Abstract
The purpose of this study was to develop a rapid, sensitive, and precise RP-HPLC (Reverse-Phase High-Performance Liquid Chromatography) method for the estimation of asiaticoside (AC) using the analytical quality by design (AQbD) approach. Initially, important AQbD prerequisites like analytical target profile (ATP) and critical analytical attributes (CAAs), such as theoretical plates and tailing factor, were defined. The final chromatographic conditions for the analysis of AC consist of stationary phase {A COSMOSIL 5C18-MS-II packed column (250 mm × 4.6 mm i.d, 5 µm)}, mobile phase was Smix {Methanol and Acetonitrile (40:25)}, and Orthophosphoric acid buffer (0.025 % OPA) in the ratio of 65:35 v/v at a flow rate of 1.0 mL/min and detection wavelength was 205 nm. The diversity in CAAs with different inputs was explained using the Ishikawa fishbone diagram. Taguchi design was selected as the first screening design to choose the critical material attributes (CMAs) that influence the method development. Subsequently, for more systematic optimization of the chromatographic technique and evaluation of CAAs, central composite design (CCD) was employed. In conclusion, the findings of the present study validated the utility of AQbD in the systemic design of a liquid chromatographic method with fine sensitivity for AC estimation in pharmaceutical products.
