Indian J. Pharm. Sci. 72(2), 249-252 (2010). HPTLC of rosiglitazone on silica gel with methanol - toluene - chloroform - triethyl amine 2:161:1. Caffeine was used as internal standard. The hRf value of rosiglitazone was 31 and of caffeine 52. Densitometric evaluation at 264 nm. The method was linear in the range of 5-50 µg/band with average recovery of 99.8-100.2 %. The method was suitable for content uniformity testing according to USP and could be used for stability studies as well.
Ind. J. Pharma. Sci. 72(1), 39-45 (2010). The Ayurvedic Pharmacopoeia of India recognized roots of the three plants Cissampelos pareira, Cyclea peltata, and Stephania japonica (all Menispermaceae) as source for the marketed drug Patha. HPTLC fingerprint analysis of methanolic extracts of roots of all three plants on silica gel with n-butanol - ethyl acetate - formic acid - water 3:5:1:1. Detection under UV 365 nm (crude extract) and 295 nm (total alkaloids). Quantification of the marker berberine by HPLC. The three plants exhibit significantly different physico-chemical features and chromatographic fingerprints. Roots of C. pareira contained the highest concentration of berberine, S. Japonica contained very low amounts and C. peltata no berberine at all.
J. Chromatogr. Sci. 48, 68-75 (2010). TLC of cefaclor, cefadroxil, cefalexin and cefradine on silica gel with ethyl acetate - methanol - water in different ratios. The studied drugs had hRf values between 40 and 60. Detection of blue to violet colored zones after spraying with ninhydrin reagent. Quantification by densitometry. Linearity was in the range of 2-10 µg/zone with correlation coefficients ranging from 0.9990 to 0.9996 and determination coefficients from 0.9986 to 0.9992 for all studied drugs. The limits of detection and quantification for all studied drugs were between 90 to 230 ng/zone and 270 to 840 ng/zone, respectively.
J. of Chromatogr. A 1218 (19), 2676-2683 (2011). A review on bioautography on TLC plates as an important means of detecting the biological activity of a sample. The technique requires only small amounts of sample, is ideal for the investigation of plant constituents which often occur as complex mixtures, and can be used for the target-directed isolation of these constituents. In contrast to HPLC, many samples can be run at the same time on TLC, and organic solvents, which cause inactivation of enzymes or death of living organisms, can be completely removed before biological detection. Many bioassays are compatible with TLC and antimicrobial, radical scavenging, antioxidant activities and enzyme inhibition tests can be applied.
Acta Chromatographica 20(4), 685-695 (2008). Determination of p-coumaric and protocatechuic acids in an ether fraction from a methanolic extract of Aquilegia vulgaris L. by HPTLC on silica gel with mixtures of heptane, dichloromethane, diisopropyl ether, formic acid, and water in various ratios. Satisfactory separation of the phenolic acids was achieved by use of the multiple gradient development technique. HPTLC results of the quantities of p-coumaric and protocatechuic acids were somewhat higher (0.396 and 2.584 mg/g dry plant material, respectively), than those determined by HPLC (0.374 and 2.283 mg/g dry plant material, respectively). Both methods were satisfactory in the precision, expressed as relative standard deviation, and are useful for quality control of Aquilegia vulgaris extracts.
62nd Indian Pharmaceutical Congress Abstract No. F-273 (2010). TLC of camylofin dihydrochloride on silica gel with toluene – methanol – chloroform – 10 % ammonia 8:5:6:1. The hRf value was 35. The sample was subjected to different stress conditions (acid, base, oxidative, thermal, photolysis). The proposed method could effectively separate the drug from its degradation product.
62nd Indian Pharmaceutical Congress Abstract No. F-253 (2010). TLC of ambroxol hydrochloride and doxophylline on silica gel with n-butanol – toluene – ethyl acetate – 25 % ammonia 50:30:20:1. The hRf values were 36 and 45 for doxophylline and ambroxol, respectively. Quantitative determination by absorbance measurement at 258 nm. The method was linear in the range of 300-1100 ng/band for ambroxol and 100-1100 ng/band for doxophylline.
62nd Indian Pharmaceutical Congress Abstract No. F-262 (2010). TLC of carbamazepine on silica gel with ethyl acetate – toluene – methanol 5:4:1. Quantitative determination by absorbance measurement at 285 nm. The hRf value was 47. The linearity was in the range of 100-600 ng/zone with r2 = 0.9995. The limit of detection was found to be 17 ng/zone, whereas the limit of quantitation was found to be 50 ng/zone.
