Two pentacyclic triterpenes from Rubia cordifolia

Phytochemistry, 1981
Abstract Rubicoumaric acid and rubifolic acid isolated from Rubia cordifolia have been shown to be 30-hydroxy-3β-p-hydroxycoumaryloxy-urs-12-ene-28-oic acid and 3β,30-dihydroxy-urs-12-ene-28-oic acid(30-hydroxyursolic acid) respectively on the basis of 1H NMR, 13C NMR and mass spectral and chemical evidence.

Anthraquinone production by callus cultures of Rubia cordifolia

Fitoterapia, 1999
Abstract Munjistin and purpurin were identified as the major components of anthraquinone pigments produced by callus cultures of R. cordifolia. Anthraquinone content in calluses was 0.62–1.22% (by dry wt.) depending on the source of explants. Selection of coloured aggregates yielded a cell line with twofold increase in anthraquinone production.

A prenyltransferase participates in the biosynthesis of anthraquinones in Rubia cordifolia

Plant Physiology
Abstract Anthraquinones (AQs) constitute the largest group of natural quinones, which are used as safe natural dyes and have many pharmaceutical applications. In plants, AQs are biosynthesized through two main routes: the polyketide pathway and the shikimate pathway.

[Alpha-glucosidase inhibitors from Rubia cordifolia].

Zhongguo Zhong yao za zhi = Zhongguo zhongyao zazhi = China journal of Chinese materia medica, 2009
To search alpha-glucosidase inhibitors from Rubia cordifolia.The alpha-glucosidase inhibitors were isolated by the column chromatographic techniques and the bioassay-guided method in vitro. A combination of MS and NMR spectroscopy was used to identify the chemical structures.

[New quinones in Rubia cordifolia L. Roots, III].

Planta medica, 2010
From roots of Rubia cordifolia L. four anthraquinones are isolated: 1-hydroxy 2-methoxy anthraquinone; 1,4-dihydroxy 2-methyl 5-methoxy anthraquinone or 1,4-dihydroxy 2-methyl 8-methoxy anthraquinone; 1,3-dimethoxy 2-carboxy anthraquinone and rubiadin.

Further quinoidal derivatives from Rubia cordifolia L.

Die Pharmazie, 2000
Two new quinoidal dimers, a new naphthohydroquinone anhydride, a known naphthoic acid ester derivative and two known benzoic acid derivatives were isolated from the chloroform fraction of a chloroform-methanol (1:1) extract of Rubia cordifolia L. The identification of these compounds was based on spectral analysis.
