title: [Retention behavior of statins in microemulsion liquid chromatography].
abstract: The effects of the concentration of surfactant, co-surfactant and lipophilic organic solvent and the pH value of mobile phase on the retention behavior of statins in microemulsion liquid chromatography have been investigated using pravastatin sodium, atorvastatin calcium, lovastatin and simvastatin as model compounds. The experimental results showed that the effects of the concentration of surfactant, co-surfactant and lipophilic organic solvent on the retention behavior of statins in microemulsion liquid chromatography were fully consistent with the theoretical modeling. The effect of the pH value of the mobile phase on the retention behavior of acid statins was fully consistent with the theoretical modeling. The relationship between the retention factor of neutral statins and the concentration of hydrogen ion was an implicit function. The retention modeling can reflect the effect of composition of microemulsion solution on the retention behavior of statins drugs.
