and validation of a high-performance thin-layer chromatography method for the simultaneous estimation of berberine chloride and galangin in Tinospora cordifolia M
and their herbal formulations. J. Planar Chromatogr. 31, 451-459 (2018). HPTLC of berberine chloride (1) and galangin (2) in Tinospora cordifolia M._x000D_ and Alpinia galanga on silica gel with toluene ‒ ethyl acetate ‒ formic acid 3:6:1. Quantitative determination by absorbance measurement at 267 nm. The hRF values for (1) and (2) were 17 and 82. Linearity was between 200 and 1200 ng/zone. LOD and LOQ were 28 and 86 ng/zone for (1) and 2 and 5 ng/zone for (2), respectively. The intermediate precision was <2 % (n=3). Recovery was between 97.5 and 102.6 % for (1) and (2).
Biochemical Systematics and Ecology 13, 391-402 (1985). TLC on silica with ethyl acetate - pyridine - water - methanol 16:4:2:1.
Quantitative HPTLC of silybin - a comparison to quantitative HPLC. GIT Suppl. Chromatographie 3, 4-11 (1987). With the aid of an optimized HPTLC procedure silybin was quantitatively determined after extraction with methanol in the drug cardui mariae, besides Silydianin, Silydristin and Taxifolin. The extraction procedure was simplified and optimized with a view to systematic errors. The statistical comparison of the results with those established by HPLC, shows the equivalence of both analytical methods. Under the aspect of the expenditures (time, personnel, appliances) as well as total operating costs HPTLC turnes to be a most appropriate method for this routine analysis.
Yellow spots in the potato variety „Hertha“. J. Lebensm. Unters. Forsch. 186, 407-411 (1988). TLC of flavonols on silica with toluene - chloroform - acetone 40:25:35, on polyamide with chloroform - MEK - methanol 60:26:14; of flavonolglycosides on silica with ethyl acetate - MEK - formic acid - H2O 50:30:15:15; of sugars on cellulose with pyridine - n-butanol - H2O 24:12:6 and of p-hydroxycinnamic acids on polyamide with toluene - ethyl formate - formic acid 50:40:10. Detection of sugars with naphthoresorcinol or anisidine and under UV; of flavonols under UV.
Phytochemistry 28, 87-981 (1989). TLC of pisatin and maackiain on silica with chloroform - methanol 4:1. Detection with vanillin - HCl reagent. Determination of RM: TLC on RP-18 254 plates activated by heating at 120°C for 15 min. with acetonitrile - water 13:7. Visualization under UV and by exposing to iodine vapor.
Zuordnung und Zusammensetzung der Flavonoidglydoside-Banden in DC und HPLC sowie Vergleich mit den „Mexikanischen Arnikablüten“. (DAB 9 purity control. Assignment and composition of flavone glycoside fractions from TLC and HPLC; comparison with Mexican arnica blossoms.) Deutsche Apotheker Zeitung 130, 980-984 (1990). TLC of flavone glycosides on silica with formic acid – water – MEK – ethyl acetate 1:1:3:5. Detection by spraying with 1% diphenylboryloxyethylamine solvent (Naturstoff reagent after Neu) and 5% macrogol solvent and under UV 365 nm.
Acta Pharm. Sinica (Yaoxue Xuebao) 26, 471-474 (1991). Micellar TLC of quercetin, morin and rutin on polyamide with 4% tetradecylbenzyldimethylammonia (Zeph) chloride - acetylacetone - water 10:2:10:3. Investigation of the influence of micellar solutions, the type of the organic component in the solvent system, and the concentration of acetylacetone and Zeph on the chromatographic behaviors of the flavones.
J. Planar Chromatogr. 6, 129-137 (1993). HPTLC of vanilla extracts and reference substances on silica with chloroform - ethyl acetate - propan-1-ol 96:2:2 or 94:2:2; detection by postchromatographic derivatization with 2,4-DNPH in 25 mL 95% ethanol and 25 mL of 85% orthophosphoric acid for about 5 sec.
