You can use two-phase system and vitamin B5 provitamin B5 and Cosmetics and oil-soluble surfactant composition is initially separated potassium ferrocyanide - co-precipitating agent to remove the zinc acetate extract macromolecules group quality. After pantothenic acid under acidic conditions and D- panthenol enriched in the solid phase extraction C18 stationary phase, the removal of other water-soluble interferences, with 40% A Alcohol aqueous solution elution reversed-phase high-performance liquid chromatography, UV detector or a tandem quadrupole mass spectrometry, a standard curve of external standard.
