Extraction of Neem, Justicia adhatoda & Black pepper and Synthesis of extraction loaded Gum acacia / Carboxymethyl cellulose composite film their characterization and antibacterial activity

Abstract

In this work, the composite film based on Carboxy methyl cellulose (CMC) and Gum Arabic (GA) were prepared by solution casting method. Calcium chloride was used as a crosslinking agent with different ratios. The physical properties of the composite film were investigated in terms of swelling percent (%) and the structure of the composite film was characterized by Fourier transform infrared spectroscopy. Antimicrobial activity in leaf extract of neem (Azadirachtolides) against human pathogenic bacteria. E. coli, extract showed a broad spectrum of very significant antibacterial activity by producing a clear zone of inhibition against, E. coli.
