II. High-performance liquid chromatographic separation on silica by utilizing pre-investigation data from over-pressurized thin-layer chromatographic experiments. J. Chromatogr. 290, 135-141 (1984). Ion-pair formation and separation of fifteen organic acids by high-performance liquid chromatography, using the optimal conditions in prior thin-layer chromatographic experiments. OPTLC on silica with methanol - phosphate buffer pH 5.0 1:1, containing different amounts of cetrimide.
J. Liquid Chromatogr. 7, 1313-1320 (1984).TLC of eicosanoids (6-keto PGF1 alpha, 6-keto-PGE, TxB2, PGF2 alpha, PGE2, PGD2, 15-keto-PGE2, PGA2, PGB2, 5-HETE, 12-HETE, arachidonic acid, etc.) on RP-18 with 0.025 M phosphoric acid-acetonitrile 52:48. Detection by spraying with phosphomolybdic acid in methanol.
J. Planar Chromatogr. 7, 382-385 (1994). TLC of two groups of positional isomers of monoenoic fatty acids 6-18:1, 9-18:1, 11-18:1, 5-20:1, 8-20:1, 11-20:1, and 13-20:1, as their phenacyl esters on silica impregnated by immersion for ca. 20 s in either 0.5% or 1.0 % methanolic silver nitrate, with petrol ether - acetone 40:3. Quantification after treatment with sulfuryl chloride vapors for 30 min and, finally, heating at 180-200 °C for 30 min by densitometry at 450 nm.
J. Chromatogr. B 717, 93-118 (1999). A review with 207 references on the title topic, including comparison of the retention behavior of the aromatic acids on different adsorbents by TLC and HPLC, and the use of TLC for separation of phenolic acids demonstrated with application examples.
Abstract No. 9192, IHCB (2009). HPTLC of betulinic acid in hydro alcoholic extracts of Nelumbo nucifera rhizome and seed, on silica gel with chloroform - methanol - formic acid 49:1:1. Detection by spraying with anisaldehyde reagent. Quantitative determination by absorbance measurement at 420 nm. The method was linear in the range of 2-10 ng/spot, recovery was 98.1-98.4 %.
International Journal of ChemTech Research 1(4), 826-831 (2009). A herbal extract and herbal gel were extracted with 70 % ethanol, filtered and used for application. TLC on silica gel (plates pre-washed with methanol) with ethyl acetate - methanol - water - formic acid 15:2:1:1. The hRf value was 34. Densitometric evaluation at 252 nm. Glycyrrhizin monoammonium salt was used as standard. The method was linear in the range of 200-1000 ng/band, the recovery was 95.9-98.2 % . The glycyrrhizin contents in the extract and gel were in the range of 17.9-18.5 %.
