J. Planar Chromatogr. 22, 363-366 (2009). HPTLC of 5-hydroxymethylfurfural in seven Turkish fruit wines and three Turkish vinegars on silca gel with toluene - ethyl acetate - 90 % formic acid 6:3:1 in a twin trough chamber saturated for 20 min. Quantitative determination by absorbance measurement at 286 nm. The limit of detection and quantification was 0.05 and 0.13 ng/mL, respectively.
J. Planar Chromatogr. 24, 482-486 (2011). HPTLC of (-)-epicatechin and procyanidin B2 in chocolates on cellulose with n-propanol - water - acetic acid 20:80:1. Detection by immersion for 1 s in 4-dimethylaminocinnamaldehyde. Quantitative determination by densitometry at 655 nm. The samples contained 13 mg/100 g each of (-)-epicatechin and procyanidin B2 with a relative standard deviation of 5.8 and 4.2 % (n = 6), respectively. The calibration curves were polynomial in the range of 2-30 ng/zone for (-)-epicatechin and 4-60 ng/zone for procyanidin B2. LOD was 0.2 ng/zone (0.7 pmol) and 2 ng/zone (3.5 pmol) as well as LOQ was 0.4 ng/zone (1.4 pmol) and 4 ng/zone (7 pmol) for (-)-epicatechin and procyanidin, respectively.
J. Ethnopharmacol. 175, 131-137 (2015). HPTLC of 11-hydroxymustakone (1), N-formylannonain (2) and yangambin (3) in Tinospora cordifolia on silica gel with chloroform - ethyl acetate - methanol 130:80:3. Detection by dipping into anisaldehyde sulfuric acid reagent, followed by heating at 100 °C for 5 min. Quantitative determination by absorbance measurement at 366 nm. LOD and LOQ were 75 and 225 ng/zone for (1), 150 and 450 ng/zone for (2) and 30 and 90 ng/zone for (3), respectively. The intermediate precision was below 3 % (n=3). Recovery for (1) to (3) was in the range of 99-108 %.
Planta Medica 83(01/02), 143-150 (2017). Preparative TLC on silica gel H to purify amide alkaloids from column chromatography apolar subfractions of aerial part methanolic extracts of: a) Piper flaviflorum: decenoylpiperidide (petroleum ether – acetone 10:1), N-methoxycinnamoyl-pyrrolidine, dihydropiperyline, stigmalactam, chingchengenamide A (petroleum ether – ethyl acetate 8:1); and b) P. sarmentosum: methylenedioxyphenyl-undecadienoyl/undecatrienoyl-pyrrolidine (petroleum ether – acetone 1:2), cinnamoyl-hydroxypyrrolidine and deacetylsarmentamide B (chloroform – methanol 9:1); detection with Dragendorffʼs reagent.
Part 2: Comparative study on centrifugal layer chromatography (CLC) and SCLC for the separation of furocoumarin isomers. J. High Resol. Chromatogr. 8, 132-134 (1985). Preparative separation of furocoumarin isomers (isobergapten, pimpinellin, bergapten, isopimpinellin, sphondin) on silica containing calcium sulphate hemihydrate with hexane - THF 7:3, hexane - chloroform - THF 63:16:1, dichloromethane. Detection by UV 254 and 366 nm.
Journal of Natural Products 50, 245-247 (1987). TLC on silica with benzene - methanol - 90:10. Visualization under UV.
Chromatographia 26, 145-148 (1988). Study of TLC retention and selectivity behavior of bufadienolides on phenyl-modified silica with various methyl cyanide - water or methanol - water mixtures. Discussion of the selectivity of the systems for the separation of cinobufagin, vesibufogenin and bufalin.
Planta Med. 58, 259-262 (1992). TLC of aloins and 10-hydroxyaloins on silica with the lower layer of chloroform – methanol – water 7:13:8. Detection by spraying with 5% KOH. This reagent allows to distinguish aloins (dark yellow fluorescence) from 10-hydroxyaloins (light yellow fluorescence). Excellent resolution of 10-hydroxyaloin A and 10-hydroxyaloin B. Also DCCC separations.
