J. Liq. Chromatogr. Relat. Technol. 30, 2021-2036 (2007). TLC of carotenoid colorings of 95 commercial foods (33 for tomato color [lycopene], 38 for orange color [e.g. fatty acid ester of beta-cryptoxanthin], and 24 for marigold colorings [fatty acid ester of lutein]) on RP-18 with acetonitrile - acetone - n-hexane 11:7:2 and acetone - water 9:1. TLC of beta-carotene and paprika colorings of 77 commercial foods (e.g. capsanthin and its esters) on RP-18 with n-hexane - acetone - acetonitrile 2:7:1. TLC of quinone colorings (lac and cochineal colors) on RP-18 with methanol - 0.5 mol/L oxalic acid 11:9. TLC of anthocyanin colorings of 45 commercial foods (red cabbage color [derivatives of cyanidin acylglycoside]) on RP-18 with acetonitrile - 0.2 mol/L trifluoroacetic acid 1:2. Identification by recording of visible absorption spectra.
60th Indian Pharmaceutical Congress PA-202 (2008). HPTLC of 6-gingerol and 3-acetyl-11-keto-beta-boswellic acid on silica gel with n-hexane - ethyl actate 7:3 in a chamber saturated at ambient temperature. Quantitative determination by absorbance measurement at 254 nm. The hRf values were 48 and 58 for 3-acetyl-11-keto-beta-boswellic acid and 6-gingerol respectively. The recovery was 98.7-100.8 % for both compounds. The chromatographic conditions were suitable for routine analysis.
J. Liq. Chromatogr. Relat. Technol. 30, 2941-2951 (2007). TLC of 6-gingerol and 6-shogaol in commercial Ginger on silica gel with n-hexane - diethyl ether 2:3. Detection by spraying with anisaldehyde - sulfuric acid reagent. Evaluation under white light and quantitative determination by absorbance measurement at 577 nm.
Asian J. Chem. 19(6), 4286 - 4290 (2008). HPTLC of rofecoxib and tizanidine hydrochloride on silica gel with acetone - methanol 1:1. The method was linear in the range of 2200-3300 ng/spot and 180-260 ng/spot for rofecoxib and tizanidine respectively. The recovery was between 99.7 and 102.6 % for both compounds. The method was useful for the simultaneous estimation of the drug content in pure and tablet dosage form.
Asian J. Chem. 19(7), 5647-5651 (2007). HPTLC of levofloxacin hemihydrate and ornidazole on silica gel with n-butanol - water - acetic acid 3:1:1. Quantitative determination by absorbance measurement at 366 nm. The method was linear in the range of 1050-1400 µg/mL and 2600-2900 µg/mL for levofloxacin and ornidazole respectively. The recovery was between 97.3 and 98.0 % for both drugs. The method was suitable for simultaneous estimation of both drugs in combined tablet dosage form.
Acta Chromatographica 6, 7-14 (1996). HPTLC of fructose, glucose and sucrose on a channeled silica gel plate with concentration zone with acetonitrile - water 17:3 for three times (freshly prepared each time, taking 15 min per run) with chamber saturation for 10-15 min. Before, just the silica gel layer was impregnated by spraying with 0.10 M sodium bisulfate solution, and subsequently with citrate buffer (1:10 dilution of citrate buffer with water, pH 4.8), each followed by drying. Detection by spraying with 1-naphthol-sulfuric acid reagent, followed by heating at 100-110 °C for 5-10 min. Quantitative determination by absorbance measurement at 515 nm. The hRf values of fructose, glucose and sucrose were 47, 43, and 28, respectively, and selectivity regarding matrix was given. No zones other than the sugars were detected in sample chromatograms because of the selectivity of the detection reagent and the retention of the beverage components in the preadsorbent. Correlation coefficients (r) for linear regression of the calibration curves typically ranged from 0.90-0.99, with an average of 0.97. The precision in matrix was 2.5 % (n = 5). The mean reproducibility of the twofold sample analyses was 4 %, ranged between 0.45 % and 7.5 %. The accuracy of the method was 94.6 %, 97.0 % and 90.8 % for sucrose, glucose and fructose, respectively. Sugar concentrations in the samples ranged from 18.4-34.3 mg/mL.
Abstract No. 9147, IHCB (2009). HPTLC of quercetin in methanolic leaf extracts of Viola odorata on silica gel with ethyl acetate - formic acid - glacial acetic acid - water 100:11:11:26. Quantitative determination by absorbance measurement at 366/>400 nm for quantification. The extract contained 0.36 % quercetin.
J. Planar Chromatogr. 21, 263-265 (2008). HPTLC of nimbolide on silica gel in a twin trough chamber with ethyl acetate - hexane 1:1. Quantitative determination by absorbance measurement at 254 nm. The limits of detection and quantification were 3.3 and 1.0 µg/spot, respectively.
