Proc. Intern. Symp. on Planar Separations Plan. Chrom. 305-307 (2003). TLC of flavonoids (7-O-glucoside luteolin, 7-O-glucoside apigenine, 5'-O-glucoside tricetin, 3-O-rhamnoside quercetin, 3-O-rhamnoside kaempferol, luteolin, quercetin, kaempferol, isoginkgetin, ginkgetin) on silica gel in a sandwich chamber, in a Personal OPLC chamber, and by planar electrochromatography method with 11 monocomponent, 8 binary phases in different concentration, and ternary and quaternary mobile phases. The best separation of flavonoids, biflavones, aglycones, glycosides was obtained with ethanol - ethyl acetate -dioxane - hexane (as solvent strength modifier).
leaves. J. Planar Chromatogr. 18, 244-248 (2005). Analytical and preparative TLC of coumarins from Peucedanum tauricum with bergapten, scopoletin, and coumarin A and B as standards on silica gel and on RP-2 with water - methanol 3:2 in horizontal chambers. Detection under UV light at 366 nm and densitometry at UV 366 and 320 nm. Re-chromatography with more selective mixtures of dichloromethane and acetonitrile 99:1 and 39:1. Identification by analytical co-chromatography with standards using mixtures of cyclohexane - ethyl acetate 3:1 and dichloromethane - acetonitrile 39:1.
J. Planar Chromatogr. 20, 53-56 (2007). HPTLC of flavonoids (quercetin glucuronide, hyperoside, isoquercitrin, quercetin galloyl galactoside, quercitrin) on silica gel with ethyl acetate - formic acid - water 136:5:6 in a horizontal chamber. Densitometric quantitfication of flavonoids at 350 nm.
International Journal of PharmTech Research 2(2), 1427-1430 (2010). Ashokarista formulations contain ashoka (Saraca indica) as the main ingredient. Its markers are catechin, (+)catechole, and (-)epicatechin. TLC of extracts and (+)catechin on silica gel with toluene - ethyl acetate - formic acid - methanol 15:15:4:0.1. Quantitative determination by densitometry in absorbance mode at 278 nm. For identification of the stem-bark of Saraca indica the fingerprint is evaluated after detection with anisaldehyde-sulphuric acid. The hRf value of (+)catechin was 54.
Plant Breeding 134, 129-134 (2015). HPTLC screening of flavonoids in more than 1800 taro hybrids (Colocasia esculenta (L.) Schott) on silica gel with ethyl acetate - methanol - acetic acid - formic acid - water 30:1:2:1:3. Detection by heating at 100 °C for 3 min, followed by dipping with natural product reagent. Qualitative determination by absorbance at 366 nm. Scoring of the absence and presence of a selection of 8 zones for each track followed by statistical retreatment permitted to sort samples per family. This method contributed to taro genetic improvement.
S. Afr. J. Bot. 100, 122-131 (2015). HPTLC fingerprint of Agathosma betulina and Agathosma crenulata on silica gel with toluene - ethyl acetate - methanol - acetonitrile - formic acid 10:3:3:2:2. Qualitative identification at UV 366 nm. The hRF values of rutin, chlorogenic acid and kaempferol were 15, 25 and 65.
J. Planar Chromatogr. 29, 423-428 (2016). HPTLC of lupeol (1) and ursolic acid (2) in the leaves of Bauhinia purpurea L., Bauhinia variegata L., Bauhinia acuminata L., and Bauhinia tomentosa L. on silica gel with toluene – ethyl acetate – formic acid 80:20:1. Detection by dipping into anisaldehyde – sulfuric acid reagent followed by heating at 40 °C for 3 min. Quantitative determination by absorbance measurement at 550 nm for (1) and 522 nm for (2). The hRF values for (1) and (2) were 46 and 68, respectively. Linearity was between 100 and 600 ng/zone for (1) and (2). The intermediate precisions were below 1.5 % (n=3). The LODs and LOQs were 40 and 100 ng/zone for (1) and 35 and 100 ng for (2). Recoveries were between 97.1 and 100.0 % for (1) and 98.0 and 99.2 % for (2).
Phytochem. Anal. 29, 5-15 (2018). TLC fingerprint of Ipomoea aquatica on silica gel with methanol – water from 1:1 to 9:1 (1) or methanol with 0.05 % trifluoroacetic acid – water with 0.05 % trifluoroacetic acid 1:1 (2). Detection by spraying with anisaldehyde sulfuric acid reagent. Detection under UV 254 nm, 366 nm, and for (2), white light (yellow bands at hRF 19 and 25). The post chromatographic visualization possibilities indicate the potential of TLC in qualitative fingerprint analysis.
