In the recent years, many new excipients and modified preparations of existing excipients have been developed and introduced to the pharmaceutical field. These new excipients are found to be very useful for the formulation of various drug delivery systems. The main aim of the present investigation is to provide new sustained release excipient which, when incorporated into a final product, produces controlled release of active ingredient over an extended period of 12 hrs or more when the dosage form is exposed to G.I fluids in gastric environment. Okra pods are fruits of the plant Abelmoschus esculentus L. moench, family Malvaceae. Okra gum, which is a natural polymer, has advantage over synthetic and semi-synthetic polymers, in that it is cheap and easily available, non-irritant, biodegradable, biocompatible, and eco-friendly. In the present investigation the physico chemical, microbial and rheological properties of Okra gum powder are evaluated. Further Okra gum was subjected to accelerated stability studies according to ICH guidelines. Physico chemical properties like particle size distribution, surface characteristics, bulk density, tapped density, compressibility, flow properties, moisture content, PH, volatile acidity, swelling and water absorption properties are carried out. DSC and Infrared spectroscopy are performed on Okra gum powder.
