Identification And Quantification

Toxic normal hydrocarbon (NH), nonadecane in the methanolic extract of the whole of cabbage samples collected from different districts of Bangladesh was analyzed by GC-MS. It was observed that NH deposition on the samples takes place in different morphological parts of the biological materials. The NH, nonadecane, was found in the cabbage samples collected from the highway road side by the extraction of methanol. The identification and quantification of the title compounds have not been reported previously in the cabbage sample.   Keywords: Cabbage; brassica oleracea var. capitata f. alba; quantification; normal hydrocarbon, nonadecane, GC-MS

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.

Kalanchoe Pinnata

The essential oil from the leaves of Kalanchoe pinnata (Lam.) Pers. (Crassulaceae), collected in the Venezuelan Andes, was obtained by hydrodistillation and its composition determined by gas chromatography (GC) and gas chromatography/mass spectrometry (GC/MS). Nineteen compounds were identified, representing 95.2% of the oil. The most abundant components were α-curcumene (44.7%), 1-octen-3-ol (18.1%), β-curcumene (4.9%), and β-caryophyllene (3.7%).
