Planta Med. 83, 912-920 (2017). Two subfractions of the ethanol extract of Aristolochia cordigera roots were mixed and submitted to preparative TLC on silica gel with hexanes (mixture of hexane isomers) – ethyl acetate 3:2 to isolate hyrtiosulawesine, aristolochic acids I and IV, sodium aristolochates I and IVa. The same method applied to a subfraction of the acetone extract of the roots revealed hyrtiosulawesine and 3,4-dihydro-hyrtiosulawesine.

Chromatographia 20, 109-111 (1985). Study of TLC behaviour of 28 phenolic compounds on semicrystalline stannic tungstate layers with various solvent systems. Detection by spraying with suitable chromogenic reagents. Dimethyl sulfoxide was found to act as self detector for a number of phenols. A number of binary, ternary and quarternary separations of bioanalytical and immuno-physiological importance have been achieved

Phytochemistry 28, 67-69 (1989). TLC of oleuropein, dimethyloleuropein and elenolic acid glucoside on silica with ethyl acetate - methanol - water 200:33:27. Visualization by spraying with p-toluene sulfonic acid (1%) and vanillin (2%) in ethanol.

J. Planar Chromatogr. 3, 425-528 (1990). It is proposed the RM values of substances analyzed on silica with tertiary mobile phases may be predicted from one-parameter regression equations. Experimental RM values for a group of isomers investigated have been compared with theoretical values calculated both on the basis of the author’s own studies (RMy = f(RMx)), and from Oscik’s theory. Substances chromatographed: o-, m- and p-isomers of aminophenol, ethylphenol, cresol, nitroaniline, nitrophenol, toluidine, chloroaniline, chlorophenol, nitrotoluene, chlorotoluene.

J. Planar Chromatogr. 5, 286-289 (1992). TLC of phenols (e.g. phenol, nitrophenols, naphtols, resorcinol, pyrogallol, catechol, pyrocatechol, thymol, hydroquinone, orcinol, cresol, picric acid) on impregnated silica (20 g silica and 60 mL of a 1% aqueous sodium nitrite solution with chloramin-T (5% in 0.5% aqueous sodium hydroxide).

Part VIII. J. Planar Chromatogr. 8, 219-226 (1995). TLC of phenols and selected isomeric chlorophenols on silanized silica with 0.1 M potassium dihydrogen phosphate - methanol 7:3, pH 7, and 1 M NH3 - methanol 7:3, pH 11.3. Detection with solution of potassium dichromate (5 g) in 40% sulfuric acid (100 g), followed by heating at 110°C for 15 min. Values of RM, minimum lethal dose log MLD, and toxicity log LC50 were correlated with energy effect E, pKa values, and with numerical values of the topological indexes M.

J. of Natural Products 60, 533-535 (1997). TLC of alkenylphenols on silica with hexane - chloroform 1:1 or 1:4. Detection by spraying with vanillin-sulfuric acid reagent. Isolation of ardisenone by prep. TLC on silica with chloroform - methanol 19:1.

J. Agric. Food Chem. 46, 3406-3410 (1998). Analytical and preparative TLC of 4-O-acetylcoumaric acid, 7-O-acetylfujikinetin, 7-O-acetylformomonetin, 7-O-acetylfrormosin on silica gel with hexane - benzene - acetone - methanol 40:40:15:5 (two fold development) and chloroform - benzene - acetone 50:45:5 (two fold development). Visualization with sulfuric acid - formaldehyde 40:1.
