J. Planar Chromatogr. 21, 233-236 (2008). Connection of two-dimensional chromatography with multiple gradient development. 2D HPTLC of anthraquinone derivatives (1,8-dihydroxyanthraquinone, franguloemodin A, aloeemodin, rhein, frangulin A, aloin, sennoside B) on silica gel. Bandwise application at the right and left corner of the plate, then development by use of multiple gradient development [G. Matysik, Chromatographia 43, 39-41 (2004)], e.g. for step 1 hexane - dichloromethane 1:1, for step 2 (hexane - dichloromethane - ethyl acetate - 80 % formic acid 50:40:10:1) and for step 3 hexane - dichloromethane - ethyl acetate - methanol - formic acid 40:40:20:5:1. After drying the plate was developed from the left and right edge with hexane - dichloromethane - formic acid 60:40:1 for step 1 and with hexane - dichloromethane - ethyl acetate - formic acid 60:35:5:1 for step 2. Quantitative determination by absorbance measurement at 440 nm. Deteciton of anthranoids in daylight and after derivatization with 10 % potassium hydroxide in methanol.
CBS 102, 10-12 (2009). HPTLC of diterpene lactones (ginkgolides A, B, C, and bilobalide) in aqueous Ginkgo biloba leaf extracts on silica gel (impregnated by dipping into a 4 % solution of sodium acetate in methanol - water 3:2 for 5 s followed by drying at room temperature for 1 h) with toluene - acetone 7:3 with chamber saturation for 20 min. After twofold development over 60 mm the plate is heated at 150 °C for 1 h for detection of active compounds. Quantitative determination by absorbance measurement at 254 and 400 nm. The correlation coefficients of the calibration curves were = 0.9971 and relative standard deviations were = 2.0 %. Intraday precision was 1.1-1.2 %, interday precision 1.1-1.3 % and recovery 98.5-104.6 %. The average content in leaves was 0.078 (in % of dry weight) for ginkgolide A , 0.072 for ginkgolide B, 0.076 for ginkgolide C, 0.062 for bilobalide and 0.29 % for total diterpene lactones.
60th Indian Pharmaceutical Congress PG-251 (2008). HPTLC of glycyrrhetinic acid and piperine in haematinic herbomineral capsule formulation on silica gel with toluene - ethyl acetate - glacial acetic acid 25:15:1. Quantitative determination by absorbance measurement at UV 254 nm. The method was linear in the range of 0.8-2.4 ng/spot (glycyrrhetinic acid) and 10-50 ng/spot (piperine). Recovery was 96.3-98.6 %.
60th Indian Pharmaceutical Congress PA-224 (2008). HPTLC of aloe-emodin in extract of Rheum Emodi (prepared by supercritical fluid extraction) on silica gel with toluene - acetone - formic acid 80:20:1. Quantitative determination by absorbance measurement at 254 nm. Linearity was in the range of 100-400 ng/spot. Compared with other extraction techniques supercritical fluid extraction was more effcient and less time consuming.
60th Indian Pharmaceutical Congress PG-258 (2008). HPTLC of isovitexin in Passiflora incarnata raw material and extract on silica gel with ethyl acetate - formic acid - glacial acetic acid - water 100:11:11:26. The plant was found to contain 0.087 % w/w of isovitexin.
Abstract No. 9712, IHCB (2009). HPTLC of extracts from leaves of Dendrophthoe falcata on silica gel with methanol - formic acid - water 40:3:57. Quantitative determination by absorbance measurement at 280 nm using quercetin as marker.
J. Planar Chromatogr. 22, 367-369 (2009). HPTLC of triterpenoids (alpha- and beta-amyrin, oleanolic acid) on silica gel prewashed with methanol and dichloromethane, with dichloromethane - ethyl acetate 37:3. in a horizontal chamber saturated for 15 min. Detection by spraying with 8 % sulfuric acid in ethanol and heating at 105 °C for 3 min. Evaluation in daylight and under UV 366 nm. Quantitative determination by absorbance measurement at 520 nm.
J. AOAC Int. 93, 1617-1621 (2010). HPTLC of aconitine on silica gel with ethyl acetate - ethanol 3:1 at 22 °C in a saturated twin-trough chamber. The hRf value of aconitine was 33. Quantitative determination by absorption measurement at 238 nm. LOD and LOQ was 20 and 70 ng/band, respectively. The linearity with respect to peak area was in the range of 300 to 1800 ng/band with an r of 0.9991. The repeatability (RSD) was 0.85 %; and the inter-day and intra-day precision (RSD) was 1.01-1.38 and 1.04-1.34 %, respectively.
