Planta Medica 82(15), 1359-1367 (2016). The presence of hispidin (a styryl pyrone) and hispolon in a methanolic Soxhlet extract of powdered Inonotus hispidus was verified by TLC on silica gel with ethyl acetate – methanol - water 200:27:20. Detection under UV light before and after derivatization with Natural Product/PEG reagent, and with anisaldehyde sulfuric acid reagent (followed by heating for 5 min at 110 °C). The two phenolic compounds were confirmed and quantified by HPLC.

Planta Med. 83, 1035-1043 (2017). TLC on silica gel with detection with anisaldehyde or Kedde’s reagent, 1) with ethyl acetate to monitor the isolation of digitoxin, by flash chromatography, from a fraction of a methanolic extract of Digitalis lanata, 2) with ethyl acetate – dichloromethane 1:1 to monitor five different methods for the hemisynthesis (with silver oxyde and diphenylborinic acid) of glucoevatromonoside from evatromonoside, itself produced from digitoxin, 3) with ketone – methanol 19:1 to analyse the glucoevatromonoside produced by biotransformation of evatromonoside by the glycosyltransferase activity of suspension cell cultures of Digitalis lanata. Digitoxigenin was used as internal standard, using the methanol fraction of the cell lysates, either directly or after a purification by flash chromatography. Hemisynthesis was twice more efficient as biotransformation, but the yield did not reach 70%.

Biochemical Systematics and Ecology 14, 307-310 (1986). Isolation and purification of iridoid glucosides, cornoside acetate and glucose. TLC on silica with dichloromethane - methanol - water 70:30:3 for iridoid glycosides and toluene- acetone 7:3 for cornoside acetate. Detection with vanillin 3 % and sulfuric acid 1 % in ethanol as spray reagent, followed by heating at 110 °C for 5 min. Separation of glucose with acetonitrile - CS2 - water 85:5:10, spray reagent thymol 1 % and sulfuric acid 3 % in ethanol.

Helv. Chim. Acta 71, 1210-1219 (1988). TLC of highly oxygenated polyphenols on silica with the lower layer of chloroform - methanol - water 44:37:20 and HPTLC on RP-8 with methanol - water 7:3. Detection under UV. Determination of the antifungal activity by a TLC bioassay using spores of Cladosporium cucumerinum. Also droplet counter-current chromatography (DCCC).

Planta Med. 57, 172-175 (1991). Isolation of pure isoprenylated xanthones by preparative TLC on silica with hexane - acetone 3:1. Final purification of the isolated compounds by PTLC with chloroform - acetone 5:1. Detection with FeCl3.

J. of Natural Products 55, 1768-1771 (1992). TLC of podophyllotoxin-like lignans on silica with hexane - acetone 7:3 and with benzene - acetone - methanol 94:4:2. Detection with 4% phosphomolybdic acid containing a trace of ceric sulfate in 5% sulfuric acid. Also preparative TLC and flash chromatography using the same conditions. Excellent TLC conditions for the separation of closely related lignans.

Biochemical Systematics and Ecology 22, 813-818 (1994). TLC of cyanidin-3-glucoside, peonidin-3-glucoside, coumaroyl ester of cyanidin-3-glucoside on silica with chloroform -formic acid - acetic acid 9:1:1, benzene - ethyl acetate 17:1. Visualization by spraying with bromocresol green.

J. Planar Chromatogr. 12, 345-349 (1999). TLC of flavonoids and phenolic acids (i.a. ferulic acid, caffeic acid, chlorogenic acid, isoquercetrin, hyperoside, rutin) on silica gel with ethyl acetate - methanol - formic acid - water 200:27:5:20 and ethyl acetate - formic acid - water 8:1:1 as the most suitable mobile phase (out of 10 mixtures). Visualization by spraying with 1% methanolic diphenylboryloxyethylamine, then 5 % ethanolic polyethylene glycol 4000 and evaluation under UV 366 nm.
