      Development of a high-performance thin-layer chromatography method for the quantification of alkyl glycerolipids and alkenyl glycerolipids from shark and chimera oils and tissues
      M. PAPIN, C. GUIMARAES, B. PIERRE-AUE, D. FONTAINE, J. PARDESSUS, H. COUTHON, G. FROMONT, K. MAHÉO, A. CHANTÔME, C. VANDIER*, M. PINAULT (*Nutrition, Growth and Cancer INSERM UMR 1069, University of Tours, Tours, France;

      Marine Drugs 20(4), 270 (2022). Samples were ether glycerols (EG) purified: (A) from Chimaera monstrosa liver oil (Chimaeridae); (B) from mixed liver oil of sharks Centrophorus squamosus (Centrophoridae) and Somniosus microcephalus (Somniosidae); (C) from Macaca fascicularis hearts (Cercopithecidae); (D) from tumors obtained by grafting in mice the human melanoma cell line MDA-MB-435s, and (E) from periprostatic adipose tissue of men with prostate cancer. Reduction of (phospho)ester glycerolipids into EG and fatty alcohols was part of the purification process. Octadecyl-glycerol and octadecenyl-glycerol were used as standards of alkyl- and alkenyl-glycerols, respectively. HPTLC on silica gel previously developed with chloroform – methanol 1:1, air-dried and activated for 30 min at 110° C. Application under nitrogen stream (6 bar). Development with petroleum ether – diethyl ether – acetic acid 60:140:1. After 2 h drying at room temperature under ventilation hood, visualization by 50 s immersing into sulfuric acid (7 % in ethanol), followed by 2 h drying under air-stream, and 14 min heating at 140° C. Plates were documented under white light illumination and densitometry was performed by computered scanning of the pictures. Alkyl-glycerols (mean hRF 34, LOQ 1235 ng/band) and alkenyl-glycerols (mean hRF 44, LOQ 2352 ng/band), present in all samples (except alkenyl-glycerols in shark oil), were quantified after method validation for specificity, sensitivity, accuracy, precision and repeatability. Linearity range was 1000 ng – 7000 ng for both EG types. To confirm the band identification, samples and standards were also submitted to acidic hydrolysis before HPTLC application. In this case, the bands of alkenyl glycerols did not appear, because chlorhydric acid reacted with the vinyl ether bonds to form glycerol and aldehydes.

      Globotriaosylceramide-related biomarkers of Fabry disease identified in plasma by high-performance thin-layer chromatography – densitometry – mass spectrometry
      C. JARNE, L. MEMBRADO, M. SAVIRÓN, J. VELA, J. ORDUNA, R. GARRIGA, J. GALBÁN, V. L. CEBOLLA* (*Institute of Carbon Chemistry, Spanish National Research Council (CSIC), Saragossa, Spain;

      J Chromatogr A 1638, 461895 (2021). Samples were sphingolipid-rich fractions of unproteinated blood plasma from healthy humans or from Fabry’s disease patients, as well as standards of sphingomyelin (SM) and of globotriaosylceramides (Gb3 = ceramide trihexosides), and related compounds (lyso-ceramide trihexosides, lactosyl ceramide, glucosyl ceramide). HPTLC on silica gel (Lichrosphere with spherical particles) by automated multiple development with a 9-step gradient, starting with pure methanol and ending with dichloromethane – methanol 9:1. Visualization and densitometry under UV 190 nm. Derivatization for Gb3 and derivatives (but not for SM) by immersion into orcinol solution (0.2 %, with sulfuric acid 10 %), followed by 15 min heating at 100 °C and by densitometry under visible light 550 nm. Bands of interest were directly eluted with methanol from underivatized plates into an ion-trap MS, through the oval head of a TLC-MS interface (with stainless steel frit to remove silica gel particles). Two different ionization processes were used: (A) electrospray ionization (ESI, capillary voltage 4 kV, endplate offset voltage -0.5 kV, nebulizer pressure 40 psi, drying gas 9 mL/min at 350 °C); (B) atmospheric pressure chemical ionization (APCI, capillary voltage 2–3 kV, current intensity 4.5 µA, nebulizer pressure 45 psi, drying gas 5 mL/min at 350 °C; vaporization at 450 °C). Full MS spectra were recorded up to m/z 1500 in positive ion mode. The relative ion intensities were used to quantify the detected species. Previous to this study, the precision of the elution head positioning was tested on Gb3 standard zones, comparing 3 positions for analyte elution: from the centre and from each higher or lower side of the band. The same main m/z peaks were observed in the 3 positions, but in different proportions. This was explained by the presence of coeluting Gb3 subclasses (the ceramide moiety CM being either saturated, mono-unsaturated fatty acyl with a slightly higher migration distance, or polar hydroxyl fatty acyl with the opposite effect on migration) and of coeluting Gb3 isoforms (the hexoside moiety consisting of glucose and/or galactose units). This resulted in the broadening and partial splitting of the standard band. In the plasma samples, 19 molecular species of Gb3 were identified (depending on the CM, the sugar isoforms being undistinguishable by MS): 5 with a saturated CM, 7 with two additional double bonds on the CM, 7 with a methylated CM. In case of Fabry’s disease, most Gb3 species with saturated CM were highly increased, whereas other species were decreased.

      D. ROJAS, M. VENCES, C. SOHLENKAMP, G. SANTOYO* (*Institute of Chemistry and Biology Research, University of MIchoacan San Nicolas de Hidalgo, Morelia, Michoacan, Mexico,

      Microbiol. Res. 268, 127295 (2023). HPTLC of cardiolipin phospholipids in the deletion mutants of two cardiolipin synthetase genes, clsA (UM270 ΔclsA) and clsB (UM270 ΔclsB), in the rhizobacterium Pseudomonas fluorescens, on silica gel with chloroform - methanol - water 14:6:1 for the first dimension and chloroform - methanol - glacial acetic acid 13:5:2 for the second dimension. The lipid composition of UM270 wt, UM270 ΔclsA and UM270 ΔclsB mutant strains was determined by labeling with [1-14C] acetate. Detection by iodine staining and radioactive membrane lipids were visualized by exposure to autoradiography film or a Phosphor Imager screen. Individual lipids were quantified using an image software.
