| Abstract | ||||
| From the butanol fraction of the chloroform-methanol ext. (1:1) of the dried roots of Rubia cordifolia L, several compds. were isolated and identified viz, the saponins hederagenin-3-O-α-L-arabinopyranoside and 3-O-α-L-arabinopyranosyl-hederagenin-28-Oβ-D-glucopyranosyl-(1→6)-β-D-glucopyranoside ester, the naphthohydroquinone glycosides: 2-carbomethoxy-3-prenyl-1,4-naphthohydroquinone 4-O-β-glucoside and 2-carbomethoxy-3-prenyl-1,4-naphtho-hydroquinone 1,4-di-O-β-glucoside, the anthraquinone glycosides: 1-hydroxy-2-hydroxymethyl-9,10-anthraquinone-11-β-D-glucopyranosyl-(1→6)-β-D-glucopyranoside, 2-methyl-1,3,6-trihydroxy-9,10-anthraquinone-3-O-α-rhamnopyranosyl (1→2)-(4'-O-acetyl)-β-glucopyranoside and 2-carbomethoxy, 1,3-dihydroxy-9,10-anthraquinone-3-O-α-rhamno-pyranosyl-(1→2)-β-glucopyranoside and adenosine. The identification of the isolated compds. was done using different phys., chem. and spectral methods | ||||
