Abstract
|
|
|
|
This study was performed to investigate the effect of Portulaca oleracea extract on the antioxidant and antimicrobial activities against Helicobacter pylori. The each solvent extracts prepared from Portulaca oleracea were investigated by measuring total phenolic compounds, electron donating ability, superoxide dismutase-like ability and thiobarbituric acid reactive substances The herb extractor extract yielded the highest content of total phenolic compounds(72.2 ㎎%). The electron donating abilities(EDA) of ethyl acetate and methanol extracts showed high antioxidant activity. The superoxide dismutase (SOD)-like abilities of ethyl acetate and petroleum ether extracts also showed some activity. The antioxidant activity of thiobarbituric acid reactive substances was not significant. The petroleum ether extract of Portulaca oleracea showed the highest antimicrobial activity at 10, 000 ppm concentration.
