Table 2 Summary of statistical parameters and polynomial equation

From: Quality assessment and Analytical Quality by Design-based RP-HPLC method development for quantification of Piperine in Piper nigrum L.

Response P value Model significance Polynomial equation
Piperine
R1 0.0376 Significant + 1.39 + 0.1250 * X1 − 0.0450 * X2
R2 0.0355 Significant + 0.5225 + 0.0625 * X1 − 0.0325 * X2
  1. X1 and X2 are independent variables where, X1—conc. of acetic acid in aqueous phase and X2—mobile phase ratio
