Objective To establish a method for the determination of total flavonoids, polysaccharides and inorganic salts in 16 batches of Huagan Decoction, and to establish a high performance liquid chromatog.(HPLC) method for the simultaneous determination of five active components in Huagan Decoction, which provides a comprehensive basis for the quality control of the classic recipe Huagan Decoction.Methods The contents of total flavonoids and polysaccharides in Huagan Decoction were determined by UV-visible spectrophotometry, and the methodol. was investigated.The content of inorganic salts was determined by ash determination method.The determination was performed on Kromasil 100-5-C18(250 mmx4.6 mm, 5 μm) column with mobile phase consisted of acetonitrile-0.05%phosphoric acid solution(gradient elution) at the flow rate of 0.9 mL/min.The column temperature was 30°C.The detection wavelength was 230 nm, and the methodol. was investigated.Results The average content of total flavonoids, polysaccharides and inorganic salts in the 16 batches of Huagan Decoction were about 2.99% ,13.92%, 8.55%; the linear ranges of hesperidin, D-glucose anhydrous were 0.0051-0.0306, 0.0103-0.0620 mg/mL; the average recoveries of total flavonoids and polysaccharides were 95.84% and 96.12%, with RSD of 1.86% and 1.97%, resp.The average content of gallic acid, geniposide, paeoniflorin, narirutin, hesperidin were about 0.56%, 1.94%, 2.37%, 0.22%, 0.89%; the linear ranges of them were 6.03-301.27, 20.63-773.72, 20.18-504.41, 5.95-297.53, 9.90-247.62 μg/mL; theaverage recoveries of them were 97.54%, 102.39%, 96.48%, 103.60%, 98.22%, with RSD of 1.72%, 1.41%, 1.38%, 1.21%, 0.97%, resp.Conclusion The established method for the content determination of totalflavones, polysaccharides, inorganic salts and five active components has good accuracy and repeatability, which can provide comprehensive basis for the quality control of Huagan Decoction.
