarboxylic acid, bis (2-methylpropyl) ester (5.65%) andcis-Z-α-bisabolene epoxide (5.56%). In addition, some pharmaceutical components such as α-cadinol and germacrene D were discovered. Antioxidant activity of the extract was assessed by the free radical scavenging (DPPH). The study offers theoretic basis for pharmaceutical utilization of the medicinal plantE. odoratum.
