Abstract: Phalsa (Grewia asiatica) is an indigenous, underutilized, edible fruit of the family Tiliaceae which possess huge nutritional potential and great medicinal value. In the present study, an attempt has been made to establish the preliminary FT-IR profile of pulp and seed powder of phalsa fruit subjected to drying in lyophilizer.Lyophilized fruit powder (seed & pulp) were analysed in mid infrared regionof FT-IR spectroscopy for functional group identification. Resulted IR spectrum revealed the presence of various functional groups viz: alcohol, alkanes, alkenes, alkyne, aldehyde, ketone, primary amine, carboxyl group, alkyl halide, halogen, bioactive fraction and aromatic rings in both the samples. Functional groups commonly present in the pulp and seed of fruit indicates similar uses of both portions in food and medicinal applications. This investigation will provide a basic database on preliminary information of chemical constituents and their scope for further study.
