Abstract: Objective To establish an HPLC quantitative method for the determination of cinnamaldehyde and glycyrrhizic acid in Qiwei Putao power simultaneously. Methods The chromatographic conditions include column C18(Agilent ZORBAX Eclipse SB-C18,4.6@150 mm,5 Lm),acetonitrile25% acetonitrile(include 3% glacialacetic acid)(27z73) as mobile phase.The flow rate was 1 ml/min and monitored at 250 nm. Results The retention time of cinnamaldehyde and glycyrrhizic acid was about 10.2 min and 20.7 min respectively.The resolution was more than 1.5.The regress equation for cinnamaldehyde was Y=0.083 05X-1.205,r=0.999 9,and the linear range was 19.40 ~242.5 μg /ml.glycyrrhizic acid was Y=0.142 0X +1.340,r=0.999 9,and the linear range was 12.48 ~156.0μg/ml.The average recovery of cinnamaldehyde and glycyrrhizic acid was 100.2% and 100.5%,RSD 1.5% and 1.9% respectively. Conclusion This method is simple,time-saving and accurate.It can be used for routine analysis of cinnamaldehyde and glycyrrhizic acid in Qiwei Putao power.
