J. Food Comp. Anal. 21, 577-581 (2008). HPTLC of a novel fluorescent compound of nutmeg (Myristica fragrance) on silica gel with hexane – diethyl eter – acetic acid 50:50:1. Detection under UV at 265 nm or by spraying with sulphuric acid 50% followed by heating at 180 °C. The major fluorescent band at hRf 63 was further purified on silica gel using dioxane – acetonitrile – acetic acid 70:30:1. The hRf value of the novel compound was 61. Quantitative determination by absorbance measurement at 376 nm. Linearity was between 1 to 50 µg/spot. The compound was identified as 2-methyl-1,4,4a,8a-tetrahydro-endo-1,4-methanonaphthalene-5,8-dione.
J. Planar Chromatogr. 22, 49-53 (2009). TLC of geranylgeraniol and plaunotol on silica gel with chloroform - n-propanol 24:1 or 48:1, or with ethyl acetate, in saturated chambers. Quantitative determination by absorbance measurement at 210 nm. Detection of plaunotol by exposure to iodine vapor for 10 min. The acyclic diterpenoid plaunotol present in Croton stellatopilosus leaves is a hydroxylation product, catalyzed by the enzyme geranylgeraniol-18-hydroxylase. The activity of the enzyme in cell-free extracts of C. stellatopilosus leaves was previously reported. In this study a new mobile phase (ethyl acetate) was used for determination of geranylgeraniol-18-hydroxylase in the 20,000 g and 100,000 g precipitates of the crude extracts. In addition ethyl acetate successfully separated plaunotol from various cytochrome P-450 inhibitors (ancymidol, metyrapone, and miconazole) frequently used for biochemical characterization of the hydroxylase enzymes.
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.
