Xanthopurposide, A New Anthraglycoside from Rubia tinctorum Rhizomes
Chemistry of Natural Compounds, 2021The new natural compound 3-hydroxy-1-O-[β-D-xylopyranosyl-(1→6)-β-D-glucopyranosyl]-anthraquinone, which we called xanthopurposide, was isolated from rhizomes of Rubia tinctorum L. (madder). Its structure was elucidated using PMR, 13C NMR, mass spectrometry, and UV spectroscopy.

Characterization of lucidin formation in Rubia tinctorum L.
Plant Physiology and Biochemistry, 2005In order to approach lucidin formation (a strong mutagen or a carcinogen) from a physiological standpoint, hairy roots of Rubia tinctorum L. were established by a transformation of Agrobacterium rhizogenes strain 15834 and cultured in a liquid woody plant medium without plant hormones. The anthraquinone pigment composition of the intact hairy roots was

Abstract The roots of Rubia tinctorum L. (madder) are the source of a natural dye. In this review for the first time all the different information on Rubia tinctorum available in the literature is summarised. The dye components are anthraquinones whichprobably contribute to the resistance of the plant against fungi in the soil.

Three hydroxymethylanthraquinone glycosides from rubia tinctorum
Phytochemistry, 1998Three hydroxymethylanthraquinone glycosides, in addition to the known compounds alizarin, lucidin-ω-ethyl ether, lucidin primeveroside and the iridoid asperuloside were isolated from the dried roots of Rubia tinctorum. The first three compounds were isolated for the first time from this species.

Antimicrobial activity of common madder (Rubia tinctorum L.)
Phytotherapy Research, 2006AbstractIn this study, ethanol, methanol, ethyl acetate and water extracts of Rubia tinctorum L. (Rubiaceae) were tested for antimicrobial activity by the disc diffusion method. From the present study it was found that Rubia tinctorum L. revealed antimicrobial activity against some Gram (+) and Gram (–) bacteria, yeasts, filamentous fungi and ...
