【 摘 要 】

The aim of this work was to develop and validate an analytical method for the quantification of tioconazole in polymeric nanocapsule suspensions by high performance liquid chromatography with UV detection. The analysis was performed with a mobile phase composed of methanol:water (80:20) and 0.18% ammonium hydroxide; RP-18 column and UV detection at 219 nm. The method proved to be linear in the concentration range of 5-50 µg mL-1 (r = 0.9999), specific, precise (repeatability RSD = 1.42%, intermediate precision RSD = 1.17%), accurate (98 - 102%) and robust (RSD < 2.0%). In conclusion, a simple and rapid method was validated proving suitable for quantification of tioconazole in polymeric nanocapsules.
