Study on TLC and Content Determination for Flowe rs of Fritillaria Thunbergii Miq
摘要
Abstract
To establish the quality standard for flowers of Fritillaria thunbergii Miq.Methods:Flowers of Fritillaria thunbergii Miq.were identified by TLC .The contents of peimine and peiminninne were determined by ELSD-HPLC:The optimal conditions of separation and detection were achieved on a C18 ana-lytical column with an mobile phase consisting of acetonitrile -water -triethylamine ( 68∶32∶0 .03 ) at the flow-rate of 1.0 mL/min;the temperature for the detector drift tube was set at 90℃and the nitrogen flow-rate was at 2.2L/min, 20μL as the injection volume .Results:The identification by TLC was highly specific . The calibration curves for peimine and peiminine were linear over the range of 0 .0185~0 .185 mg/mL (r=0.9998 ) and 0.0188~0.188 mg/mL(r=0.9997) , respectively .The average recovery rate was 100.40%with RSD of 1.50%(n=6).Conclusion:The method is simple and reproducible . It can serve as a quantita-tive determination and quality control of flowers of Fritillaria thunbergii Miq.关键词
