Quantitative determination by absorbance measurement at 240 nm. The hRf of compounds (1) and (2) were 30 and 48, respectively. Linearity was in the range of 200-1000 ng/zone. Limits of detection and quantification were found to be 13 and 22 ng/zone for (1) and 18 and 31 ng/zone for (2), respectively. Recovery was found to be 99.2-99.5 % for (1) and 98.9-99.2 % for (2), respectively. The method showed comparable results to a validated HPLC method.
