J. of Chromatogr. A 1568, 188-196 (2018). Mass spectra by DART-MS were recorded directly in situ the bioautogram, immediately after direct bioautography (DB). This allowed to detect bioactive analytes within the bioautogram and discriminate microorganism cells and polar bioassay medium ingredients which could otherwise stress the MS system. DB-DART-MS was used for bioactive compounds in cosmetics using the Bacillus subtilis and Aliivibrio fischeri bioassays for detection of Gram-positive and Gram-negative antimicrobials. Planar yeast estrogen screen was used for detection of estrogen-effective compounds. HPTLC-DART-MS of parabens in hand creams either on silica gel with petroleum ether - glacial acetic acid 20:3 or on RP-18W with methanol - water 1:1. Detection under UV 254 and 366 nm. Bioassay by immersing the neutralized chromatograms into the bacterial suspensions.
J. Planar Chromatogr. 32, 481-493 (2019). HPTLC of metformin hydrochloride (1) and ursodeoxycholic acid (2) on silica gel with toluene - ethanol - acetone - formic acid 90:40:50:17. Quantitative determination by absorbance measurement at 234 and 700 nm for (1) and (2), respectively. The hRF values for (1) and (2) were 19 and 80, respectively. Linearity was between 5000 and 40000 ng/zone for (1) and 1500 and 12000 ng/zone for (2). Intermediate precision was below 1 % (n=3). The LOD and LOQ were 195 and 592 ng/zone for (1) and 150 and 455 ng/zone for (2), respectively. Recovery rate was 100.5 % for (1) and 99.9 % for (2).

Bioautography by dipping into a 0.15 mg/mL solution of substrate Gly-Pro-p-nitroanilide hydrochloride in 50 % of ethanol, followed by ethanol removal in the hood and dipping into a 10 U/L DPP IV enzyme solution in TrisHCl buffer (pH 8.2, 70 mM), followed by incubation at 37°C for 40 min. Detection by dipping into a solution of 0.5 % sodium nitrite in 1.2 M hydrochloric acid, followed by drying slightly for 5 min and dipping into 0.05 % N-(1-naphthyl)ethylenediamine dihydrochloride solution. Further analysis by mass spectrometry using a TLC interface. The hRF value for the dipeptidyl peptidase IV inhibitor was 58.
