Title: Determination of ester preservative in jam using matrix solid phase dispersion-HPLC
Abstract: Matrix solid phase dispersion was used to treat the jam sample and the paraben preservatives(methylparaben,ethylparaben,propylparaben,butylparaben) in the jam sample was determined by liquid chromatography.Parameters such as the kind of dispersant,the weight ratio of dispersant and sample,the kind and volume of eluent were studied and optimized.The compound was quantified by external standard method.The linear range were 0.1~40 μg/mL,the correlation coefficient of four paraben preservatives were 0.9994,0.9998,0.9999,0.9999 respectively.The detection limits range were 0.1~0.8 μg/g.The average recovery were 97.2%,91.1%,82.8%,77.6% respectively.
