Photolysis of Heptachlor andcis-chlordane and toxicity of their photoisomers to animals
Heptachlor andcis-chlordane are converted to their corresponding photoisomers and several minor products on exposure to low intensity (longwave) ultra-violet light. This photolysis can also take
Fate of 14C-cis-chlordane in goldfish, Carassius auratus (L.).
Isolation and structural elucidation of griffithine by 1D and 2D NMR techniques
The isolation and structure elucidation of a novel dimeric alkaloid, griffithine, from the leafy shoots of Sophora griffithii Stock (Papilionaceae) is described. The alkaloid possesses a 12‐membered
Oxidative dehydrochlorination of heptachlor by Daphnia magna
Abstract [14C]Heptachlor is metabolized by the freshwater microcrustacean, Daphnia magna, to 1-hydroxychlordene, 1-ketochlordene, 1-hydroxy-2,3-epoxychlordene, and their glucosides, sulfates, and
Phytochemical Studies on Swertia cordata
Two new xanthones have been isolated from Swertia cordata and their structures were determined by using 2D-nmr techniques such as HMQC, HMBC, and HOHAHA experiements.
Phenolics from Colchicum decaisnei
Abstract Colchicum decaisnei has yielded three new compounds, namely, dibenzo[ b , f ][1,5]dioxocin, 4,6-dimethoxy-3,7-dimethyl coumarin and 3- O -demethyl- N -desacetyl- N -formyl-β-lumicolchicine,
Metabolism of14C-heptachlor in goldfish (Carassius auratus)
Goldfish injected with14C-heptachlor (38.2 μg/44 g fish) eliminated about 18% of the dose in 10 days. Analyses of the fish at the end of 10 days revealed the presence of five compounds of which 91.2%
