ABSTRACT

Objective:

To establish a method for determination of forsythin in Shuanghuanglian Oral (Flos Lonicerae, Radix Scutellariae, Fructus Forsythiae, etc.)

Methods:

After processing by RP SPE (reverse phase solid phase extraction), the sample solution was measured by RP HPLC. The chromatographic conditions were Prodigy ODS (3) (150?4.6mm,5?m) column as analytic column; MeOH H 2O HAc(40∶60∶1,V/V) as mobile phase; detection wavelength at 227nm; column temperature at 35?C ; flow rate at 1.0mL?min -1 .

Results:

The linear range of forsythin was 0.1~2.0?g, r =0.9997. The average recovery was 102.2%, RSD =0.61%( n =6).

Conclusion:

The method is simple, accurate, reproducible and can be used to enhance the quality control of this drug.
