Analysis of essential oil of eaglewood tree (Aquilaria agallocha Roxb.) by gas chromatography mass spectrometry

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

Screening of organochlorine insecticides (DDT and heptachlor) in dry fish available in Bangladesh

The concentrations of organochlorine insecticides DDT and heptachlorwere investigated to estimate the current status of insecticidesused in dry fish. The most popular dry fish– ribbon fish (Chhuri),shrimp (Chingri) and bombay duck (Loittya) were selected for thisstudy and these dry fishes were collected from different markets ofDhaka and Chittagong. The range of DDT used in all the samples was3.038 ppb to 874.966 ppb. The range of DDT in ribbon fish 131.611 ppb to 149.430 ppb, in shrimp 3.038 ppb to 318.206 ppb and in bombayduck 61.918 ppb to 874.966 ppb was found. The range of heptachlorused in all the samples was 0.682 ppb to 5.464 ppb. The range ofheptachlor in ribbon fish 1.710 ppb to 2.306 ppb, in shrimp 0.682 ppbto 3.806 ppb and in bombay duck 1.762 ppb to 5.464 ppb was found.The heptachlor was not found in ribbon fish (CTG-2), shrimp (DHK-2and CTG-1) and bombay duck (DHK-1). The concentration of heptachlorin dry fish compare to DDT was found too much less
