International Journal of Pharmacy & Pharmaceutical Sciences 3(2), 227-230 (2011). TLC of beta-sitosterol-D-glucoside and withaferin-A in Withania somifera formulations on silica gel with chloroform - methanol 4:1. The hRf value of beta-sitosterol-D-glucoside was 21 and of withaferin-A 59. Quantitative absorbance measurement at 207 nm. The method was linear in the range of 50-500ng/band for beta-sitosterol-D-glucoside and in the range of 5-50 ng/band for withaferin-A.
simultaneous quantification of eight bioactive secondary metabolites from Cicer
microphyllum by high-performance thin-layer chromatography
J. Sep. Sci. 38, 4021-4028 (2015). HPTLC of eight natural products viz. stigmasterol (1), oleanolic acid-3-acetate (2), oleanolic acid (3), biochanin A (4), genistein (5), pratensein (6), chrysoeriol (7), and luteolin (8) in Cicer microphyllum on silica gel with n-hexane - ethyl acetate - formic acid 90:65:8. Detection by dipping into a solution of cerric ammonium sulfate reagent, followed by heating at 105 °C for 5 min. Quantitative determination by absorbance measurement at 366 nm. The hRF values for compounds (1) to (8) were 98, 89, 78, 70, 63, 42, 33 and 4, respectively. Linearity was in the range of 100-800 ng/zone for (1) to (8). LOD and LOQ were 60 and 90 ng/zone for (1), (5) and (8), 50 and 90 ng/zone for (2), 90 and 110 ng/zone for (3), 70 and 100 ng/zone for (4) and (6) and 80 and 110 ng/zone for (7). The intermediate precision was below 1.5 % (n=3). Recovery was in the range of 98-100 %.
J. Sep. Sci. 41, 398-415 (2018). Review of analytical methods for the analysis of cannabinoids and their metabolites in cannabis, including the application of TLC and HPTLC. The review highlighted the use of automated multiple development (AMD) and optimum performance (or over-pressure) layer chromatography (OPLC) as considerable improvements to the use of classic TLC for cannabis analysis.
Chem. Pharm. Bull. 32, 4942-4945 (1984). TLC of 7 mutagenic xanthones on silica. Quantification by densitometry. Investigation of the conditions of the analysis. The relationship between xanthone content and mutagenicity is discussed.
Biochemical Systematics and Ecology 15, 687-689 (1987). TLC of aristolochic acids on silica with chloroform - methanol 85:15 or 2:1. Quantification by spectrophotometry at 254 nm.
Phytochemistry 30, 337-342 (1991). TLC of various proanthocyanidins on silica with ethyl acetate – formic acid – acetic acid – water 140:2:1:59 or on cellulose with water. Detection under UV or by spraying with vanillin – sulfuric acid or anisaldehyde – sulfuric acid reagents. TLC of acetate derivatives on silica with toluene – acetone 2:1. Also column chromatography and droplet counter-current chromatography (DCCC).
I. Regular part of the model. J. Planar Chromatogr. 4, 460-466 (1991). Manual examination of the retardation behavior of 16 apolar, closely related coumarins in normal phase TLC using the regular part of the three-dimensional „PRISMA“ model. The results show a highly significant second order dependency between the retardation factor (Rt) and the solvent strength (vertical correlation), as well as between the retardation factor and the selectivity point (horizontal factor).
J. Planar Chromatogr. 8, 243-344 (1995). TLC of 15 oxygen-containing adamantanes on alumina with chloroform - acetone - methanol 36:12:1, chloroform - acetone 6:1, carbon tetrachloride - acetone 30:7 or chloroform - acetone 18:6 or on silica with chloroform - methanol 50:3 or 14:1. Detection by exposure to iodine vapor.
