Part I. J. Planar Chromatogr. 12, 135-139 (1999). TLC of 21 coumarins and flavonoids on polyamide 11 and alumina with water - modifier 1:9; modifier: 1) methanol, 2) 2-propanol, 3) acetonitrile, 4) tetrahydrofuran, 5) dioxane in a horizontal sandwich chamber. Detection under UV 254 nm. Discussion of the selectivity of the systems, the adsorptive properties of the polyamide and the alumina, and the influence of different organic modifiers.
Chinese J. Pharm. Anal. (Yaowu Fenxi Zazhi) 20 (2), 121-124 (2000). TLC of 14 kinds of flavonoid drugs on polyamide film with 6 kinds of SDS / butanol - hexane - water micro-emulsions as the mobile phase. Detection by spraying with 1% AlCl3 in ethanol and under UV 365 nm. Identification of the flavonoid compositions in rutin, quercetin and scutellarin by fingerprint. Comparison of the results with those obtained with normal mobile phase, showing advantages of present method. Optimal mobile phase was a micro-emulsion containing 75% water - formic acid 19:1.
J. Planar Chromatogr. 15, 4-10, (2002). HPTLC of flavones and flavanones (myricetin, luteolin, apigenin, acacetin, hyperoside, quercetin, rutin, quercitrin, astragalin, kaempferol, isoquercitrin, naringenin, naringin, hesperitin, hesperidin) and phenolic acids (caffeic, ferulic, and chlorogenic acid) on CN-(cyanopropyl)-modified silica gel with e.g. 60% acetone in n-hexane for the development in the first direction and 50% methanol in water for the development in the second direction. Visualization with poly(ethylene glycol) 400 and 2-(diphenylboryoxo)ethylamine. Documentation at 366 nm.
J. Agric. Food Chem. 50, 1700-1705 (2002). TLC of (-)-epicatechin-(4b-8)-epicatechin and (-)-epicatechin-(4b-6)-epicatechin on cellulose with 6% aqueous acetic acid. Visualization by spraying with 5% vanillin solution in 10% hydrochloric acid in ethanol followed by heating.
J. Planar Chromatogr. 17, 459-463 (2004). TLC of standard solutions of nine flavonoids and six phenolic acids (cinnamic, o-coumaric, m-coumaric, p-coumaric, caffeic, ferulic acid, galangin, quercetin, pinocembrin, naringenin, apigenin, chrysin, kaempferol, morin, acacetin) on silica gel in pre-saturated developing chambers with 1) n-hexane - ethyl acetate - glacial acetic acid 31:14:5, or 2) chloroform - methanol - formic acid 88:7:5. After drying, bands were visualized under short- and long-wavelenghth UV light. Detection by spraying with 1 % aluminium trichloride solution and evaluation under long-wavelength UV light. Standards were chromatographed again with a propolis extract. First, plates were developed with mobile phase 1 (or 2), the eluent was evaporated, standard solutions were applied again, and the plate was rotated through 90 ° and chromatographed again with mobile phase 2 (or 1). The presence (or absence) of all standards was determined according to their Rf values and fluorescence colors. Quantitative determination by absorbance measurement at 254 and 366 nm.
J. Liq. Chromatogr. & Relat. Technol. 29, 2141-2151 (2006). HPTLC of flavonoids (with rutin, chlorogenic acid, hyperoside, and gallic acid as reference substances) on silica gel in a twin-trough chamber with ethyl formate - toluene - formic acid - water 60:3:8:6. Detection by dipping the hot plate (heated at 100°C for 2 min) into natural products reagent, followed by drying, dipping into polyethylene glycol 400 (10 g in 200 mL dichloromethane), and drying. Evaluation under UV 366 nm. With this method the geographical origin of the material can be determined. Toluene - acetone - formic acid 9:9:2 allows the discrimination of green from black and other speciality teas, based on the polyphenol pattern. Detection by dipping the hot plate (heated at 100°C for 2 min) into a solution of Fast Blue salt B, followed by detection under white light. For investigation of the alkaloid profil ethyl acetate - methanol - water 20:2.7:2, followed by detection under UV 254 nm is used. The amino acid profile is analyzed by using 1-butanol - acetone - acetic acid - water 7:7:2:4. Detection by dipping into ninhydrin reagent, followed by heating at 110°C for 3 min and evaluation under white light. The method for polyphenols was validated regarding specificity, stability, reproducibility, and robustness.
Chinese J. Food Sci. 29 (4), 291-295 (2008). HPTLC of celery extracts on silica gel with chloroform - methanol - water 360:46:7. Detection and identification of the flavonoids by the characteristic chemical reaction colors and the UV spectrum of the prepared samples. Quantitative determination of apigenin by absorbance measurement at 345 nm. The linearity was between 330 and 990 ng/zone. Precision ( % RSD) was 1.33 % (n = 5) and the recovery was 97.8 % (n = 5, RSD = 2.3 %).
Rev. Bras. Farma. 24, 330-340 (2014). TLC of hesperidin in the fresh fruits of Citrus sinensis on silica gel with n-butanol - acetic acid - water 4:1:5. Detection by spraying with methanol sulphuric acid (10 %), followed by heating at 110 ºC. Qualitative identification at UV 284 nm. The hRF of hesperidin was 61.
