Antimicrobial activity of ethanolic extracts of Phoenix loureiroi Thorns

Abstract

Phoenix loureiroi is commonly known as ‘chittetha’ and the plant leaves are used for household purpose. Preliminary chemical studies of the plant reveal the presence of glycosides, tannins & flavonoids. The main objective of the study is to evaluate the antimicrobial activity of Phoenix loureiroi thorn extract on E. colli, Bacillus & Streptococcus. Both the aqueous and ethanolic extracts showed good activity against all the microorganisms used. The crude extracts at a dose of 500mg/ml showed potent activity against E. colli, Bacillus & Streptococcus. Ethanolic extract was found to be more potent when compared with aqueous extracts.
