Abstract:The polysaccharides of Portulaca oleracea was extracted by ultrasonic method and determined by phe- nol-vitriolic colorimetry in 488 nm. The results showed that the content of polysaccharides of Portulaca oleracea was the highest when harvested from Dushan of Guizhou in September, which suggested that harvest time and origin of place were the crucial factors for polysaccharides of Portulaca oleracea.
Keywords:Portulaca oleracea  polysaceharide  phenol-vitriolic colorimetry
