Article: Chemical constituents of essential oils from aerial parts of Adenosma capitatum and Limnophila aromatica
[show abstract] [hide abstract]
ABSTRACT: The essential oils were isolated by hydrodistillation from the aerial parts of Adenosma capitatum and Limnophila aromatica and were analyzed by gas chromatography mass spectrometry (GC-MS). Forty six and thirty components were identified, representing 98.8% and 99.3% of the total oils respectively. Oil of A. capitatum rich in limonene (24.74%), fenchone (21.59%) and 2-carene (17.64%). On the other hand, L. aromatica rich in Z-ocimene (39.21%), terpinolene (17.24%) and camphor (12.89%).Bangladesh Journal of Pharmacology. 01/2010; -
Article: Chemical investigation of the leaf and rhizome essential oils of Zingiber zerumbet (L.) Smith from Bangladesh
[show abstract] [hide abstract]
ABSTRACT: Zingiber zerumbet (L.) Smith leaf and rhizome oils, obtained by hydrodistillation, were analyzed by gas chromatography mass spectroscopy (GC-MS). Twenty-nine components were identified in the leaf oil. The major components were zerumbone (36.98%); a-caryophyllene (16.35%) and camphene (9.24%). Thirty components were identified in rhizome oil with the main components being in zerumbone (46.83%); a-caryophyllene (19.00%) and 1,5,5,8-tetramethyl-12-oxabicyclo[9.1.0]dodeca-3,7-diene (4.28%). The compositions of both oils varied qualitatively and quantitatively.Bangladesh Journal of Pharmacology. 01/2009; -
Article: Analysis of essential oil of eaglewood tree (Aquilaria agallocha Roxb.) by gas chromatography mass spectrometry
[show abstract] [hide abstract]
ABSTRACT: The study was carried out to find out the differences in composition of oils obtained from healthy, naturally infected and artificially screws wounds eaglewood (Aquilaria agallocha Roxb.) using gas chromatography mass spectrometry (GC-MS) analysis. Natural healthy plants agar contained octacosane (19.83%), naphthalene, 1,2,3,5,6,7,8,8a-octahydro-1,8a-dimethyl-7-(1-methylethenyl)-, [1R-(1.alpha.,7.beta.,8a.alpha.)]- (12.67%), 5-isobutyramido-2-methyl pyrimidine (13.52%), caryophyllene oxide (11.25%) and (.+-.)-cadinene (5.46%). Natural infected plants agar (super agar) contained cycloheptane, 4-methylene-1-methyl-2-(2-methyl-1-propen-1-yl)-1-vinyl- (46.17%), caryophyllene oxide (33.00%) and 7-Isopropenyl-4a-methyl-1-methylenedecahydronaphthalene (20.83%). Artificially screw injected plants agar contained diisooctyl phthalate (71.97%), 1H-Cycloprop[e]azulen-4-ol, decahydro-1,1,4,7-tetramethyl-, [1ar-(1a.alpha.,4.beta.,4a.beta., 7.alpha., 7a.beta., 7b.alpha.)]- (9.16%), hexadecanoic acid (7.05%), naphthalene, 1,2,3,5,6,7,8,8a-octahydro-1,8a-dimethyl-7-(1-methylethenyl)-, [1R-(1.alpha.,7.beta.,8a.alpha.)]- (6.45%) and aristolene (5.36%). This study showed a marked difference in the oil compositions among the treatments with regards to their quality.Bangladesh Journal of Pharmacology. 01/2009; -
Article: Volatile constituents of essential oils isolated from leaf and rhizome of Zingiber cassumunar Roxb.
[show abstract] [hide abstract]
ABSTRACT: The composition of the essential oil of Zingiber cassumunar Roxb. from Bangladesh was examined by gas chromatography mass spectroscopy (GC-MS). Sixty-four components were identified in leaf oil and 32 components were identified in the rhizome oil, accounting for 94.60% and 98.56% of the total yields, respectively. The main component in leaf oil was sabinene (14.99%), beta-pinene (14.32%), caryophyllene oxide (13.85%) and caryophyllene (9.47%). On the other hand, rhizome oil contained triquinacene 1,4-bis (methoxy) (26.47%), (Z)-ocimene (21.97%) and terpinen-4-ol (18.45%). The compositions of both oils varied qualitatively and quantitatively.Bangladesh Journal of Pharmacology. 01/2008;
