title: [ILs-HPLC simultanesous determination of five alkaloids in phellodenddri chinensis cortex].
abstract: A RP-HPLC method was established for simultaneous determination of phellodendrine hydrochloride (PH1), magnoflorine hydrochloride (MH), jatrorrhizine hydrochloride (JH), palmatine hydrochloride (PH2) and berberine hydrochloride (BH) in Phellodendri Chinensis Cortex by using ionic liquids as mobile phase additives. The separation was performed on a Kromasil C18 (4.6 mm x 250 mm, 5 μm) coupled with ultraviolet (UV) detection. The effect of extraction solvent, detection wavelength, length of alkyl chain on different imidazolium ionic liquids and concentration of ionic liquids on the separation and determination of alkaloids were investigated. Ionic liquid, [BMIm] BF4, can obviously improve the resolution and peak shape. This ILs-HPLC method is simple, rapid, and reliable, which can be used for determination of alkaloids in Phellodenddri Chinensis Cortex.
