Anthraquinones are a large family of secondary metabolites (SMs) that are extensively studied for their diverse biological activities. These activities are determined by functional group decorations and the formation of ...

The inner-ring oxidation of anthracene over V2O5/SiO2 catalyst was investigated at various oxygen concentrations, contact times of the reactants and reaction temperatures. Up to 90% yield to 9,10-anthraquinone is obtained ...

Photodynamic therapy has been applied for the treatment of many diseases, especially skin diseases. However, poor aqueous solubility and toxicity of some photosensitizer drugs are the main disadvantages for their direct ...

Studies undertaken on isolated photosensitizing agents from Heterophyllaea pustulata, a photo-toxic plant, which natural habitat is the North-western part of Argentina, are presented here. The carried out ...

The electrochemistry reduction for the removal of Reactive Blue 4 (RB4) dye from aqueous solution using reticulated glassy carbon electrode is investigated. At pH < 8.0 the anthraquinone group of the RB4 dye are reduced ...

© 2017, Springer-Verlag Berlin Heidelberg. The study and characterization of old artifacts such as pigments requires the use of techniques that need a small amount of sample to perform the analysis because of the high value ...

Heterophyllaea Pustulata Hook. f. (Rubiaceae), commonly known as "cegadera", is a phototoxic native plant from South America, containing anthraquinones with important antibacterial, antiviral and anticancer activity. In ...
