      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 19:1 in a horizontal chamber at room temperature.

      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
      S. ARIYANATHAN*, A. SARASWATHY, G. RAJAMANICKAM (*Centre for Advanced Research in Indian system of Medicine (CARISM) SASTRA University, Thanjavur 613402, India,

      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 4:1 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 %.
