J Young Pharm 1(4), 359-363 (2010). TLC of efavirenz on silica gel with acetonitrile - water - glacial acetic acid 12:8:1 in a twin-trough chamber saturated for 10 min. Densitometric evaluation at 247 nm. The method was linear in the range of 10-400 ng/band. The average recovery was 99.7 %.
A chromatographic study. J. Planar Chromatogr. 23, 277-281 (2010). TLC of cardiolipin, monolysocardiolipin, and phosphatidylethanolamin plasmalogen on silica gel and alumina pre-washed sequentially with chloroform - methanol 2:1 and acetone. For one-dimensional chromatography the mobile phase was 1-propanol - chloroform - ethyl acetate - methanol - water 50:50:50:21:18. Detection of phospholipids with thionine reagent. Two-dimensional chromatography in the first direction with the mobile phase mentioned before and in the second dimension with hexane - diethyl ether 4:1 after hydrolysis with 1 % hydrochloric acid to reveal alkenyl phospholipids. Detection by spraying with leucofuchsin reagent. TLC of choline lipids, phosphatidylcholine, and sphingomyelin on alumina with chloroform - methanol - water 65:30:4. Detection by treatment with Biebrich scarlet. Densitometric evaluation at 600 nm for thionine reagent and at 560 nm for leucofuchsin reagent.
Rasayan J. Chem. 2(3), 720-723 (2009). HPTLC of cefetamet on silica gel with toluene - chloroform - methanol 3:6:1. The hRf value of cefetamet was 35. Densitometric evaluation at 236 nm. The method was linear in the range of 1-5 µg/band. The recovery was 99.3-101.5 %. The method was found suitable for routine quality control.
J. Planar Chromatogr. 23, 406-410 (2010). TLC and OPLC of essential oil of thyme (thymol, carvacrol, and linalool as standards) on silica gel with chloroform (previously extracted with a 0.1 % aqueous solution of sodium hydrogen carbonate and dried on sodium sulfate to eliminate the stabilizer amylene, free hydrochloric acid, and chlorine) in an unsaturated chamber. Detection at 254 nm, by spraying with vanillin - sulfuric acid reagent (50 mg vanillin with 12 mL ethanol and 200 mL 98 % sulfuric acid) and heating to 70 °C for 10 min, and by use of the BioArena system. Quantitative determination by densitometry at 275 and 600 nm (dual-wavelength measurement).
Analytical Science 25(1), 57-62 (2009). HPTLC of minocycline on silica gel plates previously treated with 10 % EDTA solution of pH 9.0 with methanol - acetonitrile - isopropyl alcohol - water 10:8:1:1. The hRf value was 32. Densitometric evaluation at 345 nm. The method was linear in the range of 100-1200 ng/band for all biological samples. The average recovery was 95.1 %. The method was found suitable for estimation of the drug in different biological fluids (human plasma, saliva, gingival fluid) and can be used for pharmacokinetic studies.
Eurasian J. Anal.Chem. 5(1), 21-24 (2010). A stability-indicating HPTLC method has been developed for simultaneous estimation of amlodipine besylate and nebivolol hydrochloride. HPTLC on silica gel with ethyl acetate - methanol - 25% ammonia 17:2:2. The hRf value of amlodipine besylate was 40 and of nebivolol hydrochloride 60. Densitometric quantification at 240 nm for amlodipine and 260 nm for nebivolol. The method was linear in the range of 500-2000 ng/band for both compounds. Degradation products formed under stress conditions (acid, alkali, oxidative, dry heat, photo degradation) were well separated from the main compound. The method was suitable for quality control and stability studies.
International Journal of ChemTech Research 2(2), 1042-1046 (2010) HPTLC on silica gel with dichloromethane - methanol 9:1 in a twin-trough chamber saturated for 30 min. The hRf value was 70. Densitometric evaluation in absorbance mode at 254 nm. The method was linear in the range of 400-2000 ng/band. The average recovery was 101.2 %.
Phytochem. Anal. 21, 556-560 (2010). HPTLC of betulinic acid in the rhizomes of Nelumbo nucifera on silica gel with chloroform - methanol - formic acid 49:1:1. Detection by spraying with anisaldehyde - acetic acid - methanol - sulfuric acid 5:100:850:50 and drying at 50 °C for 10 min. Quantitative determination by absorbance measurement at 420 nm. The hRf of betulinic acid was 30. Linearity was between 2 and 10 µg/zone. Detection and quantification limits were 0.4 and 2.30 µg, respectively. The intra-day and inter-day precisions were 0.4 % and 0.3 % (n=3) respectively. Recovery (by standard addition) was 98.4 %.
