ABSTRACT
Objective:
To establish an HPLC method for the determination of genistein in genistein-loaded Eudragit nanoparticles.Methods:
The HPLC analysis was carried out on a DiamonsilTM C18(250 mm ×4.6 mm,5μm)column with the mobile phase of meth-anol-water (85∶15) at the flow rate of 1. 0 ml·min-1 . The detection wavelength was set at 261nm and the column temperature was 25℃.Results:
A good separation was displayed between the drug peak and the excipient peaks. An excellent linearity range for genistein was obtained from 1.0 μg·ml-1 to 100.0 μg·ml-1(r =0.999 8). The recovery of genistein was 99.85%(RSD =0. 65%,n=9).Conclusion:
The method is simple, rapid, accurate and specific, which is suitable for the determination of content and encapsulation efficiency of genistein-loaded nanoparticles.
