چکیده
A new red anthraquinone, draculone, has been isolated from the corticolous tropical lichen Melanotheca cruenta (= Trypethelium cruentum = Pyrenula cruenta) together with minor quantities of the known anthraquinone pigment haematommone. The structure of draculone was determined as 2-acetyl-1,3,4,6,8-pentahydroxyanthraquinone by spectroscopic methods.

متن کاملMetabolites from Aspergillus versicolor, an endolichenic fungus from the lichen Lobaria retigera.
Three new anthraquinone derivatives (1-3) and one new artifact (4) were isolated, along with six known anthraquinone derivatives (5-10) and three xanthones (11-13), from a culture of an endolichenic fungus, Aspergillus versicolor, that was isolated from the lichen Lobaria retigera. The structures of these substances were determined on the basis of 1D and 2D (COSY, HMQC, and HMBC) NMR and MS ana...

We have reported here a simple, low cost preparation of four new adducts from some anthraquinone disperse dyes with functionalized multi-walled carbon nanotubes in the presence of azochromophore. The structural differences between the final products are evaluated by visual dispersion test, UV-Vis Spectroscopy, Fourier transforms infrared, Raman, nuclear magnetic resonance and thermal gravimetri...

Five new 1-hydroxy-2-(1-alkyloxymethyl)-9,10-Anthraquinones (9a-e) have been prepared. Selective nitration of 2-methyl-9,10-anthraquinone, reduction to the corresponding amine, diazotization and treatment by sulfuric acid solution afforded the 1-hydroxy-2-methyl-9,10-anthraquinone in good yield as the key intermediate. Reaction with dimethylsulphate/K2CO3 and subsequen...
متن کاملStudying a New Infrared Reflective Polymer Coating
Although, that the solar energy is important for life continuity, there is need to protect large buildings from these radiations in summer and if the buildings are permitted to take these radiations, the cost of cooling will be too much. One of the most effective methods used to solve this problem is to coat buildings with specific pigments that reflect the solar infrared radiation. This wo...
