Abstract: ‘Indian Madder’ (Rubia cordifolia L.) has wide range of pharmacological properties. In the present study, an attempt was made to identify the pharmacognostic features of various parts of R. cordifolia to differentiate it from adulterants. The organoleptic characters, proximate analysis, physio-chemical behavior of powders were recorded. The stomatal index, palisade ratio and ash value were shown to be characteristic under standard conditions. Optical activity of various R. cordifolia extracts under visible and UV light (254 nm and 366 nm) were recorded. Phytochemical studies revealed the presence of anthraquinone and other metabolites in different plant parts. Powder analysis showed trace red colour in root powder under most of the standard test conditions. Phytochemical and pharmacognostic records evolved in the present study can be used for framing standard parameters for the proper identification of raw materials of R. cordifolia.
