J. Liq. Chromatogr. Relat. Technol. 43, 361-366 (2020). HPTLC of the dried root and rhizome of Rhodiola rosea on silica gel with ethyl acetate - methanol - water 77:13:10. Detection by spraying with 1) a solution of p-anisaldehyde (0.5 mL in 85 mL methanol, 10 mL acetic acid and 5 mL sulfuric acid), followed by heating at 105 ºC for 5-7 min, 2) a solution of 2-isopropyl-5-methylphenol (0.5 g in 95 mL ethanol and 5 mL sulfuric acid), followed by heating at 120 ºC and 3) NP solution (1 g diphenylboryloxyethylamine in 100 mL methanol) and PEG solution (5 g PEG-4000 in 100 mL ethanol). Detection under UV 254 and 366 nm. Effect directed detection was performed using 1) DPPH* radical reagent assay: spraying with 0.2 % 2,2-diphenyl-1-picrylhydrazyl solution in methanol, 2) AChE assay: spraying with the enzyme solution (20 units of AChE and 150 mg BSA in 150 mL 0.05 M TRIS buffer, pH 7.8), follwed by incubation at 37 ºC for 20 min and spraying with 50 mg Fast Blue B salt diluted in 100 mL of water and 3) Bacillus subtilis bioassay: dipping into bacterial suspension for 8 s, followed by incubation at 37 ºC for 17 h and spraying with 0.2 % MTT aqueous solution. The bioautographic tests showed presence of both antioxidants (DPPH assay) and antibacterials (Bacillus subtilis assay) in the methanolic plant extract, however no acetylcholinesterase inhibitors were found. As marker compound, rosavin was detected.
Ind. J. Pharm. Sci. 70 (3), 395 - 398 (2008). TLC of propranolol hydrochloride on silica gel with isopropanol - ethyl acetate - ammonia 2:17:1. Quantitative determination by absorbance measurement at 290 nm. The linearity of the method was between 200 and 2000 ng/spot. The method was successively applied for tablets, wherein, no interference from tablet excipients was observed.
Planta Medica 83(03/04), 239-244 (2017). HPTLC of flavokawin B (purity checked by TLC, followed by sulfuric acid detection) and a hexane maceration of Polygonum ferrugineum aerial parts on silica gel, twice in the same direction with n-hexane – ethyl acetate 4:1 (humidity 33 %). Detection of flavokawin B by densitometry at 366 nm (without derivatization). The hRf value was 53. The content of flavokawin B was 13.6 % in the hexane extract and 1.0 % in the dried plant.
Acta Chimica 127, 95-58 (1990). TLC of hydroxy-propylated dodecyl alcohol and dodecyl alcohol on silica with acetone - methanol - water 50:50:1.
J. Planar Chromatogr. 23, 198-200 (2010). Proposition of new methods for calculation of the partition coefficients of aliphatic compounds from experimental Rf values and the numerical values of selected topological indexes. The experimental partition coefficient (log Pexp) of cetyl alcohol was determined for the n-octanol-water system. Numerical values obtained were compared with theoretical values from a database (AlogPs, AC_logP, AB/LogP, ALOGP, milogP, and XLOGP2). HPTLC of cetyl alcohol, stearyl alcohol, palmitic acid, stearic acid, alpha-hydroxypalmitic acid, and 12-hydroxystearic acid on RP18 with methanol and with methanol - water 19:1 in a horizontal chamber at room temperature. Detection after visualization in iodine vapor.
J. Chromatogr. A 1560, 97-103 (2018). Proposal of a simple and convenient on-spot derivatization approach for the modification of hydroxyl-containing compounds for their analysis by TLC/MALDI. Post-chromatographic acylation of separated analytes with 3-bromopropionyl chloride with simultaneous quaternization of pyridine, resulted in derivatives with permanent positive charges, which, in contrast to the initial alcohols not ionizable under TLC/MALDI conditions, reveal intense peaks of their cationic moieties in MALDI mass spectra recorded directly from TLC plates. Demonstration of the method by applying to a series of mammalian and plant sterols, phenols and terpene alcohols.
J. Chromatogr. 538, 373-383 (1991). Preparative TLC of diacylglycerols (DAGS) on silica - boric acid 19:1 with chloroform - acetone 98:2. Detection under UV 254 nm. Elution of DAG isomers with chloroform - methanol - trimethyl borate 20:10:1. Analytical TLC of 11 DAGS on silver impregnated silica with silver nitrate - saturated mixture of chloroform - isopropanol 99:1. Identification of the correlation between mobility and polarity of DAG species.
Ind. J. Pharma. Sci. 72(1), 86-91 (2010). Three species of Plumbago (Plumbaginaceae), i.e. P. zeylanica, P. carpensis, and P. rosea were studied for different physico-chemical parameters in addition to the estimation of microbial contamination, aflatoxins and pesticide residues and heavy metal content. All three species are used as herbs. The fingerprint profile of each species was compared using plumbagin as marker. Chloroform extracts of each plant were subjected to chromatography on silica gel with toluene - ethyl acetate 4:1 in a saturated twin trough chamber. Detection under UV 254 nm and 366 nm. The hRf value of plumbagin was 70. The identity of plumbagin in the samples was shown by overlay of the UV spectra. Linearity was between 200 and 1000 ng/zone. The amount of plumbagin in the three species was between 0.01 and 0.17 %.
