Summary: Aervfuranoside (1), a new chlorinated dibenzofuran
glycoside together with ten (2-11) known compounds were isolated from ethyl acetate soluble fraction of methanolic extract of the flowers of Aerva javanica.
The ameliorative effect of Vc in the glutathione system of U373 cells might have been expected, given the presence of usnic acid in the extract; this dibenzofuran
is known to have beneficial effects on antioxidant enzymes and to increase the content of GSH in a model of indomethacin-induced decline of antioxidant capacity in gastric tissue of rats (Odabasoglu et al.
17 Gladen reported one out of 10 mothers in Taiwan (Yusheng accident) who were heavily exposed to environmental toxin polyhalogenetated aromatic hydro- carbons (PCB), polychlorinated dibenzofuran
(PCDF) gave birth to infants having natal teeth.
The relative abundance of dibenzothiophene (SF) in TFs, which include fluorene (F), dibenzothiophene (DBT) and dibenzofuran
(DBF), is very high, even up to 78.
On the other hand, cyclopentenediones, furans, furfurals, levoglucosenone and dibenzofuran
originate from fresh and/or degraded carbohydrates (Buurman and Roscoe 2011).
accolens (Staiger & Kalb, 1995) which contains epithecial pigment haematommone and the medullary dibenzofuran
These papers represent some of the latest developments and covers some surprisingly multidisciplinary topics, such as the elucidation of electron-transfer pathways in copper and iron proteins by pulse radiolysis; peptide- or protein-cleaving agents based on metal complexes; the structure of coordination polymers of the lanthanide elements; the supramolecular chemistry of gases; the organometallic chemistry of Rh-, Ir , Pd- and Pt-based radicals; unique complexes in the diverse world of metal-alkyne chemistry; oxygen activation chemistry of Pacman and Hangman porphyrin architecture based on xanthene and dibenzofuran
spacers; metal-containing nucleic acid structures based on synergetic hydrogen and coordination bonding; and bispidine coordination chemistry.
1993, Polychlorinated dibenzo-p-dioxin and dibenzofuran
levels and patterns in samples from different Swedish industries analyzed within the Swedish Dioxin Survey.
The airborne concentrations of compounds commonly present in creosote (indene, naphthalene, 2-methylnaphthalene, 1-methylnaphthalene, biphenyl, acenaphthene, dibenzofuran
, and fluorine) were determined for all air samples tested.
Quinoline, 2-naphthol, dibenzofuran
, and phenanthrene showed complete compatibility.
LRAPA's permit to Baxter lets the firm emit up to a total of 5,320 pounds a year of federally listed hazardous chemicals such as phenol, naphthalene, c-cresol, m-cresol and dibenzofuran
- all used in the process of treating wood.
