摘要： A new methodis described for the simultaneous determination of methyl , ethyl,n-propyl and n-butyl p-hydroxybenzoates(parabens)in cosmetics by HPLC. The method is simple, effective and accurate. After parabens are extracted with ethyl alcohol,the clear ethyl alcohol solution is passed through a neutral alununum oxide column to remove co-extracted lipids and pigments. Parabens are determined by reverse-phase HPLC at 254nm.
