EXTRACTION, CHARACTERISATION, BIOACTIVITY, AND APPLICATION OF RAMBUTAN (Nephelium lappaceum L)

Abstract

In this study, parts consisting of spines, rind, seed coat and seed were sundried. The rind, seed coat and seed were powdered and subjected to ethanol extraction and subjected for characterization using Thin Layer Chromatography (TLC) and Fourier Transform Infrared Spectroscopy (FTIR). Anti-bacterial and Anti-fungal activity tests by well diffusion method in agar plates were performed. The powdered samples and spines were subjected to fiber extraction and subjected for FTIR analysis, and lignocellulosic content.  Fibers from spines and powdered samples were used for removal of crystal violet and chromium in adsorption study. Rind has antimicrobial properties against S. aureus, E. coli, and C. albicans. Seed has antibacterial property against E. coli. Fibers of spine, rind, seed coating and seed all showed highest content of lignin and showed some adsorbent property.
