S. Griffin et al., Determination of octanol-water partition coefficient for terpenoids using reversed-phase high-performance liquid chromatography, J CHROMAT A, 864(2), 1999, pp. 221-228
Octanol-water partition coefficients (K-ow) for 57 terpenoids were measured
using a RP-HPLC method. Sample detection was achieved with standard UV and
refractive index detectors and required no special column treatment. Measu
red log K-ow values for the terpenoids ranged from 1.81 to 4.48 with a stan
dard error of between 0.03 and 0.08 over the entire range. Partition coeffi
cients determined by the RP-HPLC method were compared against shake flask,
atom/fragment contribution, fragment and atomistic methods. The HPLC values
were found to give the best correlation with shake flask results. Log K-ow
values calculated by the atom/fragment contribution method gave the best c
orrelation with the HPLC values when compared to fragment and atomistic met
