Scopolamine solid phase extraction

The application of MIPs as the stationary phase in solid-phase extraction (SPE), often referred to as molecularly imprinted polymer solid-phase extraction (MIS P E), is a rapidly growing area [197-199]. With MISPE, highly specific enrichment of substances present at trace levels is possible. The technique has been applied to the analysis of drugs, for example, caffeine [200], scopolamine [201], naproxen [202], tetracycline [203], cholesterol [204] and local anesthetics [205], as well as environmental pollutants, exemplified by organophosphate flame retardants [206-208], triazines in soil and vegetable samples [71] and naphthalene sulfonates in river water [209]. [Pg.35]

Figure 4 Elution patterns of hyoscine (scopolamine) and its dehydrated metabolite, apohyoscine, from Cis SPE columns. Hyoscine (A) or apohyoscine (B) eluted with 40% (v/v) methanoliwater and hyoscine (C) or apohyoscine (D) eluted with 50% (v/v) metha-noliwater. The latter eluent was chosen for the assay as >90% of hyoscine was recovered in the first milliliter, whereas <5% of the apohyoscine was eluted in this volume. Washing with 20% (v/v) methanol removed the majority of the urinary pigments but not the hyoscine.
