Cytotoxic anthraquinones from the stems of Rubia wallichiana Decne.
From the stems of Rubia wallichiana DECNE, thirty-four structurally related compounds were isolated and identified. Three of them, namely rubiawallin-A (1), -B (2), and -C (3), constitute the first report of their occurrence from the natural source. Their structures were determined by comprehensive analyses of their 1D and 2D NMR, and electron impact (EI) mass spectral data. Furthermore, an in ...
متن کاملConstituents of the roots of Rubia yunnanensis.
Four new naphthohydroquinones, rubinaphthins A (1), B (2), C (3), and D (4), together with 11 known compounds were isolated and characterized from the roots of Rubia yunnanensis. The structures of 1-4 were elucidated by spectral analysis and chemical transformation.
متن کاملAnthraquinones of the roots of Pentas micrantha.
Pentas micrantha is used in the East African indigenous medicine to treat malaria. In the first investigation of this plant, the crude methanol root extract showed moderate antiplasmodial activity against the W2- (3.37 μg/mL) and D6-strains (4.00 μg/mL) of Plasmodium falciparum and low cytotoxicity (>450 μg/mL, MCF-7 cell line). Chromatographic separation of the extract yielded nine anthraquino...
متن کاملAnticancer constituents from the roots of Rubia cordifolia L.
Activity-directed isolation of the methylene chloride fraction of the roots of Rubia cordifolia L. resulted in the identification of a new epoxymollugin (3) and eight known compounds (1, 2, 4-9). The structures of the compounds were elucidated from chemical and spectroscopic evidence. In addition, their topoisomerase I and II inhibitory activities and cytotoxicities were measured.
متن کاملAnthraquinones and Anthraquinone Glycosides from the Roots of Cassia multijuga*
From the ethanolic extract of the roots of Cassia multijuga two anthraquinones C15H10O4 (Qi) and C16H12O6 (Q2) and two anthraquinone glycosides C28H32O15 (Si) and C27H30O14 (S2) have been isolated. Homogeneity and purity of these compounds were established by chromatography. Anthraquinone (Qi) has been identified to be 1:3-dihydroxy-2-methyl anthraquinone (rubiadin) by standard colour reactions...
