Title

DETECTING NARCOTICS IN SOLUTION EXTRACTED FROM DRIED URINE STAIN ON THE COTTON FABRICS

Pages

  103-108

Abstract

 Introduction: Since URINE STAINs found on CRIME SCENEs are one of the crucial types of evidence in finding and detecting NARCOTICS, the present study accordingly aims to introduce a new method for detection of trace narcotic elements in the solution extracted from dried URINE STAIN left on cotton fabrics.Method: The present study was conducted in 2009 at the reference laboratory of the Legal Medicine Department of Markazi province in Iran. Narcotic substances were traced in the 50 samples, which had positive result in screening test, through two methods. In the first method, samples were directly examined through THIN LAYER CHROMATOGRAPHY (TLC). In the second method, a piece of cotton fabric measuring 30*30 cm was soaked in a beaker filled with 7 cc of urine sample and the solution was completely absorbed by the fabric. The piece of fabric was then let to dry at a temperature of 15-20oC. Once dried, it was soaked in 10 cc of distilled water and shaken for 30 minutes with a shaker so that the stain deposits would dissolve into water. Finally, the solution was extracted from the wet fabric in a five-minute 1000 rpm centrifugal spin and admixed with an equal amount of distilled water. A TLC test was run afterward.Findings: TLC on the main samples showed the followings: morphine, codeine and other opium alkaloids were detected in 38 samples while in 7 samples only codeine was found. In five samples no especial stain on TLC plate was found. The TLC performed on the solution tapped from the cotton piece of fabric showed similar results except for the lower density of stain colors.Conclusion: The results show that NARCOTICS may be detected in dried URINE STAINs on cotton fabric dissolved in distilled water. Further studies are encouraged to be designed to receive a standard protocol in wich the amount of required distilled water, based on the material of the fabric and the diameter of the URINE STAIN, would be specified, Consequently, URINE STAINs left on patients' fabrics or any piece of fabric left on the CRIME SCENE would be detected.
