Abstract
High-performance frontal analysis (HPFA) was used for protein binding study of perillyl alcohol (POH) enantiomers to human serum albumin (HSA). The analysis was performed on a Develosil 100-Diol-5 (10 cm × 4.6mm I.D.) column. Sodium phosphate solution (pH 7.4, ionic strength 0.17) was used as the mobile phase at a flow rate of 1 mL/min. UV wave-length was set at 205 nm. An injection volume of 600 μL was chosen to ensure the drug to be eluted as a trapezoidal peak with a plateau. Experimental data were fitted by Scatchard analysis. The binding constant (K) and binding affinity(nK) of POH enantiomers to HSA were: K = 5.20 × 106 (1/mol), nK = 1.74 × 10 4 (1/mol) for (S)-POH and K = 3.71 × 106 (1/mol), nK = 1.51 × 104 (1/mol) for (R)-POH, respectively.
