      Nature - Lab. Invest. 100, 1411–1424 (2020). Samples were chloroform – methanol 1:1 solutions of lipid standards and of liver tissue extracts from wild-type mice (1), from transgenic murine models of hepatic steatosis (2) (mice expressing HBs, hepatitis B virus surface protein), or of cholestasis (3) (mice totally knock-out for the gene of phospholipid translocator ABCB4, ATP-binding cassette subfamily B member 4), or of both (4) (hybrids of mice (2) and (3)). HPTLC on silica gel (preheated at 110°C for 15 min) with n-hexane – diethyl ether – acetic acid 20:5:1. (A) For qualitative analysis, visualization under white light after immersion into anisaldehyde 0.5 % (in sulfuric acid – acetic acid – methanol, 1:2:17), followed by heating at 110°C for 9 min. (B) Identification of lipids was confirmed by elution of the zones of interest with methanol from the HPTLC layer through a TLC-MS interface and a filter frit directly to a quadrupole-orbitrap MS (atmospheric pressure chemical ionization, full HR-MS scan in m/z range 100–1000). (C) For quantitative analysis, visualization at UV 366 nm after derivatization by immersion into primuline reagent (primuline 0.5 g/L in acetone – water 4:1); fluorescence was measured at UV 366 nm (mercury lamp, optical filter for wavelengths above 400 nm, scanning slit 6.0 mm × 0.2 mm, speed 20 mm/s). (A) and (B) allowed the separation and detection of cholesterol, cholesteryl oleate, methyl oleate, free fatty acids (FFA, expressed as oleic acid equivalents) and triacylglycerols (TAG, as triolein equivalents) in liver extracts. (C) showed that TAG was decreased and FFA increased in (3) and (4), compared to (1) and (2). Cholesterol and cholesteryl oleate had no significant changes between groups.

      J. Liq. Chromatogr. Relat. Technol. 44, 148-170 (2021). Comprehensive review of the contribution of HPTLC to the analysis of lipids in the last ten years. Advances in detection, identification and determination of main classes of lipids and their subclasses separated by HPTLC in different matrices were discussed. The review described techniques for scanning densitometry of lipids through direct detection and on-plate staining using inorganic and organic agents, immunostaining of glycosphingolipids and labeled lipids. Techniques coupling HPTLC with mass spectrometry were also discussed, including extraction-based interfaces, ionization of lipids, on-plate matrix assisted laser desorption and ionization, and its application in the analysis of sphingolipids, neutral lipids and fatty acids and phospholipids.

      Carotenoid composition and antioxidant potential of Eucheuma denticulatum, Sargassum polycystum and Caulerpa lentillifera.
      V. BALASUBRAMANIAM*, L. JUNE CHELYN, S. VIMALA, M.N. MOHD FAIRULNIZAL, I.A. BROWNLEE, I. AMINE (*Nutrition, Metabolism & Cardiovascular Research Centre, Institute for Medical Research, Ministry of Health Malaysia, Shah Alam, Selangor, Malaysia;

      Heliyon 6(8), e04654 (2020). HPTLC of ethanolic extracts of three algae (100µg/band) on silica gel, along with carotenoid standards (10µg/band), developed with toluene – acetone 7:3. Detection under white light. Carotenoids appeared orange or yellow, chlorophylls green, pheophytins dark khaki. Carotenoid patterns of the algae were very different depending on the family: red alga Eucheuma denticulatum (Solieriaceae) contained mainly zeaxanthin and lutein (hRF 44) and β-carotene (hRF 88), but also β-cryptoxanthin (hRF 69-71) and fucoxanthin (hRF 39); brown alga Sargassum polycystum (Sargassaceae) contained mainly fucoxanthin, and also cryptoxanthin; green alga Caulerpa lentillifera (Caulerpaceae) contained mainly zeaxanthin, but also astaxanthin (hRF 61) and canthaxanthin (hRF 77) in smaller amounts. Separately, HPLC-MS was used to confirm and quantify these compounds, which was necessary for carotenoids with similar hRF values: zeaxanthin and lutein (hRF 44), and β-carotene and lycopene (hRF 88).
