Objective:To establish a method for the determination of jasminoidin and paeoniflorin in Qiyitang Granules.Methods:The analytical column was a Agilent Eclipse XDB-C18 column(4.5×150mm
5μm).The mobile phase consisted of acetonitrile-0.1%H3PO4(12:88
V/V)
flow rate was 1.0ml/min.The detection wavelength was 230 nm.Rusults:Jasminoidin and paeoniflorin were separated utterly and the linear correlation was good. The average recoveries of high
middle and low concentration of jasminoidin were 106.2%
97.5% and 98.1% respectively with RSD of 0.96%
1.23% and 1.62%(n=3)respectively.The average recoveries from paeoniflorin were 101.3%
99.5% and 98.2% respectively with RSD being 1.19%
1.33% and 1.58%(n=3)
respectively. Conclusions:The method is simple
reproducible
accurate and reliable.It may be used for the quality control of this granules.
