Hair analysis is used in some branches of alternative medicine as a method of investigation to assist diagnosis. It is very useful when a history of drug use is difficult or impossible to obtain. In this re-search suspended droplet liquid phase microextraction (SDLME) coupled with high-performance liquid chromatography and photodiode array detection (HPLC-DAD) was used for preconcentration and analysis of scopolamine in hair samples. Therefore scopolamine was extracted from 2.0 g hair sample incubated in methanol (5 h, 50°C) and adjusted to pH 7.4 with, Na<sub>2</sub>HPO<sub>4</sub>–H<sub>3</sub>PO<sub>4</sub> buffer solution (donor phase, P<sub>1</sub>) into an organic phase (P2) 350 µl n-octanol and then back extracted into a micro drop of aqueous acceptor phase (P3), adjusted at pH 3, with HCL. The extraction time, T<sub>1</sub> (from P<sub>1</sub> to P<sub>2</sub>) was 2 min and T<sub>2</sub> (from P<sub>2</sub> to P3) was 30 min. Optimum instrumental conditions were included; A C<sub>18</sub> reverse phase column with water-acetonitrile-methanol (80:10:10) as the mobile phase was used and wavelength for UV detec-tion was 205 nm. The linear range was 10 to 10000 ng●mL<sup>–1</sup>, enrichment factor, detec-tion limit and relative standard deviation were 77, 0.1 ng●mL<sup>–1</sup> and 5.4 respectively.
