Journal of Natural Remedies 8(1), 61-67 (2008). During pharmacognostic studies on Sphaeranthus indicus (Asteraceae) the sesquiterpenoid 7-OH-eudesmanolide was isolated. HPTLC of the ethyl acetate soluble fraction of aqueous alcoholic Sphaeranthus indicus extracts, on silica gel with n-hexane - diethyl ether 3:7. The plant extract and the marker (7-OH-eudesmanolide) were chromatographed simultaneously. Quantitative determination by absorbance measurement at 213 nm.
J. AOAC Int. 91, 1149-1153 (2008). HPTLC of berberine on silica gel prewashed with methanol using n-butanol - acetic acid - water 8:1:1 in a twin-trough chamber with chamber saturation for 5 min at 33 °C at 57 % relative humidity. Quantitative determination by absorbance measurement at 350 nm.
Indian Drugs 45(12), 948-951 (2008). HPTLC of nebivolol hydrochloride and hydrochlorothiazide on silica gel with ethyl acetate - methanol - ammonia 17:2:1. Absorbance measurement at 280 nm. The method was linear in the range of 500-1500 µg/mL and 100-500 µg/mL for nebivolol hydrochloride and hydrochlorothiazide respectively. Recovery was 99.3-101.9 % for both compounds. The method is suitable for routine quality control.
J. AOAC Int. 91, 1174-1178 (2008). HPTLC of hederagenin on silica gel with toluene - ethyl acetate - formic acid 7:3:5 in a twin-trough chamber. Detection with anisaldehyde - sulfuric acid reagent by dipping for 1 s and heating for 7 min at 100 °C. Quantitative determination by absorbance measurement at 595 nm.
J. AOAC Int. 91, 1145-1148 (2008). TLC of alpha-mangostin on silica gel with dichloromethane - methanol 24:1 in a saturated twin-trough chamber. Quantitative determination by absorbance measurement at 320 nm.
60th Indian Pharmaceutical Congress PA-199, (2008). HPTLC of trifluoperazine and hydrochloride and chlordiazepoxide on silica gel with carbon tetrachloride - acetone - triethylamine 12:6:1. Quantitative determination by absorbance measurement at 262 nm. The method was linear in the range of 20-280 ng/spot and 50-700 ng/spot for trifluoperazine HCI and chlordiazepoxide. The method was suitable for routine quality control of combined dosage form.
J. Liq. Chromatogr. Relat. Technol. 30, 2193-2208 (2007). TLC of S,R-(+/-)-ketoprofen on silica gel (prewashed with methanol - water 9:1 and impregnated by dipping in a 0.03 mol/L solution of L-arginine in methanol for 2 s at 22 °C) with acetonitrile - water 5:1 containing several drops of acetic acid (to fix the pH < 4.8) in one-dimensional and two-dimensional development. Quantitative determination by absorbance measurement at 252 nm. The results of the investigations demonstrated the ability of S,R-(+/-)-ketoprofen to undergo oscillatory transenantiomerization.
J. Planar Chromatogr. 21, 361-366 (2008). OPLC of xanthine standards (caffeine, theophylline, theobromine) and green tea extract on silica gel (prewashed with 15 mL acetonitrile - water 17:3) with chloroform - trifluoroacetic acid - acetonitrile - methanol 760:40:67:133. Quantitative determination by absorbance measurement at 280 nm. Xanthine standards were used as model compounds to test the connected systems OPLC-UV and OPLC-DAD-ESI-MS. Sensitivity of OPLC-UV or OPLC-DAD was increased by hyphenation with ESI-MS coupled in series. After background subtraction the extracted ion chromatogram ( m / z = 181.1 Da) yielded well measurable peaks for theophylline and theobromine in tea leaf extract. Analysis time was 10 min only.
