Abstract: ABSTRACT AN HPLC METHOD FOR THE IN-VITRO QUANTIFICATION OF NOBILETIN The present invention relates to a reverse-phase high-performance liquid chromatography (RP-HPLC) method for the in-vitro quantification of Nobiletin as a single analyte, in isocratic elution mode, using a mobile phase comprising acetonitrile and 0.1% orthophosphoric acid in a ratio of 75:25 (v/v). The developed method exhibits a retention time of less than 10 minutes and has been validated for linearity, accuracy, precision, sensitivity, robustness and selectivity as per ICH Q2(R1) guidelines, while also demonstrating a favourable green analytical chemistry profile ABSTRACT AN HPLC METHOD FOR THE IN-VITRO QUANTIFICATION OF NOBILETIN The present invention relates to a reverse-phase high- performance liquid chromatography (RP-HPLC) method for the in-vitro quantification of Nobiletin as a single analyte, in isocratic elution mode, using a mobile phase comprising acetonitrile and 0.1% orthophosphoric acid in a ratio of 75:25 (v/v).
