Isolation and extraction of ruberythric acid from Rubia tinctorum L. and crystal structure elucidation.
Madder (Rubia tinctorum L.) has been exploited as a dye throughout history. The roots of the plant are very rich in the highly coloured glycosidic compounds ruberythric acid and lucidin primeveroside, alongside the corresponding aglycons which can be readily formed by deglycosylation, particularly during extraction. Supported by (1)H and (13)C NMR data, the conclusive X-ray crystal structure of...
متن کاملIsolation and extraction of lucidin primeveroside from Rubia tinctorum L. and crystal structure elucidation.
Madder (Rubia tinctorum L.) has been used as a dye for over 2000 years with alizarin and purpurin the major natural dyes analysed from extractions undertaken. The use of ethanol as the solvent in the extraction process produced an extract that yielded four anthraquinone compounds lucidin primeveroside, ruberythric acid, alizarin and lucidin-ω-ethyl ether. Gravitational separation of the extract...
متن کاملUV-Vis spectroscopic study of the stability of Silver nanoparticles in monovalent and divalent electrolyte solutions
Nanotechnology has been advanced since the last decades. Among all nanomaterials that have been developed, nanosilver is the most frequently used nanoparticles. Its release into natural water bodies is inevitable due to its broad applications. Nanosilver (nAg) was prepared via Tollens method using. The morphology, size distribution and average size of the obtained nAg was characterized using Tr...
