Abstract:

 

Health beneficial effect of pomegranate is mainly due to   its confirmed high antioxidant capacity and polyphenolic content. In recent   years, experimental and clinical studies have shown that pomegranate intake   lowers blood pressure. Potassium and other minerals such as calcium and   magnesium may be responsible for this property. In this study, a rapid,   economic, reliable, and applicable capillary electrophoresis method was   proposed with contactless conductivity detection for the quantitative   determination of six cations in different pomegranate juices. The   correlation between these cation contents of eight different pomegranate   juices was evaluated by using one-way ANOVA and Duncan's multiple-range   test. The optimum buffer composition was selected as 20 mM 3-(N-morpholino)   propanesulfonic acid (MOPS) and 2.5 mM 18-crown-6 at pH 7.5. The proposed   method was validated for NH+44+_{4}^{+}, K++^{+}, Ca2+2+^{2+}, Mg2+2+^{2+},   Na++^{+}, Li++^{+} ions. These cations were quantified in different freshly   squeezed and commercial pomegranate juices with recovery values between   94.1% and 103.1%. Potassium was found as the predominant mineral,   reaching up to 2380 mg/L.
