J. Liq. Chromatogr. Relat. Technol. 42, 1-8 (2019). HPTLC of phospholipids (phosphatidylcholines, phosphatidylethanolamines, cardiolipins and phosphatidylglycerols) associated to membrane proteins in Rhodobacter (Rb.) blasticus, Rhodospirillum (R.) rubrum and Rhodobaca (Rbc.) bogoriensis on silica gel with a 7-step gradient based on methanol - water - ethyl acetate. HPTLC was coupled to electrospray mass spectrometry (ESI-MS) using an elution head-based interface for the identification of several phospholipid species.
J. Liq. Chromatogr. Relat. Technol. 42, 249-257 (2019). HPTLC of methanolic extracts from the leaves of Paulownia tomentosa on silica gel with chloroform - ethyl acetate - methanol 20:3:2. HPTLC-direct bioautography by dipping into B. subtilis cell suspension, followed by incubation at 28 °C for 2 h. Then the bioautograms were dipped into an aqueous solution of the MTT vital dye (1 mg/mL (3-[4,5-dimethylthiazol-2-yl]-2,5-diphenyltetrazolium bromide), followed by incubation at 28 °C for 30 min. Further analysis by using a HPLC-DAD-MS system allowed the identification of apigenin and p-coumaric acid as highly abundant antibacterial components.
Planta Med. 83(17), 1321-1328 (2017). Benzoyl-aconine esters (lipo-alkaloids) produced by transesterification of aconitine (isolated from Aconitum sp.) with long-chain fatty acids were purified by a multistep chromatographic method, including cyclodextrane gel filtration chromatography, centrifugal planar chromatography on aluminium oxide layer using cyclohexane – chloroform – methanol 70:30:1 followed by 70:30:3 and/or preparative thin-layer chromatography on aluminium oxide layer with toluene – acetone – ethanol – concentrated ammonia 70:40:10:3.
J. Planar Chromatogr. 32, 243-249 (2019). HPTLC of stigmasterol (1) and cinnamic acid (2) in Pluchea dioscoridis on silica gel with chloroform - methanol - acetic acid 93:5:2. Quantitative determination of (1) by absorbance measurement at 254 nm. Compound (2) was detected by spraying with p-anisaldehyde and quantified under UV light at 513 nm. The hRF values for (1) and (2) were 57 and 19, respectivley. Linearity was between 200 and 1400 ng/zone for (1) and (2). The intermediate precision was below 2 % (n=6). The LOD and LOQ were 39 and 117 ng for (1) and 43 and 129 ng for (2), respectively. Recovery rate was between 98.8 and 99.4 % for (1) and 98.4 and 99.0 % for (2).
J. Planar Chromatogr. 32, 13-24 (2019). HPTLC of three omega-3 fatty acids, namely docosahexaenoic (1), eicosapentaenoic (2) and alpha-linolenic (3) on silica gel (activated by immersion in a 10 % silver nitrate solution in acetonitrile for 30 min, followed by drying at 60 °C for 30 min) with toluene - n-propanol - glacial acetic acid 200:20:1. Detection by exposure to iodine vapor for 60 min. Quantitative determination by absorbance measurement at 520 nm. The hRF values of (1) to (3) were 15, 26 and 57, respectively. The intermediate precision was below 2 % (n=10). The LOD and LOQ were 174 and 539 mg/mL for (1), 197 and 597 mg/mL for (2) and 201 and 609 mg/mL for (3), respectively. Average recovery for (1) to (3) was between 96.6 and 103.2 %.
J. Pharm. Biomed Anal. 45(2), 337-340 (2007). HPTLC of oleanolic acid and ursolic acid on silica gel impregnated with 1 % iodine solution in chloroform after sample application. Development with petroleum ether - ethyl acetate – acetone 82181. Detection by spraying with a solution of 10 % sulfuric acid in ethanol followed by heating at 120 °C for 3 min. Quantification by densitometry in absorbance mode at 530 nm.
J. Chromatogr. A 1515, 232-244 (2017). Characterization of lipids in both bone marrow (BM) and mineralized tissue (MT) compartments, and their potential implication in bone pathologies, involving sample preparation, lipid extraction and analytical issues using a small sample size (? 0.5 g of rat femurs). Two major issues in bone handling were addressed with two cleaning steps after BM removal and by adding a demineralization step to the overall lipid extraction protocol, to avoid potential contamination of the MT by marrow lipids and the poor accessibility of certain lipids from the MT. HPTLC of the major neutral and polar lipids provided excellent resolution for 15 standards, good precision (inter-day %RSD <13 %) and recoveries of the standards ranged between 76 and 122 %. The method was suitable for lipid determination in both BM and MT and reliable in terms of lipid quantification. Demineralization facilitates phosphatidylserine and cholesterol ester extractions from the MT. Confirmation of the HPTLC data by HPLC determination of fatty acids as naphthacyl esters in bone samples. The mineralized tissue seems to be more metabolically active than the bone marrow.
