Indian J. Pharma. Sci. 70(4), 529-531 (2008). HPTLC on silica gel with ethyl acetate - acetone - acetic acid 13:6:1 with chamber saturation for 15 min. Densitometric evaluation at 208 nm. The hRf value was 51 for quinapril hydrochloride and 76 for hydrochlorothiazide. The method was linear in the concentration range of 400-2800 ng/zone for quinapril and 500-3500 ng/zone for hydrochlorothiazide. The recovery was in the range of 98.3-100.8 %.
Indian Drugs 47(6), 59-61 (2010). HPTLC of gallic acid in bark powder of Terminalia crenulata (Combretaceae) on silica gel with toluene - ethyl acetate - formic acid - methanol 60:60:16:4 with chamber saturation for 30 min. Densitometric evaluation at 254 nm. The method was linear in the range of 200-1200 ng/band. Samples extracted with different solvents were compared. Both alcoholic and water extracts were found to contain gallic acid where as it was absent in the chloroform extract.
International Journal of PharmTech Research 1(4), 1644-1649 (2009). TLC of telmisartan and amlodipine besylate on silica gel with tetrahydrofuran - dichloromethane - methanol - 25 % ammonia 30:10:5:1. The hRf value for telmisartan was 22 and for amlodipine 45. Densitometric evaluation in absorbance mode at 326 nm. The method was linear in the range of 1200-7200 ng/band for telmisartan and 400-1400 ng/band for amlodipine. The average recovery was 100.7-101.5 %.
obtained by different techniques. J. Planar Chromatogr. 23, 320-322 (2010). HPTLC of thymol in Satureja hortensis L. extracts on silica gel with toluene - ethyl acetate 93:7. Detection by spraying with anisaldehyde reagent. Quantitative determination by absorbance measurement at 513 nm. The quantity of thymol extracted depends on the composition of the extraction solvent and the extraction technique. The best results were obtained by maceration with ethanol.
Asian Journal of Chemistry 23(1), 309-311 (2011). TLC on silica gel with toluene - isopropyl alcohol - acetic acid 12:12:1. The hRf values was 63 for etophylline and 75 for theophylline. Densitometric evaluation at 261 nm. The method was linear in the range of 200-400 ng/band for etophylline and 60-80 ng/band for theophylline.
J. Planar Chromatogr. 23, 411-414 (2010). OPLC of ascorbigen and 1’-methylascorbigen on silica gel with n-hexane for the first step and chloroform - methanol 9:1 for the second step; OPLC of trans-resveratrol on silica gel with chloroform - methanol 10:1. Detection by bioautography (immersion in E. amylovora cell suspension, incubation for 2 h at 26 °C and 100 % relative humidity, and staining with a solution of 80 mg MTT and 100 mg Triton X-100 in 100 mL water. Quantitative determination by densitometry.
J. Sep. Sci. 33, 2206-2210 (2010). HPTLC of fluoxetine on silica gel with toluene - glacial acetic acid 4:5. Derivatization of fluoxetine with 4-dimethylamino-azobenzene-4-sulfonyl chloride. Quantitative determination by absorbance measurement at 272 nm. The hRF of fluoxetine was 45. Linearity was between 0.05-0.35 ng/µL. Detection and quantification limits were 230 and 700 ng/µL, respectively. The intra-day and inter-day precisions showed a %RSD lower than 3.9 %. Recovery (by standard addition) was 94.7 %. The method was designed to cover the usual serum concentration level of patients taking the drug.
J. Planar Chromatogr. 23, 339-342 (2010). HPTLC of saccharin in foodstuffs (e. g. cola drinks, lemon juices, betel nut powder, mouth fresheners, ice candy, and tabletop sweeteners) on silica gel with chloroform - methanol - acetic acid 64:35:1 or acetone - isopropanol - acetic acid 60:39:1. Quantitative determination by absorbance measurement at 230 nm. Linearity was between 250 - 1250 ng/µL. The limit of detection and quantification for saccharin were 40 and 130 ng, respectively. Mean recovery from spiked samples was 102.3 % for cola drinks and 98.8 % for lemon juices. Relative standard deviation (% RSD) for cola drinks, lemon juices, ice candy, mouth freshener, betel nut powders, and tabletop sweeteners were 2.1, 4.2, 3.4, 3.0, 4.9, and 4.1 %, respectively.
