ChemInform Abstract: Further Quinoidal Derivatives from Rubia cordifolia L

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.
