Description

Citrus paradisi peels were successively extracted with hexane, chloroform, acetone and methanol
using a Soxhlet extractor for 8 h each. Thin layer chromatography (TLC) of hexane and chloroform extracts
showed three spots with different concentrations; hence
both the extracts were mixed and fractionated into alcohol
soluble and insoluble fractions. Naringin was isolated
from acetone and methanol extracts by column chromatography
and its structure was confirmed by 1H and 13C NMR spectroscopic studies. Antibacterial activity of
these fractions was evaluated against different bacteria.
The alcohol soluble fraction was found to possess maximum
activity followed by hexane extract. Extracts were
more effective against Gram-positive than Gram-negative
bacteria.
