International Journal of ChemTech Research 2(2), 807-812 (2010). Chloroform and ethyl acetate extracts of leaves and bark of Ficus mollis (Moraceae) were subjected to TLC fingerprint profiling on silica gel with toluene - ethyl acetate - formic acid 16:2:1. Evaluation under UV 254 nm. Derivatization with vanillin-sulfuric acid reagent, followed by heating at 105 °C until colorization. In the bark 7 well-defined zones were observed, whereas in leaves 10 zones were observed. Heavy metal and mineral analysis was performed by atomic absorption spectroscopy.
62nd Indian Pharmaceutical Congress Abstract No. F-252 (2010). TLC of alizarin and betulinic acid on silica gel with toluene – ethyl acetate – formic acid 18:3:1. The hRf values were 53 and 58 for betulinic acid and alizarin, respectively. Quantitative determination by absorbance measurement at 287 nm. The method was linear in the range of 60-160 ng/band for alizarin and 300-800 ng/band for betulinic acid. The average recovery was in the range of 99.4-99.6 % for both compounds.
J. Chinese Modern Med. & Pharm. 17 (34), 52-53 (2010). TLC on silica gel with chloroform – ethyl acetate – methanol – formic acid 2000:25:50:1. Detection under UV 366 nm. Identification of rhaponitin in both medicines by comparison with the standard.
Phytochem. Anal. 22, 258-262 (2011). TLC of gomisin A (1), gomisin N (2) and schisandrin (3) in the fruits of Schisandrae chinensis on silica gel with toluene - ethyl acetate - formic acid 14:6:1. Quantitative determination by direct analysis in real time mass spectrometry (DART-MS). Linearity of (1) - (3) was between 0.5 and 5 nmole. The limits of detection and quantification were 60-200 pmole for (1), and 58-192 pmole for (2) and (3). Recovery (by standard addition) for (1) - (3) was between 104.0 and 120.2 %. TLC-DART-MS method provides faster and more specific quantification compared with the conventional densitometric and HPLC-UV methods.
Planta Med. 76, 133-136 (2010). TLC of mitraphylline on silica gel with (1) dichloromethane - acetone 5:4, (2) diethyl ether - ethyl acetate 1:1, and (3) dichloromethane - ethanol 19:1. The hRf value in system (1) was 83, in (2) 73, and in (3) 68. Detection by spraying with sulfuric acid - acetic acid - water 1:20:4 followed by heating at 120 °C and by Dragendorff’s reagent.
J. Planar Chromatogr. 24, 376-380 (2011). HPTLC of stem bark extracts from D. melanoxylon and lupeol and betulin on silica gel, prewashed with methanol, with ethyl acetate - hexane 9:41 with chamber saturation for 3 min at 29 +/- 4 °C and 65 +/- 5 % relative humidity. The hRf value was 46 and 25 for lupeol and betulin, respectively. Quantitative determination by densitometry in absorption mode at 560 nm for lupeol and 510 nm for betulin. Detection by derivatization with 5 % methanol-sulfuric acid reagent. The LOD and LOQ was 40 and 100 ng/zone for lupeol and 50 and 100 ng/zone for betulin, respectively. The instrument precision and repeatability (n = 6) were 0.8 and 1.3 % for lupeol and 1.1 and 1.2 % for betulin, respectively. The linearity range was 100-500 ng/zone for both lupeol and betulin. The intra-day and inter-day precision was 1.1-1.7 % and 1.3-2.0 % for lupeol and 0.8-1.9 % and 1.9-2.2 % for betulin.
Planta Med. 77, 271-276 (2011). Analytical and preparative TLC of limonoids and quinoline alkaloids (1’,2’-didehydro-7,8-dimethoxyplatydesmine, 3-chloro-8,9-dimethoxygeibalansine, dasylactone A, dasylactone B, dictamnine, 7,8-dimethoxymyrtopsine, isofraxinellone, fraxinellone, obacunone, limonoic acid, rutaevine, and rutaevine acetate) on silica gel with chloroform - methanol 30:1, 10:1 and 6:1. Detection under UV 254 nm and by spraying with 98 % sulfuric acid - ethanol 1:19 followed by heating.
Food Chemistry 132, 671-674 (2012). TLC of saponins on silica gel with n-butanol - water - acetic acid 12:2:1. Detection by dipping into a suspension of sheep erythrocytes for 20 s, then plates were taken out and held vertically for 30 s. White spots against a pink background appeared. The plate was immersed in phosphate-buffered saline for 30 s to remove excess blood on the plate surface and again held vertically for 30 min. The method is simple, specific, convenient and time saving for analysis of saponins by TLC for purification, chemoprofiling of plants, and nutraceutical applications.
