Food Chem. 288, 1-7 (2019). HPTLC of sesamin (1) and sesamolin (2) in sesame seed extracts on silica gel with n-pentane - diethyl ether 3:2. Quantitative determination by absorbance measurement at 290 nm. Linearity was between 25 and 150 µg/mL for (1) and 12.5 and 75 µg/mL for (2). Intermediate precision was below 3 % (n=6). The LOD and LOQ were 1.3 and 4 µg/mL for (1) and 0.4 and 1 µg/mL for (2), respectively. Recovery rate was between 95 and 105 % for (1) and (2). Correlation of the HPTLC and a HPLC-PDA method was notably high.
J. Planar Chromatogr. 32, 411-420 (2019). HPTLC of oleuropein in olive leave samples belonging to 9 different Egyptian olive varieties on RP-18 with methanol - acetonitrile 7:3. Detection by dipping into a methanolic 2-aminoethyldiphenylborane reagent (0.5 %), followed by drying and dipping into methanolic PEG 400 solution (5 %). Qualitative determination under UV light at 366 nm. Captured images were processed using the ImageJ software in order to build 2 separate data matrices (before and after derivatization). Quantitative determination by absorbance measurement at 240 nm. The hRF value for oleuropein was 35. Linearity was between 0.1 and 0.6 µg/zone. Intermediate precision was below 1 % (n=6). The LOD and LOQ were 0.07 and 0.22 µg/zone. Recovery rate was 100.5 %.
J. Planar Chromatogr. 32, 365-370 (2019). TLC of gallic acid (1) and methyl gallate (2) in Guyinye residue extracts and Turkish gall (TG) cream on polyamide film with glacial acetic acid - methanol - ethyl acetate - formic acid 10:6:2:1. Quantitative determination by absorbance measurement at 280 nm. The hRF values for (1) and (2) were 57 and 72, respectively. Linearity was between 1 and 5 µg/zone for (1) and 250 and 1250 ng/zone for (2). Intermediate precisions were below 4 % (n=6). The LOD and LOQ were 3 and 10 ng for (1) and 75 and 250 ng for (2), respectively. Recovery rate was 98.6 % for (1) and 98.3 % for (2).
J. Ethnopharmacol. 229, 233-245 (2019). HPTLC of diarylheptanoid in the rhizomes of Alpinia officinarum on silica gel with chloroform - methanol - formic acid 85:20:2. Detection under UV light at 254 nm. The hRF value for diarylheptanoid was 90.
J. Planar Chromatogr. 32, 237-241 (2019). HPTLC of protocatechuic acid (1) and quercetin (2) in the fruits of Carissa carandas on silica gel with toluene - ethyl acetate - formic acid 6:3:1. Quantitative determination by absorbance measurement at 310 nm. The hRF values for (1) and (2) were 57 and 61, respectively. Linearity was between 100 and 600 ng/zone for (1) and (2). The intermediate precision was below 2 % (n=9). The LOD and LOQ were 33 and 100 ng/zone for (1) and 28 and 85 ng/zone for (2), respectivley. Recovery rate was between 96.9 and 99.8 % for (1) and 97.9 and 98.8 % for (2).
J. Planar Chromatogr. 32, 191-196 (2019). HPTLC of phenolic compounds in 11 dark beers, 25 light beers, 10 non-alcoholic beers and 4 malt beers on silica gel with ethyl acetate - formic acid - acetic acid - water 50:55:55:13. Detection by dipping into a (1) 0.5 % methanolic solution of 2-aminoethyl diphenylborinate (natural product reagent or Neu’s reagent), followed by dipping into a 5 % methanolic polyethylene glycol (PEG) 400 solution for enhancement and stabilization of the fluorescent zones, or (2) 0.2 % methanolic DPPH radical solution. Documentation under white light and UV 366 nm. Zones at hRF values of 8, 13, 36, 45, 52 and 85 had the most impact on the principal component (PC) analysis and were recognized as markers for discrimination between dark and non-alcoholic beers. HPTLC-ESI-HRMS/MS2 analysis allowed the identification of desdimethyl-octahydro-iso-cohumulone (hRF 85) and iso-n/ad-humulone (hRF 95) as the most active bands with radical scavenging property.
J. Planar Chromatogr. 32, 115-120 (2019). HPTLC of ellagic acid (1), gallic acid (2) and ferulic acid (3) in the leaves of Elaeagnus angustifolia on silica gel with toluene - ethyl formate - formic acid 5:6.6:1.5. Quantitative determination by absorbance measurement at 290 nm. The hRF values for (1) to (3) were 36, 47 and 69, respectively. Linearity was between 56-677 ng/zone for (1), 100-1207 ng/zone for (2) and 100-1205 ng/zone for (3). The intermediate precision was below 2 % (n=6). Recovery rate was 101.4 % for (1), 100.9 % for (2) and 100.2 % for (3).
