Abstract:Objective: To develop a RP-HPLC method for determination of three glycosides in Swertia punicea. Method: Chromatographic column: Alltimal C18(4.6 mm×250 mm, 5 μm). Mobile phase: methanol-water (including 0.05% H3PO4), and gradient elution.Flow rate: 1 mL·min-1. Wavelength: 254 nm. Column temperture: 30 ℃. Result:The calibration curves of gentiopicroside, mangiferin and swertrianolin were in good linearity over the range of 31.3-281.7,
0.31-2.78, 0.55-4.91 μg, (r=0.999 6, 0.999 3, 0.999 5). The average recoveries were 103.36%, 101.42% and 97.39%, with RSD less then 3% (n=5). Conclusion: It is a simple and sensitive meathod in controlling the quality of S. punicea.
