A HPLC method for the simultaneous determination of seven anthracyclines.

A HPLC method has been developed for the determination of epirubicin hydrochloride, doxorubicin hydrochloride and idarubicin hydrochloride in the presence of four other anthracyclines. This method ensures the rapid determination of seven anthracyclines. It is simple and rapid and does not require any preliminary treatment of the sample.

Rapid HPLC method for the determination of paclitaxel in pharmaceutical forms without separation.

A HPLC method has been developed for the in-process determination of the paclitaxel from dosage pharmaceutical forms. This method ensures the rapid determination of paclitaxel in the presence of polyoxyl castor oil--the main constituent of paclitaxel's clinical formulation vehicle. The method is simple and rapid and does not require any preliminary treatment of the sample.

A HPLC validated assay of paclitaxel's related impurities in pharmaceutical forms containing Cremophor EL.

A HPLC method has been developed for the determination of the paclitaxel's related impurities in pharmaceutical forms. This method ensures the rapid determination of related impurities in the presence of polyoxyl castor oil--the main constituent of paclitaxel's clinical formulation vehicle. The method is simple and does not require any preliminary treatment of the sample.

Determination of the 5-fluorouracil and N1(2'-furanidyl)uracil in the presence of tegafur by zero-crossing first derivative spectrometry.

A first derivative spectrometric method has been developed for the determination of the 5-fluorouracil and N1(2'-furanidyl)uracil related substances and degradation products of tegafur. The wavelengths selected for the determination of 5-fluorouracil and N1(2'-furanidyl)uracil were 298 and 288 nm, respectively. At this wavelength, the calibration graphs between the amplitude of the signals and the concentration of each compound were linear up to 24.
