| Abstract: | Objective: To extract polysaccharides from Portulaca oleracea and determine its content. Method: The polysaccharides of portulaca oleracea were obtained through hot water extraction and ethanol precipitation by microwave technique, which content was determined by phenol-vitriolic colorimetry. Result: The polysaccharides content of Portulaca oleracea was 8.94% , a average recovery was 98.52% with RSD = 1.28% ( n = 6). Conclusion: The polysaccharides extrated from Portulaca oleracea has been obtained by microwave technique applied first. |
