      The effect of the diluent on the retention of steroidal compounds in liquid - solid chromatography
      S.M. PETROVIC*, M.M. ACANSKI, L.A. KOLAROV, E.S. LONCAR, (*Dept. of Anal. Chem., Fac. of Technology, Univ. of Novi Sad, Bul. Cara Lazara 1, P.O. Box 340, 21000 Novi Sad, Yugoslavia)

      J. Planar Chromatogr. 8, 200-204 (1995). Study of the retention behavior of a series of steroids in liquid - solid chromatography as a function of the concentration of the diluent in ternary nonaqueous mobile phases. The relationship between the retention constant RM and the concentration of a diluent in the mobile phase was linear, with the slope values depending on the molecular structures of the compounds.

Linearity was in the range of 30-400 ng/zone for (1), 50-300 ng/zone for (2) and 150-500 ng/zone (3). The intermediate precision was below 2 % (n=3) for (1) to (3). The LOD and LOQ were 9 and 27 ng/zone for (1), 13 and 39 ng/zone for (2) and 41 and 123 ng/zone for (3). Recoveries for (1) to (3) were in the range of 90-110 %. The method was statistically compared to a validated HPLC method.

Detection by spraying with freshly prepared p-anisaldehyde sulfuric acid reagent, followed by heating at 110 °C for 3 min. Quantitative determination by absorbance measurement at 530 and 540 nm. The hRf values for (1) to (3) were 64, 84 and 47, respectively. Linearity was in the range of 2-10 μg/zone for (1) to (3). The intermediate precision was below 0.6 %. The LOD and LOQ were 410 and 1270 ng/zone for (1), 550 and 1680 ng/zone for (2) and 300 and 920 ng/zone for (3), respectively. Average recovery for (1) to (3) was 99 %.

      TLC and GC - MS determination of cholesterol in consumable fats
      D. BODZEK*, W. BAKOWSKI, T. WIELKOSZYNSKI, B. JANOSZKA, B. JARENCZUK, R. TARNAWSKI, K. TYRPIEN, (*Silesian Med. Acad., Dept. of General Chem., Jordana str 19, 41 - 808 Zabrze, Poland)

      Acta Chromatographica 8, 122-143 (1998). TLC of sterols on silica gel, silica gel/Kieselguhr, aluminium oxide and RP-18 with e.g. acetone - chloroform 1:9 on silica gel. Chromatograms were developed in a DS-type sandwich chamber. OPLC was used to achieve optimum conditions for the separation of sterols. Visualization either by spraying with an ethanolic solution of phosphomolybdic acid or with the modified Lieberman-Buchard reagent. The separation of sterols was, however, only possible as a whole group because of the small structural differences between sterols(!). Rapid and simple method for the isolation of sterols.

Detection of 7-ketocholesterol under UV 254 nm.
