| Abstract: | Aim To establish HPLC method for the determination of paeonol in mingmu dihuang capsule. Method The separation and assay were performed on Hypersil BDS C 18 （5 μm ,4.6 mm× 250 mm）, methanol-water（60： 40） as mobilephase at a flow rate of 0.8 ml ·min^-1 and detec- 10.24 mg ·L^-1 （ r = 0. 9997 ）, the average recovery was 100.6% and RSD was 1.3%. Conclusion This method is simple, sensitive and reliable to be used in the determination of paeonol in mingmu dihuang capsule . |
