Abstract

(Colocasia esculenta [L.] Schott) leaves containing 6-C-glikosilflavonoid and O-glikosilflavonoid, including schaftoside isoschaftoside, orientin, isovitexin, isoorientin, vitexin, luteolin 7- O -sophoroside, cellulose, and phenol. Other studies mentioned taro leaf content including saponins, terpenes, tannins, flavonoids and alkaloids is thought to have antibacterial activity. The purpose of this study was to determine the activity of the fraction of n-hexane, ethyl acetate fraction, the fraction of water and ethanol extracts of leaves of taro as an antibacterial against Escherichia coli ATCC 25922. Colocasia esculenta [L] schoot leaf powder was macerad with 96% ethanol. And then fractionated using a solvent n-hexane, ethyl acetate and water. Fraction of n-hexane, ethyl acetate, water and the ethanol extract were tested for antibacterial activity using dilution method, with a concentration of 40%; 20%; 10%; 5%; 2,5%; 1,25%; 0,625%; 0,313%; 0,156%, 0,0078% of the bacteria Escherichia coli ATCC 25922. The results showed that the fraction of n-hexane, ethyl acetate, water, and a Colocasia esculenta [L] schott leaf extract has antibacterial activity against Escherichia coli with a minimum kill concentration respectively - contributed 40%; 10%; 20%; and 20%. Ethyl acetate fraction of taro leaf has the most effective antibacterial activity than the fraction of n-hexane, water and ethanol extract. Keywords :. Colocasia esculenta [L.] Schoot, Escherichia coli ATCC 25922, antibacterial, fraction of n-hexane, ethyl acetate fraction, the fraction of water.
