      Quantification of tetrahydrocannabinol in Cannabis sativa
      Melanie BROSZAT*, E. CENIVIVA (*CAMAG, Sonnenmattstr. 11, 4132Muttenz, Switzerland, melanie.broszat@camag.com)

      CBS 119 (2017) 14-15. HPTLC of Cannabis sativa and standards cannabidiol (CBD), tetrahydrocannabinol (THC), and cannabinol (CBN) on silica gel with n-heptane – diethyl ether – formic acid 75:25:0.3 with chamber saturation for 20 min to a migration distance of 70 mm. Detection by spraying with Fast Blue salt B reagent (250 mg o-dianisidine bis(diazotized) zinc double salt in 10 mL water, 25 mL methanol and 15 mL dichloromethane), evaluation under white light. Quantitative determination by absorbance measurement at 210 nm prior to derivatization (for cannabinoid acids 285 nm). For the screening of THC-free samples the limit test can be used. The EU limit of 0.2 % is easily detected with or without detection. The %RSD of the assay prior to derivatization is 1.5 % and after derivatization 2.1 %. The LOD is 10 ng/zone.

      E. SHAWKY*, S.M. SALLAM (*Dep. of Pharm., Fac. of Pharm., Alexandria Univ., Alexandria 21521, Egypt, shawkyeman@yahoo.com)

      J. Chromatogr. Sci. 55 (10), 1059-1065 (2017). Presentation of a new high-throughput method for the simultaneous analysis of isoflavones and soyasaponins in soy (Glycine max L.) products by HPTLC on silica gel with ethyl acetate – methanol – water – acetic acid 100:20:16:1. Detection by treatment with anisaldehyde sulfuric acid reagent. Quantitative determination by densitometric multi-wavelength scanning at UV 265 nm for genistin, daidzin and glycitin and at 650 nm for soyasaponins I and III. The correlation coefficient of the linear calibration curve was >0.994. Intra-day precision (%RSD) of substances in matrix was between 0.7-0.9 %, inter-day precision (%RSD) was between 1.2-1.8 %). The method was suitable for the determination of the studied analytes in soy-based infant formula and soybean products.

      Using high performance thin layer chromatography-densitometry to study the influence of the prion [RNQ+] and its determinant prion protein Rnq1 on yeast lipid profiles

      Separations 5, 1-11 (2018). HPTLC of lipid content in yeast (clonal prion-infected and prion-free cells) on silica gel with 1) petroleum ether – diethyl ether – glacial acetic acid 80:20:1 for free sterols, free fatty acids, and triacylglycerols, 2) hexane – petroleum ether – diethyl ether – glacial acetic acid 50:20:5:1 for steryl esters, methyl esters, and squalene and 3) chloroform – diethyl ether – acetic acid 130:50:9 for phospholipids (phosphatidylethanolamine, phosphatidylcholine, and phosphatidylinositol). Detection of neutral lipids by spraying with 5 % phosphomolybdic acid in ethanol, followed by heating at 120 °C for 30 min. Detection of phospholipids by spraying with 10 % cupric sulfate in 8 % phosphoric acid, followed by heating at 140 °C for 30 min. Evaluation at 370 nm (deuterium lamp) for phospholipids and at 610 nm (halogen-tungsten lamp) for neutral lipids. The hRf values for neutral lipids were 10 for cholesterol, 33 for oleic acid and 51 for triolein as well as 41 for methyl oleate, 56 for cholesteryl oleate and 77 for squalene. The hRf values of phospholipids were 21 for phosphatidylinositol, 27 for phosphatidylethanolamine and 48 for phosphatidylcholine. HPTLC demonstrated to be a powerful tool for revealing subtle changes in the physiology of yeast.
