Studies on content determination of polysaccharides in Periploca forrestii / 中国中药杂志

ABSTRACT

<p><b>OBJECTIVE</b>To establish a method for content determination of polysaccharides in Periplocaforrestii.</p><p><b>METHOD</b>The conversion coefficient of P. forrestii. polysaccharide to glucose was obtained by refined polysaccharides, and then the content of crude polysaccharides was determined by sulfuric-phenol method.</p><p><b>RESULT</b>The content of crude polysaccharides in P. forrestii. was 54.68% (RSD 3.0%, n = 6), and the average recovery was 101.7% (RSD 6.0%, n =6).</p><p><b>CONCLUSION</b>The method was simple, rapid, and accurate.</p>
