Evaluation of antibacterial activity of Jatropha curcus seed oil
Journal Title: International Journal of Life Science - Year 2018, Vol 6, Issue 2
Abstract
This study investigated the antibacterial activities of hexane extracts of Jatropha curcas essential oil on the microorganisms Staphylococcus aureus, E.coli, Klebsiella, Streptomyces griseus and Serratia marcescens by agar diffusion method. Phytochemical screening of the extracts was also determined. Phytochemical screening revealed the presence of steroids, tannins, flavonoids, alkaloids, while phenol and reducing sugars were absent.The hexane extracts of J. curcus seed oil showed highest inhibition of 33 mm against Staphylococcus aureus, Klebsiella pneumonia, followed by Escherichia coli (31 mm), Sterptomyces griseus (22 mm) and the least inhibition was recorded in Serratia marcescens (18mm). No inhibition was observed in the negative control. The results show the seed oil extract of J. curcus can be effectively used as potential candidate for controlling microbes and can be considered eco-friendly.
