متن کاملIsolation 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...
