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.
J. Planar Chromatogr. 22, 109-113 (2009). HPTLC of purpurin on silica gel with toluene - ethyl acetate - formic acid 98:2:1 in a twin trough chamber saturated for 20 min at 25 +/- 2 °C. Quantitative determination by absorbance measurement at 255 nm. The limit of detection and quantification was 50 and 100 ng/band, respectively.
Abstract No. 9402, IHCB (2009). HPLC and HPTLC methods were developed for the simultaneous estimation of vasicine and vasicinone in Sida cordifolia and Sida acuta roots. HPTLC of vasicine and vasicinone on silica gel with ethyl acetate - methanol - ammonia 40:10:1. Quantitative determination by absorbance measurement at 300 nm. Linearity was 320-960 ng/spot (vasicine) and 80-400 ng/spot (vasicinone). Linearity by HPLC was 4-20 µg/mL. The HPTLC method was more suitable because of high throughput and low analysis time.
J. AOAC Int. 92, 410-418 (2009). HPTLC of agrimoniin, pedunculagin, ellagic acid, gallic acid and catechin and plant extracts on silica gel, RP-18 and amino phase in a horizontal chamber. The best resolution and selectivity were achieved with diisopropyl ether - acetone - formic acid - water 4:3:2:1, tetrahydrofuran - acetonitrile - water 3:1:6, and acetone - formic acid 3:2. Polyphenols were detected under UV light at 254 nm and in visible light after spraying with 1 % methanolic iron(III) chloride or bis-diazotized sulfanilamide and after treatment with a vanillin-hydrochloric acid reagent.
Chinese J. Pharm. Anal. 28 (5), 732-734 (2008). TLC of Alternanthera philoxeroides extracts on silica gel with chloroform – methanol 40:1. The method is suitable for the quality control of the TCM drug and its formulations.
J. Planar Chromatogr. 22, 283-286 (2009). HPTLC of withaferin and extracts of the powdered root on silica gel, prewashed with methanol, with toluene - ethyl acetate - acetone 2:3:3 in a twin trough chamber saturated with mobile phase for 30 min. Detection by spraying with anisaldehyde reagent followed by heating for 15 min at 105 °C; characteristic orange fluorescence was observed for whithaferin. Quantitative determination by absorbance measurement at 214 nm. The limit of detection and quantification for withaferin A was 258 and 782 ng/zone, respectively.
Abstract No. 9933, IHCB (2009). HPTLC of colchicines in Gloriosa superba (collected from different parts of India) on silica gel with ethyl acetate - methanol 200:27. The hRf value of colchicine was 29. Quantitative determination by absorbance measurement at 350 nm. The method was linear in the range of 50-1000 ng/spot. The sample collected from Kerala was found to contain highest level of colchicines (0.24 %).
International Seminar on Herbal Drug Research, PN-064 (2009). HPTLC of gallic acid as marker compound in triphala fast dispersable tablets on silica gel with ethyl acetate - toluene - methanol - glacial acetic acid 75:20:3:2. Results from HPLC analysis were comparable. The method was suitable for routine quality control of dispersable tablets formulation.
