LOD and LOQ were 119 and 362 ng/zone for (1), 33 and 100 ng/zone for (2), 248 and 750 ng/zone for (3) and 14 and 42 ng/zone for (4). Recovery was between 95 and 102 % for (1) to (4).
J. Planar Chromatogr. 36, 45-53 (2023). HPTLC of chlorogenic acid in the leaves of Gynura cusimbua on silica gel with ethyl acetate - formic acid - acetic acid - water 500:55:55:13. Quantitative determination by absorbance measurement at 366 nm. The hRF value for chlorogenic acid was 43. Linearity was in the range of 50-250 ngzone. Intermediate precisions were below 2 % (n=3).

J. Planar Chromatogr. 36, 3-8 (2023). HPTLC of Gentiana extract on silica gel with ethyl acetate - methanol - water 4:1:1. High Dynamic Range (HDR) photography was performed by combining nine Low Dynamic Range exposures (the whole camera range in 1-EV steps). Principal component analysis was applied on the classic exposures and HDR image, proving that HDR image contained the highest amount of extracted information from the TLC plate.
