Planta Medica 83(01/02), 104-110 (2017). TLC on silica gel 1) to monitor the column fractionation of the chloroform partition of a methanolic maceration of Caesalpinia pulcherrima roots (eluent not given); and for preparative isolation of 2) 8,9,11,14-didehydrovouacapen-5α-ol from a subfraction of the same (with n-hexane – dichloromethane – acetonitrile 50:50:1); 3) pulcherrimin E from another subfraction (with chloroform – methanol 49:1, followed by preparative HPLC); and 4) 6β-cinnamoyl-7β-acetoxyvouacapen-5α-ol and pulcherrimin D, obtained by acetylation (in pyridine and acetic anhydride) from cinnamoyl-7β-hydroxyvouacapen-5α-ol and pulcherrimin A, respectively (eluent not given).

J. Planar Chromatogr. 30, 392-400 (2017). HPTLC of 13 Achillea species on silica gel with toluene – ethyl acetate – formic acid 50:49:1. Detection by spraying with anisaldehyde reagent, followed by heating at 126 °C for 10 min. TLC chromatograms were photographed and processed with ImageJ program. Also TLC on cyano phase with 2-propanol – n-heptane 1:1 and ethanol – water 3:2 for dichloromethane extracts and methanol – water 2:3 for methanolic extracts. Detection by spraying with 1 % solution of diphenylborinic acid 2-aminoethylester in methanol, followed by drying and spraying with 5 % solution of polyethylene glycol in methanol. Detection under UV 366 nm. Principal component analysis, similarity and distance measures were used to confirm the similarity between the studied samples.

Planta Medica 83(14/15), 1200-1206 (2017). The fractionation on cyclodextrane with methanol of the butanol-soluble parts of a methanolic macerate of Gymnocarpos decander aerial parts was monitored by TLC on silica gel with n-butanol – acetic acid – water 12:3:5. Detection by derivatization with cerium sulfate–sulfuric acid reagent. Through further analysis of the 5 resulting fractions, roseoside and heterosides of quercetin, of isorhamnetin and of tetrahydroxyoleanene were detected._x000D_
