“…The relatively high heritability coefficients calculated for some essential oil components informing whether a character is more influenced by genetic or other factors, confirm that the potential to produce a certain chemical pattern is genetically coded, but the gene expression will be induced or repressed by environmental factors also (Franz, 1993). The presence of geijerene and pregeijerene from the essential oil of the leaves C. odorata has also been reported quantitatively different in various countries (Bedi, Tonzibo, & Nguessan, 2001;Bedi, Tonzibo, Chopard, Mahy, & Nguessan, 2004;Joshi, 2013c;Owolabi et al, 2010;Pisutthanan et al, 2006). This study also found that the major compounds of P. mollis were the same with quantitative differences.…”

Abstract:Plectranthus is a large and widespread genus with a diversity of ethnobotanical uses. In traditional medicine P. mollis has been used against snakebites, respiratory stimulant and vasoconstrictor, cardiac depressant, cure for haemorrahage, treatment of mental retardation and rheumatism. P. mollis is reported to exhibit relaxant activity on smooth and skeletal muscles, and has cytotoxic and anti-tumour promoting activity, and can be used in the treatment of cancer. The aim of the present study was to identify chemical composition of the essential oil of P. mollis and to evaluate antimicrobial efficacy of the oil. The essential oil of the flowering aerial parts of P. mollis was obtained by hydro-distillation and analyzed by gas chromatography equipped with a flame ionization detector (GC-FID) and gas chromatography coupled with mass spectrometry (GC/MS). Twentyseven compounds were identified, which comprised 98.6% of the total constituents. The main compound was identified as fenchone (32.3%), followed by α-humulene (17.3%), piperitenone oxide (8.5%), cis-piperitone oxide (6.0%) and E-β-farnesene (5.9%). The oil was found rich in oxygenated monoterpenes type constituents (52.0%), followed by sesquiterpene hydrocarbons (40.2%), oxygenated sesquiterpenes (4.9%), and monoterpene hydrocarbons (1.5%). Antimicrobial activity of the essential oil of P. mollis was tested against six Gram-positive and eight Gram-negative bacteria, and three fungi, by using the tube dilution method. The oil was active against the tested Gram-positive and Gram-negative bacteria, and fungi at a concentration range of 0.065±0.008-0.937±0.139mg/mL, 0.468±0.069-3.333±0.527 mg/mL and 0.117±0.017-0.338±0.062mg/mL, respectively. The present study revealed that the oil constituents somehow were qualitatively similar and quantitatively different than earlier reports from different parts of the world. The essential oil of P. mollis has found to be antimicrobial activity which can be usefulness in the treatment of various infectious diseases caused by bacteria and fungi. Rev. Biol.

Abstract:The chemical composition of the essential oils of aerial parts and flowers of Chromolaena odorata (L.) R. M. King & H. Rob., collected from Western Ghats region, were obtained by hydrodistillation and analyzed by gas chromatography (GC) and gas chromatography/mass spectrometry (GC-MS). Fifty two and thirty four compounds were identified from aerial parts and flowers, representing 94.9 % and 95.2 % of the total oils, respectively. The essential oil from aerial parts was dominated by pregeijerene (14.2 %), epicubebol (9.8 %), cubebol (8.6 %), cis-sabinene hydrate (5.7 %), 10-epi-γ-eudesmol (3.8 %), germacrene-D-4-ol (3.6 %) and δ-cadinene (3.5 %), while germacrene D (24.8 %), geijerene (12.6 %), pregeijerene (12.5 %), cyperene (7.8 %), 10-epi-γ-eudesmol (4.7 %), α-muurolol (3.6 %) and khusimone (3.4 %) were identified as the major constituents of flowers oil of C. odorata.

“…To the best of our knowledge, only some researchers have studied the essential oil of E. odoratum [10,[12][13][14][15][16][17]. Chowdhury studied the essential oils obtained from the leaves of E. odoratum collected from Shillong Meghalaya, North-East India and found that the oil contained mainly caryophyllene oxide (18.34%) [12].…”
