Isolation and characterization of inositol-containing glycosphingolipids from Aspergillus niger.
The glycophosphosphingolipids are a group of sphingolipids characterized by the presence of equimolar amounts of long-chain base and fatty acid (ceramide) and containing either one or two mol of inositol phosphate per mol of lipid. From one to several mol of sugar are also present. Glycophosphosphingolipids have been isolated from both plant and fungal sources. Work in this area had for years b...

Extraction of Flavonoids and Quantification of Rutin from waste Tobacco Leaves
The potential of tobacco waste as a viable source of medicinally important flavonoids like rutin has been investigated. Three flavonoids, apigenin, quercetin and rutin, have been isolated from waste tobacco leaves, and their identities have been confirmed by UV-visible, 1H-NMR and 13C-NMR spectroscopy. By using analytical HPLC, the amount of rutin present in the tobacco leaves, before and after...
متن کاملCharacterization of double-stranded ribonucleic acid in tobacco leaves.
Double-stranded RNA was isolated from tobacco leaves and characterized in terms of base composition, density, and nuclease resistance. Although its role in the plant's physiology is not clear, evidence was adduced that it is the product of the RNA-dependent RNA polymerase previously shown to occur in this and other plants. The fact that twice as much fully than partially double-stranded RNA app...
