HPLC Measure the Content of Emodin in Raw and Prepared Fleece-flower Root

Yang Xianling Red Cross Taiwang Compatriot Hospital of Xiangshan County,Zhejiang Province(315731)  
[Objective]Make measurement of emodin content in raw and prepared fleece-flower root.[Method]Take HPLC and the color-spectrum column SPHERISORB ODS2(150×4.6mm,5μm),the flow spectrum being methanol –0.1% phosphate(85:15),the measurement wave length:254nm,column temperature:28℃,flow speed:1.0 ml·in-1.[Result]The regression equation Y=3352.3X+37.297,the linear range:0.03~0.20μg,the average reception rate of the raw fleece-flower root:96.6%(RSD=1.3%).[Conclusion]The said method is correct and quick,with good repeat,can be used for quality control of fleece-flower root drug.
