Phytochem. Anal. 20, 19-23 (2009). TLC of curcumin (1), demethoxycurcumin (2), and bisdemethoxycurcumin (3) from the rhizomes of Curcuma longa on silica gel with hexane – chloroform – methanol 10:10:1 as mobile phase. Quantitative determination by recording the chromatogram using a digital scanner and analyzing the density of the TLC spot with the Scion Image software. The hRf values of (1), (2), and (3) were 42, 25, and 18, respectively. Selectivity regarding matrix was given. Linearity was between 0.375 and 6 µg/spot for all curcuminoids. The intermediate precision of the method was satisfactory. Recovery was 101.9 % for (1), 104.8 % for (2), and 101.5 % for (3). The limits of detection and quantification were 43 and 143 ng/spot for (1), 69 and 230 ng/spot for (2), and 73 and 242 ng/spot for (3). The method was compared with an official densitometric method, and the analytical results were not significantly different.

TrAC 29, 209-224 (2010). The dangerous effects of cocaine on living organisms and current problems associated with its wide use and availability have led to the development of various analytical procedures. This review discusses analytical methods proposed during the past ten years for the verification of cocaine and its metabolites in biological samples. Challenges regarding sample preparation and extraction techniques are described. Different approaches using thin-layer chromatography are discussed, and especially the possibility of simultaneous determination of parent, metabolite and interfering drugs in urine samples, as well as the identification of markers for combined consumption of cocaine and alcohol.
