Abstract:
ABSTRACT OBJECTIVE：To establish a method for simultaneous determination of 8 components in the lyophilized product of Chaihu shugan san decoction. METHODS：UPLC method was adopted to determine the contents of albiflorin，paeoniflorin，ferulic acid，naringin，hesperidin，benzoyl paeoniflorin，glycyrrhizic acid and α-cyperone in 6 batches of lyophilized product of Chaihu shugan san decoction. The determination was performed on Phenomenex column with mobile phase consisted of 0.1％ formic acid water-acetonitrile at the flow rate of 1 mL/min，the sample volume was 10 μL. The detection wavelength was set at 250 nm，and column temperature was 30 ℃. RESULTS：The linear range of albiflorin，paeoniflorin，ferulic acid，naringin，hesperidin，benzoyl paeoniflorin，glycyrrhizic acid and α-cyperone were 3.606-8.414，23.988-55.972，1.218-2.842，35.964-83.916，12.009-28.021， 1.194-2.786，3.609-8.421，5.294-12.352 μg/mL，respectively（r＝0.999 5-0.999 9）. The limits of quantitation were 0.206，0.178， 0.256，0.168，0.196，0.242，0.268，0.157 μg/mL，respectively. RSDs of precision，stability（12 h）and repeatability tests were all lower than 2％（n＝5 or 6）；the recoveries were 97.93％，98.18％，96.57％，97.61％，98.51％，97.45％，98.14％，96.91％（all RSD＜2％ ）. The average contents of albiflorin， paeoniflorin， ferulic acid， naringin， hesperidin， benzoyl guanosine， and glycyrrhizic acid in 6 batches of samples were 59.258，429.237，23.173，625.847，200.424，15.048，67.620 μg/g，respectively. α-cyperone was not detected because of its volatility. CONCLUSIONS：The method is simple，stable，reliable and accurate. It could provide reference for quality control of the lyophilized product of Chaihu shugan san decoction
