Lunatin
Lunatin (3-methoxy-1,6,8-trihydroxyanthraquinone) is a derivative of anthraquinone. It is produced by the ''Senna reticulata'' tree and can be extracted by soaking the bark in alcohol. Lunatin is also produced by the fungus ''Curvularia lunata ''Cochliobolus lunatus'' is a fungal plant pathogen that can cause disease in humans and other animals. The anamorph of this fungus is known as ''Curvularia lunata'', while ''Cochliobolus lunatus'' denotes the teleomorph or sexual state. They ar ...'' which inhabits a marine sponge.

Anthraquinone
Anthraquinone, also called anthracenedione or dioxoanthracene, is an aromatic organic compound with formula . Isomers include various quinone derivatives. The term anthraquinone however refers to the isomer, 9,10-anthraquinone (IUPAC: 9,10-dioxoanthracene) wherein the keto groups are located on the central ring. It is a building block of many dyes and is used in bleaching pulp for papermaking. It is a yellow, highly crystalline solid, poorly soluble in water but soluble in hot organic solvents. It is almost completely insoluble in ethanol near room temperature but 2.25 g will dissolve in 100 g of boiling ethanol. It is found in nature as the rare mineral hoelite. Synthesis There are several current industrial methods to produce 9,10-anthraquinone: # The oxidation of anthracene. Chromium(VI) is the typical oxidant. # The Friedel-Crafts reaction of benzene and phthalic anhydride in presence of AlCl3. o-Benzoylbenzoic acid is an intermediate. This reaction is useful for produc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Senna Reticulata
''Senna reticulata'', the ''mangerioba grande'' or ''maria mole'' in Portuguese, is a pioneer tree species found on highly fertile floodplains in South America. It has some medicinal uses, but is regarded by farmers as a noxious weed, named ''matapasto'' (meadow killer) due to its ability to grow fast and outshade neighbouring plants. Uses It is used in the local folk medicine for liver problems and rheumatism. 1,3,8-Trihydroxyanthraquinone is an organic compound found in alcoholic extracts of the wood of the plant. The extract also contains, among other products chrysophanol (1,8-dihydroxy-3-methylanthraquinone), physcion (1,8-dihydroxy-3-methyl-6-methoxyanthraquinone), aloe-emodin (3-carbinol-1,8-dihydroxyanthraquinone), lunatin (3-methoxy-1,6,8-trihydroxyanthraquinone), emodin (6-methyl-1,3,8-trihydroxyanthraquinone), and chrysophanol-10,10'-bianthrone.Santos Rogério Nunes dos, Silva Maria Goretti de Vasconcelos and Braz Fihlo Raimundo (2008).

Curvularia Lunata
''Cochliobolus lunatus'' is a fungal plant pathogen that can cause disease in humans and other animals. The anamorph of this fungus is known as ''Curvularia lunata'', while ''Cochliobolus lunatus'' denotes the teleomorph or sexual state. They are, however, the same biological entity. ''Cochliobolus lunatus'' is the most commonly reported species in clinical cases of reported ''Cochliobolus'' infection. Morphology Macroscopic features of ''C. lunatus'' include brown to black colour, hairy, velvety or woolly texture, and loosely arranged and rapidly growing colonies on potato dextrose agar medium. Microscopically, there is great variety in the arrangement of the septate conidiophores, as they can be isolated or in groups, straight or bent, show simple or geniculate growth pattern, and vary in colour ranging from pale to dark brown. Conidiophore length can reach 650 μm and are often 5-9 μm wide, with swollen bases ranging from 10-15 μm in diameter. Conidia develop at the tips a ...
