Pre-treatment in determining total polysaccharide in flos Chrysanthemum indicum by response surface design / 中国中药杂志

ABSTRACT

<p><b>OBJECTIVE</b>To study pre-treatment in determining total polysaccharide in flos Chrysanthemi Indici.</p><p><b>METHOD</b>The factors including the extraction temperature, extraction time, ratio of material to liquid were studied. The best extraction condition was found through the response surface design.</p><p><b>RESULT</b>The best extraction condition as follows 81.0 degrees C of the extraction temperature, 1.6 h of extraction time, and the ratio of material to water as 1 29. On these conditions the extraction rate of flos Chrysanthemi Indici was the best.</p><p><b>CONCLUSION</b>A model equation that can be used to predict the experiment is established through the response surface method.</p>
