The IR spectrum of the purified sample shows characteristic peaks of-OH between 3609-3288 cm-1, COOH between 1635-1617 cm-1 and ether linkage at 1419 cm- 1. The intrinsic viscosity of plantgopsyllium mucilage was found to be 1.29 dL/g. The pH values of 100 mL aqueous solution having different concentrations of plantago psyllium mucilage were found to be in the range of 7.11 to 7.26.
