JAOAC Int. 84, 1232-1241 (2001). HPTLC of ginkgolide A, ginkgolide B, ginkgolide C, and bilobalide on silica gel, modified by dipping into a 4% sodium acetate - 60% ethanol solution for 2 s and activated at 90°C for 10 min, with toluene - ethyl acetate - acetone - methanol 50:25:25:3 after equilibration of the plate for 30 min in a conditioning tray containing sulfuric acid aqueous solution (about 47% relative humidity). Detection after heating of the plate for 30 min at 160°C and observation of the fluorescent chromatogram under UV 366 nm. Quantification by densitometry at 366 nm.
Planta med. 68, 55-59 (2002). Analytical and preparative TLC of 3ß-angeloyloxy-8a-hydroxy-6ß-methoxyeremophil-7(11),9(10)-dien-8,12-olide, 2:3ß-angeloyloxy-6ß,8a-dihydroxyeremophil-7(11),9(10)dien-8,12-olide, 5:3,8-oxo-eremophila-6,9-dien-12-oic acid, 3:3ß-angeloyloxy-8a-hydroxy-6ß-ethoxyeremophil-7(11),9(10)-dien-8,12-olide, 4:3ß-angeloyloxy-8-oxo-eremophila-6,9-dien-12-oic acid on silica gel with chloroform - methanol 12:3:2 and dichloromethane - methanol 10:1.
J. AOAC Int. 89, 1-7 (2006). TLC of masticadienonic and 3-hydroxymasticadienonic acid on silica gel with hexane - acetone - formic acid - acetic acid 30:10:1:1. Quantitation by determination of the absorption at 200 nm. Detection by dipping into anisaldehyde - sulfuric acid reagent for 1 sec and heating at 100 °C for 5 min. Limit of detection was 0.1-0.2 µg/mL.
CBS 97, 6-7 (2006). HPTLC of absinthe (a beverage of the wormwood plant, Artemisia absinthium) on silica gel with acetone - acetic acid (98 %) - toluene - dichloromethane 1:1:3:5 over 70 mm. Detection by dipping in a solution of acetic anhydride - sulphuric acid - ethanol 1:1:10 followed by heating at 104 °C for 5 min. Quantitative determination by absorbance measurement at 554 nm. The hRf value of absinthin was 64 and selectivity regarding matrix was given. Linearity was between 0.1 and 10 g/L. The limit of detection and quantification for absinthin was 0.05 and 0.11 g/L, respectively. The precisions were better than 13.5 % (intraday) and 15.8 % (interday).
Analytical Chemistry - An Indian Journal 8(1), 77-81 (2009). An HPTLC method is reported for estimation of lupeol and beta-sitosterol in the whole plant powder of Asteracantha longifolia (Acanthaceae). The proposed method was also employed for estimation of beta-sitosterol in herbal formulation containing Asteracantha longifolia. Methanolic extracts of the sample were used for chromatography. HPTLC on silica gel with toluene - ethyl acetate - methanol 75:15:7. Derivatization with Liebermann-Burchard reagent. Densitometric quantification at 366 nm. The concentration of lupeol and beta-sitosterol was 0.162 mg/g and 0.045 mg/g, respectively in the whole plant, while the concentration of beta-sitosterol was 0.039-0.048 mg/g in the formulation. The method was suitable for the quality control of the herbal formulation.
Planta Med. 83(07), 661-671 (2017). Structural modifications of 9α- and 9β-hydroxyparthenolide (isolated from Anvillea radiata aerial parts) were performed either by Heck’s reaction (a palladium(II) acetate treatment in presence of triethylamine and iodoaryl in dimethylformamide), or by acylation (here, addition of aroyl chlorides and/or acetic anhydride in dichloromethane and pyridine). TLC for reaction monitoring of the 21 derivatives on silica gel with petroleum ether – ethyl acetate in various proportions (3:2; 1:4; 1:1). Detection under UV or under white light after spraying with 5 % phosphomolybdic acid in ethanol, followed by heating.
