Abstract:

A method was developed for simultaneous determination of 10 spiked chemical drugs in antihypertensive herb preparations and health foods by microemulsion liquid chromatography (MELC). The nature and mass fraction of microemulsion components (surfactant, co-surfactant, and oil phase), the pH of microemulsion, and the type of the stationary-phase were investigated. Central composite design-response surface methodology was used. The optimized conditions for the separation of the 10 spiked chemical drugs were as follows:an Agela Promosil C18(2) column (250 mm×4.6 mm, 5 μm) was used at 30℃, and the microemulsion mobile phase (pH 3.0) consisted of 5.6% (mass fraction) polyoxyethylene lauryl ether (Brij35), 0.17% (mass fraction) sodium dodecylsulfate (SDS), 5.1% (mass fraction) n-butanol, 0.46% (mass fraction) cyclohexane and water (pH 3.0). The method is efficient, sensitive and environment friendly.
