Abstract
The potential presence of naturally occurring antimicrobials in petals of
flowers of Hibiscus sabdariffa L., (Malvaceae) was investigated against isolated eye
pathogens. Owing to the usage of these flowers in common folklore medicine, the
extracts of petals were screened for antibacterial activity against pathogenic microbes
isolated from the eyes of eye infected persons. Bioactive compounds were extracted by
cold extraction method, wherein Methanol, ethyl acetate and dichloromethane were used
as solvents. The antibacterial activity of the extracts was assessed by agar well diffusion
method. The study revealed that the extracts possessed antibacterial activity in a dose
dependent manner. Among the tested flower extracts of Hibiscus sabdariffa, DCM
extract showed better activity on most of the ocular pathogens tested. Hence the DCM
extracts of petals of the flowers of Hibiscus sabdariffa can be used to discover
antibacterial agent for developing new pharmaceuticals to treat eye infections.
