Abstract
A sensitive and precise HPLC procedure has been developed for the assay of amphotericin B in bulk samples and pharmaceutical formulations by using a C18 column [Kromosil, C18, (5 µm, 4.6mm x 250 mm; Make. Waters)], and mobile phase combination is 1% formic acid in water and acetonitrile in ratio of 45:55 V/V. The procedure has been validated as per the ICH guidelines. The λmax of detection was fixed at 407 nm, so that there was less interference from mobile phase with highest sensitivity according to UV analysis. Calibration plots were linear in the range of 10-100 µg/mL and the LOD and LOQ were 0.02 µg/mL and 0.06 µg/mL respectively. The high recovery and low relative standard deviation confirm the suitability of the method for routine quality control determination of amphotericin B in different formulations.
