Antimicrobial Activity of Crude Extract from Pomelo Peel against Staphylococcus aureus

The antimicrobial of crude extract from pomelo peel on Staphylococcus aureas was investigated. Four organic solvents including 95% ethanol, dichlorometane, hexane and ethyl acetate, were used to extract the crude extract from pomelo peel. The antimicrobial activity of the crude extract was evaluated by detection of clear zone of inhibition. The experimental results showed that yield of yield of 95% ethanol, dichlorometane, hexane and ethyl acetate crude extract were 0.46, 0.57, 0.25, and 0.19%, respectively. Crude extract from pomelo peel can be used to inhibit Staphylococcus aureus. The clear zones of inhibition of 95% ethanol, dichlorometane, hexane and ethyl acetate crude extract were 7.88, 8.83, 7.88, and 7.54 mm, respectively.
