Abstract
Curcumin (Diferuloylmethane) is a natural product extracted from the root of Curcuma longa. 5-Bis (4-hydroxy-3-methoxybenzylidene)-N-methyl-4-piperidone, the piperidone analogue of curcumin (PAC), was one of the analogues that, demonstrated potential anticancer effects against breast and colon cancers compared with native curcumin. A simple, accurate, and rapid isocratic reverse phase high performance liquid chromatography (HPLC) analytical method utilizing UV detection was developed and validated for the determination of PAC utilizing C
column with run time was 7 min. Chromatogram showed a peak of PAC at retention time of 5.8±0.92 min. The method was validated for linearity, accuracy, precision, limit of detection, limit of quantitation and robustness. Linear relationship (r > 0.99) was observed between AUP of PAC and the corresponding concentrations over 100-10000μg/mL. The LOQ of this assay was 3.9ng/mL with a corresponding relative standard deviation of 4.8 and 4.0%. The LOD was 13.1ng/mL at a signal-to-noise ratio of >3.
