      J. Liq. Chromatogr. Relat. Technol. 31, 1892-1902 (2008). HPTLC of hydrochlorothiazide, walsartan, kandesartan, and enalapril on silica gel after chamber saturation using ethyl acetate - tetrahydrofuran - acetic acid 16:4:1 (for kandesartan and walsartan present together with hydrochlorothiazide) and 1-butanol - acetic acid - water 12:3:5 (for enalapril and hydrochlorothiazide). Quantitative determination by absorbance measurement at 252 nm for walsartan and kandesartan, at 274 nm for hydrochlorothiazide and at 208 nm for enalapril. The method was of high sensitivity and specific to analyte constituents.

      TLC and GC-MS identification of glucose and maltose in Biomphalaria glabrata (Gastropoda), and use of Quantitative TLC to determine the Effect of Starvation on the amounts of these Carbohydrates
      D. CLINE, B. FRIED, J. SHERMA* (*Department of Chemistry, Lafayette College, Easton, PA 18042, USA)

      Acta Chromatographica 9, 79-86 (1999). HPTLC (TLC) of glucose, maltose, sucrose and trehalose on silica gel with acetonitrile - water 17:3 and ethyl acetate – acetic acid – methanol – water 12:3:3:2 for three times with chamber saturation; on amino plates with ethyl acetate – pyridine – water – acetic acid 12:6:2:1 and on cellulose plates with ethyl acetate – pyridine – water 2:1:2, both in a non-equilibrated chamber; on RP-18 with tetrahydrofuran – water 44:6 in a pre-equilibrated chamber. All plates were prewashed, e.g. by chromatography with dichloromethane - methanol 1:1. Detection by 4-aminobenzoic acid reagent, 1-naphthol–sulfuric acid reagent or aniline–DPA reagent, each followed by heating at 110 °C for 10 min. The combined results from comparison of hRf values for two different mobile phases on silica gel, on cellulose, amino phase and C18-bonded layers with diverse separation mechanisms, spiking experiments on silica gel, detection with selective reagents, and GC–MS analysis definitely proved the presence of maltose and glucose and the absence of trehalose in digestive gland–gonad complex and hemolymph samples from B. glabrata. Earlier papers reporting the presence of trehalose were undoubtedly in error.
