| Abstract: |
| Objective: To establish a method for the determination of orientin and isorientin in Danzhuye granule. Methods: The HPLC system consisted of the FORTIS-C18 (4.6 mm×250 mm, 5 μm) column, the mobile phase consisted of acetonitrile and 0.2% H3PO4 gradient elution flow rate was 1.0 mL/min, the column temperature was 30 ℃, the UV detector was set at 330 nm. Results: The linear response ranges were 3.08~61.50 μg/mL and 2.18~43.60 μg/mL (r=0.999 9). The average recovery of orientin and isorientin were 99.1% and 98.6%, RSD were 0.94% and 0.90% respectively. Conclusion: The method is rapid, simple, reproducible and specific. It can be an important method to control the standard of Danzhuye granule. |
