Table 2 Linear regression equations for dieckol in phlorotannin preparationsa

From: Method development and validation for dieckol in the standardization of phlorotannin preparations

Parameters Regression equationsb
Concentration (μg/mL) 12.5–400
Slope 34.575 32.992 34.864
Intercept 30.112 1.297 −24.646
Correlation coefficient (R 2) 0.9994 1.000 0.9999
  1. aValues were calculated using linearity analyses (n = 3)
  2. bRegression equation is Y = Ax + B, where Y is the peak area and x is the dieckol concentration (μg/mL)
