| Abstract: | The content of polysaccharides in astragalus membranaceus（fisch） was determined by phenol-sulfuric acid spectrophotometry with extracting of water and purifying of EtOH.The method had a good recovery of 94.81%—103.50% in range of 0.00—0.14mg/mL.The content of polysaccharides was 4.3%.The contents of trace elements,Fe,Zn,Cu and Mn were determined by air-acetylene flame atomic absorption spectrometry.There were the higher contents of these elements in astragalus membranaceus of HeiLongjiang. |
