Comparative study of Phytochemical Screening and Antibacterial Activity of Curcuma longa (L.) and Curcuma aromatica (Salib.)

Abstract

Curcuma longa (L.) and Curcuma aromatica (Salib.) are medicinal plants belongs to family Zingiberaceae family. Curcuma aromatica (Salib.) and Curcuma longa (L.) are rich in phtyochemicals. They show the presence of alkaloids, flavonoids, tannins and terpenoids. Due to presence of these phytochemicals Curcuma longa (L.) and Curcuma aromatica (Salib.) shows antibacterial activity. The Ethanolic and Methanolic extracts of Curcuma longa (L.) and Curcuma aromatica (Salib.) were subjected to microbial susceptibility test using the agar well diffusion against Escherichia coli. Methanolic extract of Curcuma aromatica (Salib.) shows inhibition zone of 7.5mm at highest concentration of 20mg.
