High performance liquid chromatographic determination of aclacinomycin a and its related compounds. II. Reverse phase HPLC determination of aclacinomycin A and its metabolites in biological fluids using fluorescence detection.

A sensitive, simple and selective reverse phase high performance liquid chromatographic method was applied to the determination of aclacinomycin A (ACM) and its metabolites in plasma. The chromatography was performed on a microparticulate phenethyl derivative of silica using a mobile phase of acetonitrile-0.03 M ammonium formate buffer (pH 5.0), (50:50, v/v) and monitoring with fluorescence detector (excitation 435 nm-emission 505 nm). High reproducibility and linear calibration curves were obtained from 20 ng/ml to 100 ng/ml of ACM and its metabolites in plasma by use of internal standard methods.
