A rapid and moderately precise technique to measure partition coefficients of UV-absorbing solutes in solvent systems for countercurrent chromatog. is described and applied to p-nitrophenol and its conjugates with glucose, H2SO4 and glucuronic acid. It involves equilibration of 1 mL of each phase with solute in a narrow test tube, removal of the entire lower phase, dilution with MeOH and calculation of the partition coefficient as the ratio of the absorbance values of each dilution at any suitable wavelength. The polar conjugates of p-nitrophenol can be separated by countercurrent chromatog. by using EtOAc as mobile phase and aqueous KH2PO4 as stationary phase.
