Detection under UV light at 254 and 366 nm and by spraying with 1 % vanillin in ethanol with several drops of concentrated sulfuric acid; or with 3 % iron chloride dissolved in 0.5 M hydrochloric acid solution for compounds with a phenolic hydroxyl group. The LOD for (1) to (14) under 254 nm ranged from 0.5 to 2.5 mM, while 0.1 to 2.5 mM under 366 nm. Quantitative determination by surface-enhanced raman spectroscopy (SERS).
Food Chem. 343, 128400 (2020). HPTLC fingerprint of Citrus bergamia fruits from the islands of Kefalonia, Corfu and R. Calabria on silica gel with chloroform - methanol - water 13:9:3. Qualitative identification under UV light at 280 nm.
J. Liq. Chromatogr. Relat. Technol. https://doi.org/10.1080/10826076.2021.1939046 (2021). HPTLC of picroside-I (1), andrographolide (2) and silybin (3) in Picrorhiza kurroa (roots), Andrographis paniculata (aerial parts) and Silybum marianum (seeds), respectively, on silica gel with n-butanol - glacial acetic acid - water 6:1:3. Quantitative determination by absorbance measurement at 254 nm. The hRF values for (1) to (3) were 49, 68 and 89, respectively. Linearity was between 60 and 600 ng/zone for (1) to (3). The intermediate precision was below 2 %. The LOD and LOQ were 15 and 45 ng/zone for (1), 22 and 67 ng/zone for (2) and 26 and 78 ng/zone for (3), respectively. Recovery was between 99.7 and 103.7 % for (1), 99.7 and 101.1 % for (2) and 99.0 and 101.7 % for (3).

DPPH bioautography assay by spraying with 0.04 % 2,2-diphenyl-1-picrylhydrazyl in methanol under dark conditions. Detection under UV light at 535 nm. The hRF values for the antioxidant compounds were 30 for flavanomarein, 37 for marein and chlorogenic acid, 45 for 5,7,3',5'-tetrahydroxyflavanone-7-O-glucoside, 62 for 3,5-dicaffeoylquinic acid and 76 for isookanin and okanin.
Anal. Bioanal. Chem. 412, 6789-3809 (2020). HPTLC of Ginkgo biloba extracts on silica gel with ethyl acetate - acetic acid - formic acid - water 100:11:11:26 (1) or toluene - ethyl acetate - formic acid 7:3:1 (2). Detection under UV light at 366 nm or by spraying with natural product reagent (NPR) and polyethylene glycol (PEG). The method allowed to distinguish between characteristic and uncharacteristic unfinished product samples based on the presence or absence of bands corresponding to caffeic acid, rutin, hyperoside, chlorogenic acid, and genistein standards.
