In the present study, the rhizome of Maranta arundinacea L., Arrowroot, was selected for a rich source of starch for the preparation of biofilm. Firstly, some physicochemical properties of the selected sample were determined by AOAC method. Furthermore, the elemental analysis of the selected sample was carried out by Energy Dispersive X-ray Fluorescence (EDXRF) spectroscopy. Moreover, antimicrobial activities of various solvent extracts were examined by Agar well diffusion method on six tested organisms. And then, the qualitative determination of starch tests such as Iodine test and Tannic acid test were done. In addition, starch from Arrowroot powder was isolated and confirmed by FT IR spectrum. Finally, starch biofilms were prepared by using isolated starch and various ratios of plasticizers PVA, PEG, and Sorbitol. The characterizations of seven kinds of prepared biofilms were measured.
