A Study of Antibacterial Activity of Ginger Rhizome Extracts

Abstract

Ginger is a medicinal plant of the family Zingiberaceae Ginger is widely used as a Spice as well as condiments in many countries of the world (Gao et al., 2010). Ginger has been used for medicinal purposes not only in India but in China too. (Super detha et al., 2011, Salman, et al., 2012, Yeh et al., 2014). For the examination of antibacterial properties, we used 4 standard bacteria -Escherichia coli [MCC 3099], Streptococcus pneumoniae [MCC 2424], Bacillus subtilis [MCC 2010], Klebsiella pneumoniae [MCC 3094]. The MIC (minimum inhibitory concentration) was performed for methanol extraction of Zingiber officinale's rhizome by ELISA. The presence of alkaloids, cardiac glycosides, flavonoids, saponins, etc. was also examined during phytochemical analysis. The presence of antioxidants has been determined by DPPH radical scavenging capacity, Antioxidant potential IC50, and chromatogram of High-Pressure Liquid Chromatography Standard. We concluded that the methanolic extract of Ginger expressed antimicrobial potential against the above-mentioned bacteria. So Ginger can be safely used as a conventional medicinal source against bacteria.
