Abstract:
Objective:To establish a RP-HPLC method with pre-column derivation for determining the content of stilbene glyco-sides in Yening granules. Methods:DNS-Cl was used as the derivation reagent, a Wondasil-C8 column (250 mm × 4. 6 mm, 5 μm) was used as the stationary phase and 30mM ammonium phosphatere gulation (pH 3. 5)-acetonitrile (78∶22) was applied as the mobile phase, a fluorescence detector (λex=370 nm,λem=560 nm) was used, the flow rate was 1. 0 ml·ml-1 , the column temperature was 30℃ and the injection volume was 20 μl. Results: There was no interference from the other substances in the preparation. The linear range of the two stilbene glycosides was 0.071-27.280 mg·ml-1(r=0.999 9). The average recovery was 99.04%(RSD=0. 1%, n= 9). Conclusion:The method is simple, quick, sensitive and accurate, which can be used for the quality control of Ye-ning granules.
