J. Food Compos. Anal. 48, 25-33 (2016). In this study 353 samples of different varieties and different commercial products were analyzed by HPTLC and UV absorbance. HPTLC of the acetonic extract of kava powder on silica gel with hexane – dioxane 4:1 without chamber saturation over a distance of 85 mm. Detection under UV 254 nm and 366 nm. Densitometric evaluation and determination of the ratios kavain/total kavalactones (K/KL) at 254 nm and flavokavins/kavalactones (FK/KL) at 366 nm. Derivatization by dipping in anisaldehyde sulfuric acid reagent (10 mL sulfuric acid, 170 mL methanol, 20 mL acetic acid, 1 mL anisaldehyde) and heating at 100 °C for 3 min. The results showed that noble varieties suitable for daily consumption of kava are characterized by high K/KL and low FK/KL.
Trends Anal. Chem. 86, 25-38 (2017). Review of methodologies for the detection of adulterants in honey, including the application of HPTLC based on the fructose/glucose ratio and the sucrose content.
J. Ethnopharmacol. 195, 324-333 (2017). HPTLC of quercetin (1), kaempferol (2), beta-sitosterol (3) and luteolin (4) in fresh flowers of Saraca asoca on silica gel with toluene – acetone – formic acid 10:4:1 for (1), cyclohexane – ethyl acetate – methanol – formic acid 12:9:1:1 for (2), toluene – methanol 8:1 for (3) and toluene – ethyl acetate – formic acid 15:15:4 for (4). Quantitative determination by absorbance measurement at 378 nm for (1), 365 nm for (2), 366 nm for (3) and 254 nm for (4). The hRF values for (1) to (4) were 29, 35, 42 and 45 respectively.
Food Control. 70, 119-129 (2016). HPTLC of aflatoxins AFB1, AFB2, AFG1 and AFG2 in Brazil nut (Bertholletia excelsa) on silica gel with toluene – ethyl acetate – formic acid 5:4:1. Qualititative identification under UV light at 366 nm.
chromatographic method for simultaneous estimation of the active pharmaceutical ingredients metolazone and spironolactone
J. Planar Chromatogr. 29, 380-387 (2016). HPTLC of metolazone (1) and spironolactone (2) on silica gel with ethyl acetate ‒ chloroform ‒ glacial acetic acid 50:50:1. Quantitative determination by absorbance measurement at 238 nm. The hRF values for (1) and (2) were 51 and 79, respectively. Linearities were between 50 and 300 ng/zone for (1) and 200 and 1200 ng/zone for (2). The intermediate precisions were below 1.3 % (n=6). The LODs and LOQs were 2 and 5 ng/zone for (1) and 5 and 16 ng/zone for (2). Average recoveries were 99.7 % for (1) and 99.7 % for (2). The developed method successfully separated drug substances from degradation products formed under various stress conditions.
of three structurally related organophosphorus pesticides of forensic importance
J. Planar Chromatogr. 30, 154-163 (2017). HPTLC of chlorpyrifos (1), quinalphos_x000D_ (2), and triazophos (3) on silica gel with n-hexane ‒ acetone 9:1 and on RP-18 with acetonitrile ‒ water 4:1. The results indicated that the hRf values of all three pesticides increased with the polarity of the solvent.
Rev. Bras. Farmacogn. 27, 50-53 (2017). HPTLC of quercetin (1) and gallic acid (2) in Leea indica on silica gel with toluene – ethyl acetate – formic acid 5:4:1. Quantitative determination by absorbance measurement at 254 nm. The hRF values for (1) and (2) were 63 and 45, respectively. Linearity was between 200 and 1000 ng/zone for (1) and between 200 and 1200 ng/zone for (2), respectively. The intermediate precision was <2 % (n=3). The LOD and LOQ were 21 and 65 ng/zone for (1) and 15 and 55 ng/zone for (2). Recovery rate was in the range of 98.0-99.1 % for (1) and 99.3-100.2 % for (2).
coupled with bioactivity tests
J. Planar Chromatogr. 30, 121-125 (2017). Overpressured TLC of essential oil components of clove, rosemary, eucalyptus, tea tree, spearmint, thyme, and cinnamon on silica gel with toluene. The conditions in infusion mode were as follows: 50 bar, external pressure; 350 μL, rapid mobile phase flush; 500 μL/min, mobile phase flow rate; 3900 μL, mobile phase; 475 s, development time. The hRF values were 8 for α-terpineol, 12 for borneol, 17 for terpinen-4-ol, 20 for 1,8-cineole, 22 for R(–)-carvone, 31 for trans-cinnamaldehyde, 36 for eugenol and 43 for thymol. Antibacterial and antioxidant activities were also detected by infusion–transfusion OPLC hyphenated with Aliivibrio fischeri assay and 2,2-diphenyl-1-picrylhydrazyl (DPPH) radical assay, respectively.
