Linearity was between 90 and 426 ng/zone for (1), 64 and 304 ng/zone for (2) and 80 and 380 ng/zone for (3). Intermediate precision was below 2 % (n=6). Average recovery was 98.6 % for (1), 99.7 % for (2) and 100.0 % for (3).
J. Planar Chromatogr. 33, 617-630 (2020). HPTLC of aflatoxin B1 in marketed samples of corn, groundnut, rice, wheat and dried chillies on silica gel with chloroform - acetone 9:1. Quantitative determination by absorbance measurement at 366 nm. The hRF value for aflatoxin B1 was 36. Linearity was between 10 and 120 ng/zone. Intermediate precision was below 2 % (n=3). The LOD and LOQ were 1 and 3 ng/zone. Average recovery was 85.2 %.
J. of Chromatogr. Sci. 59 (6), 576-583 (2021). HPTLC of simeprevir (SMV) and sofosbuvir (SOF) on silica gel with ethyl acetate – hexane - methanol 5:4:1. The hRF of SMV was 67 and of SOF 43. Quantitative determination by densitometry at 273 nm. The linearity range was between 60-1000 ng/band for SMV and 70-1200 ng/band for SOF, with good correlation coefficients (0.9993-0.9997) for both. LOD was 15 and 22 ng/band and LOQ 44 and 66 ng/ band for SMV and SOF, respectively.
J. of Chromatogr. Sci. 59 (6), 536-547 (2021). HPTLC of pregabalin (PGB) and amitriptyline (AMT) as an active binary mixture in pure forms or in human biological fluids (plasma/urine) on silica gel with ethanol - ethyl acetate - acetone - ammonia solution 160:40:20:1. Detection by spraying with 3 % ethanolic ninhydrin solution. Quantitative determination by densitometry at 220 nm for AMT and 550 nm for PGB peaks after derivatization. The linearity range was 0.2 - 2.5 μg/band for PGB and 0.1-2.0 μg/band for AMT.
J. of Chromatogr. Sci. 59(5), 425–431 (2021). HPTLC of bromhexine hydrochloride (BHX), impurity B (IMB) and impurity C (IMC) on silica gel with hexane - acetone - ammonia solution 450:25:4. Quantitative determination by densitometry at 240 nm. The linearity was in the range of 0.40-10.00, 0.20-2.00 and 0.20-2.00 μg/band for BHX, IMB and IMC, respectively. Comparison with an HPLC method showed no significant differences regarding accuracy and precision.
J. of Chromatogr. Sci. 59 (2), 140-147 (2021). TLC of paracetamol (PC), propyphenazone (PZ) and caffeine (CF) in the presence of the two PC impurities 4-aminophenol and 4-nitrophenol, on silica gel with chloroform - toluene - ethyl acetate - methanol - acetic acid 60:60:10:20:1. Quantitative determination by densitometry at 220 nm.
J. of Chromatogr. Sci. 58 (8), 737-746 (2020). Presentation of a method for determination of the antimicrobial capability of the metabolite coriloxin, derived from mycoendophytic Xylaria sp. NBRTSB-20, and purified by column chromatography with its purity assessed by HPLC, UPLC-ESI-QTOF-MS, FT-IR and NMR. Determination of the antimicrobial capability by TLC–bioautography with the agar overlay technique. Evaluation under visible light. The LOD of coriloxin antimicrobial activity was 10 μg for Escherichia coli and 20 μg for Staphylococcus aureus and Fusarium oxysporum. Inter- and intra-day precision was below 6.6 %. The recovery was between 91.2 to 108.7 % with RSD values of 0.9-2.3 %.
J. of Chromatogr. Sci. 58 (6), 520 – 534 (2020). HPTLC of 10-hydroxy-2-decenoic acid (10-HDA) in royal jelly products marketed in Egypt, on silica gel with chloroform - acetic acid 10:1. Quantitative determination by densitometry at 210 nm. First and second derivative treatment of the data and comparison between three statistical regression methods: parametric, nonparametric and weighted regression (WR). Derivative treatment of the data improved the sensitivity of the chromatographic signals. The WR method was advantageous over the use of the other two models and resulted in an enhancement of the accuracy and precision of the 10-HDA analysis. Recovery was 99.9 % with WR and 99.6 and 98.6 % with the other statistical methods. Further, the royal jelly standard was subjected to forced degradation studies including the effect of hydrolysis, oxidation, photolysis and dry heat.
