Optimization of extraction process of Chrysanthemi Flos by multi-index orthogonal experiment / 中国中药杂志

ABSTRACT

<p><b>OBJECTIVE</b>To explore quantitative assessment indicators of Chrysanthemi Flos, and optimize the extraction process of Chrysanthemi Flos through orthogonal experimental design.</p><p><b>METHOD</b>The concentration of ethanol, amount of ethanol, extraction time and extraction frequency were selected as factors in the L9 (3(4)) orthogonal experiment. A comprehensive assessment was conducted with the peak area of the eight major common peaks in the fingerprint of Chrysanthemi Flos as the indicators.</p><p><b>RESULT</b>The optimum extraction process was selected as follows using ultrasonic extraction method, adding 30-fold ethanol with 80% concentration, extracting for 2 times for extraction, 40 min for each time.</p><p><b>CONCLUSION</b>The optimized extraction process is reliable, with controllable assessment indicators, which is significant to the standardization of the extraction process and quality control of Chrysanthemi Flos preparations.</p>
