Anti Inflammation

The chemical constituents and anti-inflammatory activity of the essential oil from the leaf of Jatropha curcas L (Euphorbiaceae) collected from Nigeria are reported. The analysis of the chemical constituents of the essential oil was achieved by using gas chromatography (GC) and gas chromatography-mass spectrometry (GC-MS). All constituents of the essential oil, namely neophytadiene (35.8%), phytol (23.1%), trans-pinane (12.7%), 6,10,14-trimethyl-2-pentadecanone (12.3%) and citronellyl propanoate (11.2%), were present in significant amounts. The anti-inflammatory activity of the leaf oil was determined on Wistar rats using egg-albumin as phlogistic agent; significant inhibition ( P< 0.05) was shown at a dose of 2%, v/v. Percentage inhibition of the anti-inflammation increased steadily to 76.6% in the 4th hour.

Detailed chemical constituents of essential oil from the Pterocephalus hookeri leaves and its antimicrobial activities were investigated in this study. The essential oil, obtained by hydrodistillation, was characterized by gas chromatography-flame ionization detection and gas chromatography-mass spectrometry analyses. Among the 90 identified compounds, hexadecanoic acid (21.27%), phytol (8.03%), furfural (7.08%), oleic acid (5.25%), and phytone (4.56%) were the major components. In the antimicrobial assay, the essential oil showed strong inhibitory activities against Escherichia coli, Candida albicans, and Staphylococcus aureus with minimum inhibitory concentration values of 31.3, 62.5, and 125 µg/mL, respectively. To our knowledge, this is the first report concerning chemical composition and antimicrobial activities of the essential oil from Pterocephalus hookeri.

Abstract The objective of current study was to determine the chemical constituents and fumigant toxicity of essential oil isolated by hydro-distillation from dry fruit of bitter fennel (Foeniculum vulgare Miller). The chemical composition of the essential oil was assessed by gas chromatography (GC) and gas chromatography-mass spectrometry (GC-MS). Constituents of the oil were determined as α-pinene (1.6%) and limonene (3.3%), fenchone (27.3%), estragol (3.9%), and (E)-anethole (61.1%). The fumigant toxicity of the essential oil was tested on larvae of the stored product insect Trogoderma granarium Everts. The mortality of larvae was tested at different concentrations ranging from 31.2 to 531.2 μl/l air and at different exposure times (24 and 48 h). Probit analysis showed that LC50 and LC90 following a 48 h-exposure period for essential oil were 38.4 and 84.6 μl/l, respectively. These results showed that the essential oil from F. vulgare may be applicable to the management of populations of stored-product insects.

Essential oils obtained by hydrodistillation of leaves of two Nigerian species were analyzed for their constituents by gas chromatography (GC) and gas chromatography-mass spectrometry (GC-MS). The leaf oil of Ficus benjamina L. (Moraceae), collected during the day, contained high contents of α-pinene (13.9%), abietadiene (9.7%), cis-α-bisabolene (8.2%) and germacrene-D-4-ol (8.4%), while the night sample was dominated by germacrene-D-4-ol (31.5%), 1,10-di- epi-cubenol (8.8%) and hexahydrofarnesylacetone (8.3%). This could be a possible indication of differences in emissions of volatiles by F. benjamina during the day and night. The main compounds of Irvingia barteri Hook. f. (Irvingiaceae) were β-caryophyllene (17.0%), (E)-α-ionone (10.0%), geranial (7.6%), (E)-β-ionone (6.6%) and β-gurjunene (5.1%).

Essential oil is a hydrophobic concentrated liquid which contains volatile aroma compounds from plants. Bambusa vulgaris grows widely in the tropical and subtropical regions and has been reported to have different ethnomedicinal values such as antimalaria and antioxidant. It is also known to be an ornamental plant. The essential oil was extracted from both the fresh and dried leaves of Bambusa vulgaris by hydrodistillation method using a Clevenger apparatus. The chemical constituents of the essential oils were characterized using gas chromatography and gas chromatography-mass spectrometry. The essential oils obtained are colourless with an herbal odour giving a yield of 0.64 w/w for the fresh sample and 1.08 w/w for the dried sample. A total of thirty-nine (39) compounds were identified from the essential oils of both samples. The major constituents in the fresh leaves were 3-aminodibenzofuran (19.2%), ?-ocimene (11.1%), undecane (9.6%), tridecane (8.6%), [3,2-b] pyridin-6-octahydropyrano (7.1%), 2-mono laurin (6.9%) and vinyl decanoate (5.9%). Prominent compounds of the essential oil in the dried leaves were chlorophenoxymethylenimino sulfur pentafluoride (74.5%) and 2,2,6,6-tetramethyl-3,5-heptanedione (17.3%). Undecane, tridecane, hexadecane and octadecane were found both in the fresh and dried leaves. The chemical constituents of the essential oils from Nigeria Bambusa vulgaris were reported in this study for the first time to the best our knowledge and this could be useful in aromatherapy.

Alternanthera pungens Kunth commonly called khaki weed is from the family Amaranthaceae. It is a herbaceous perennial plant that has stems prostrate, rarely rising and about 10-50 cm long. The work was carried out due to the scarcity of information on the volatile constituents from the plant leaves despite works on the flower and other parts. The extraction of the essential oils from the dried leaves was carried out by the hydro distillation method using an all-glass Clevenger apparatus. The extracted oils were then analyzed using gas chromatography-mass spectrometry (GC-MS). A total of twelve constituents' representing 93.39% of A. Pungens oil with a yield of 0.4% (v/w) was obtained. The analysis of the GC-MS results of the leaf oil showed that it was dominated by â-ionone (42.18%) and hexahydrofarnesyl acetone (15.53%), others in trace amounts include; methyl palmitate (6.13%), 1octadecyne (4.72%), undecane (3.73%), para-mentha-1, 3, 8-triene (3.65%), isophytol (3.21%), ?cadinene (3.06%), 1, 2-dimethyl cyclooctene (3.05%), para-cymene (2.96%), phytol (2.67%) and neophytadiene (2.50%). The  common classes of compounds present in the leaves oil are aceto monocyclic monoterpenoid (42.18%), sesquiterpenoids (18.59%), hydrocarbons (11.50%), diterpenoids (8.38%), monoterpenes (6.61%) and fatty acids (6.13%).The constituents and the compositional pattern of essential oil identified from the leaves of Alternanthera pungens grown in Nigeria differ quantitatively and qualitatively from previously reported member of the genus and the presence of sesquiterpenoid as one of the major components of the oils justify the traditional use of the plants in treating pains, headaches and inflammations.

In this study, we evaluated the antimildew effects on paper of Plectranthus amboinicus (Lour.) Spreng leaf essential oil prepared through hydrodistillation. The oil was isolated with a Clevenger-type apparatus and then characterized through gas chromatography with flame ionization detection (GC-FID) and gas chromatography-mass spectrometry (GC-MS). A total of 43 compounds were identified, representing 99.5% of the oil. The main ingredients were carvacrol (50.0%), γ-terpinene (13.1%), and β-caryophyllene (11.3%). The leaf oil had excellent antimildew effects; its minimum inhibitory concentration (MIC) values against Aspergillus clavatus, A. niger, Cladosporium cladosporioides, Chaetomium globosum, Myrothecium verrucaria, Penicillium citrinum, and Trichoderma viride were 100, 200, 75, 75, 100, 150, and 150 μg/cm2 respectively. The leaf oil was further partitioned into 6 derivative fractions (PO1-PO6). PO2 had excellent antimildew effects on the abovementioned strains; at a concentration of 100 μg/cm2, all were 100% inhibited, except A. niger, which was 75.8% inhibited. Carvacrol, the main ingredient of PO2, was then isolated and used for antimildew tests; carvacrol had excellent antimildew activities. Since both P. amboinicus leaf essential oil and carvacrol were proved to have excellent antimildew effects on paper, they are worth further research and development.

The leaf essential oil of Otostegia fruticosa subsp. schimperi (Lamiaceae) was obtained by hydrodistillation and analyzed by gas chromatography – mass spectrometry (GC-MS). The major components in the leaf oil were τ-cadinol (9.3%), β-caryophyllene (8.8%), and bornyl formate (5.2%) as well as two unidentified diterpenoids (12.7% and 9.4%, respectively). The leaf oil was screened for antibacterial ( Bacillus cereus, Staphylococcus aureus, Escherichia coli, and Pseudomonas aeruginosa), antifungal ( Aspergillus niger, Candida albicans, and Botrytis cinerea), and cytotoxic (MCF-7 and MDA-MB-231) activity. The oil did not show antimicrobial or antifungal activity, but it showed very good cytotoxicity against MCF-7 (IC50 = 55.1 μg/mL) and MDA-MB-231 (IC50 = 70.3 μg/mL) cell lines.
