Abstract

A simple LC/UV method for the simultaneous identification and quantification of Fluoxetine, Tiratricol, Benfluorex and Pseudoephedrine in slimming formulation is proposed. The method demonstrated effective in the analyses of herbal mixtures marketed in Italy as slimming capsules. Sixteen different herbal mixtures, selected among the most frequently compounded in Italian pharmacies, were tested as matrices. HPLC analyses were performed in a gradient mode on a C18 stationary phase The method was validated for accuracy, precision, linearity and selectivity. The limits of detection (LOD) were 3.4μg/mL for Pseudoephedrine, 1.1μg/mL for Triac, 0.9μg/mL for Fluoxetine, and 0.8μg/mL for Benfluorex. Repeatability and intermediate precision, expressed as percent of relative standard deviation, ranged from 3 to 7 and from 7 to 12, respectively. Given these limits, the developed method is proposed for the simple and cost effective screening of herbal products illegally adulterated with these four drugs known to enhance slimming effects.
