Abstract


A reversed-phase high-performance liquid chromatographic (HPLC) method was developed and validated for the determination of encapsulation efficiency of zidovudine in nanoparticules. The method was carried out in isocratic mode using 0.040M sodium acetate: methanol: acetonitrile: glacial acetic acid (880:100:20:2) as mobile phase, a C8 column at 25ºC and UV detection at 240 nm. The method was linear (r2 ˃ 0.99) over the range of 25.0-150.0 μg/mL, precise (RSD ˂ 5%), accurate (recovery = 100.5%), robust and selective. The validated HPLC-UV method can be successfully applied to determine the rate of zidovudine in nanoparticules.
