      Comparison of methods for calculation of the partition coefficients of selected aliphatic compounds
      Anna NIESTROJ (Silesian University, Institute of Chemistry, 9 Szkolna Street, 40-006 Katowice, Poland; annaniestroj@wp.pl)

      J. Planar Chromatogr. 23, 198-200 (2010). Proposition of new methods for calculation of the partition coefficients of aliphatic compounds from experimental Rf values and the numerical values of selected topological indexes. The experimental partition coefficient (log Pexp) of cetyl alcohol was determined for the n-octanol-water system. Numerical values obtained were compared with theoretical values from a database (AlogPs, AC_logP, AB/LogP, ALOGP, milogP, and XLOGP2). HPTLC of cetyl alcohol, stearyl alcohol, palmitic acid, stearic acid, alpha-hydroxypalmitic acid, and 12-hydroxystearic acid on RP18 with methanol and with methanol - water 191 in a horizontal chamber at room temperature. Detection after visualization in iodine vapor.

      Post-chromatographic fixed-charge derivatization for the analysis of hydroxyl-containing compounds by a combination of thin-layer chromatography and matrix-assisted laser desorption/ionization mass spectrometry
      C. ESPARZA, R.S. BORISOV*, N.YU. POLOVKOV, V.G. ZAIKIN (*A. V. Topchiev Inst. of Petrochem. Synth., Russian Acad. Sci., Leninskii pr. 29, Moscow, 119991, Russia)

      J. Chromatogr. A 1560, 97-103 (2018). Proposal of a simple and convenient on-spot derivatization approach for the modification of hydroxyl-containing compounds for their analysis by TLC/MALDI. Post-chromatographic acylation of separated analytes with 3-bromopropionyl chloride with simultaneous quaternization of pyridine, resulted in derivatives with permanent positive charges, which, in contrast to the initial alcohols not ionizable under TLC/MALDI conditions, reveal intense peaks of their cationic moieties in MALDI mass spectra recorded directly from TLC plates. Demonstration of the method by applying to a series of mammalian and plant sterols, phenols and terpene alcohols.

      Quality control standards for the roots of three plumbago species

      Ind. J. Pharma. Sci. 72(1), 86-91 (2010). Three species of Plumbago (Plumbaginaceae), i.e. P. zeylanica, P. carpensis, and P. rosea were studied for different physico-chemical parameters in addition to the estimation of microbial contamination, aflatoxins and pesticide residues and heavy metal content. All three species are used as herbs. The fingerprint profile of each species was compared using plumbagin as marker. Chloroform extracts of each plant were subjected to chromatography on silica gel with toluene - ethyl acetate 41 in a saturated twin trough chamber. Detection under UV 254 nm and 366 nm. The hRf value of plumbagin was 70. The identity of plumbagin in the samples was shown by overlay of the UV spectra. Linearity was between 200 and 1000 ng/zone. The amount of plumbagin in the three species was between 0.01 and 0.17 %.

      Planta Med. 83, 1011-1019 (2017). The subfractionation on silica gel column of a diethyl ether fraction of a hydromethanolic extract of Lamium album aerial parts was controlled by TLC on silica gel with ethyl acetate – formic acid – water 2023. Detection was performed at UV light after derivatization with 1 % Natural Product Reagent A. From the last subfraction, caffeic acid and tiliroside were isolated. The same TLC monitoring was applied for the fractionation of the butanol fraction of the extract. Some fractions and their subfractions were purified on dextran gel (Sephadex LH-20), and monitored by TLC on silica gel with ethyl acetate – formic acid – acetic acid – water 100111126, with the same detection. These subfractions contained caryoptoside and other iridoids, glucomartynoside, lamiusides and other phenylpropanoid derivatives.
