Objective: To establish an HPLC method for simultaneous detemination of albiflorin
paeoniflorin
naringin
neohesperidin and baicalin in Tangminlingwan. Method: The chromatographic method was carried out on an Aglient Zorbax SB-C18 column(4.6 mm×250 mm
5 μm) with acetonitrile-0.05% phosphoric acid solution as the mobile phase by gradient elution. The flow rate was 1 mL·min-1.The detection was set at the wavelength of 230 nm. The column temperature was at 30℃. Result: The linear ranges of albiflorin
paeoniflorin
naringin
neohesperidin and baicalin were 0.008-0.320
0.021-0.832
0.088-3.52
0.124-4.96 and 0.086-3.44 μg(r≥0.9999
n=7)
respectively. The average recoeries were 99.7%(RSD 2.0%)
