- Browse and search by CBS classification: Select one of the 38 CBS classification categories where you want to search by a keyword
- Keyword register: select an initial character and browse associated keywords
- Search by CBS edition: Select a CBS edition and find all related publications
Registered users can create a tailor made PDF of selected articles throughout CCBS search – simply use the cart icon on the right hand of each abstract to create your individual selection of abstracts. You can export your saved items to PDF by clicking the download icon.
J. Chromatogr. 380, 386-392 (1986). TLC of humanmelanoma gangliosides on silica with chloroform - methanol - 0.2 % calcium chloride 60:35:8. Hydrolysis with 0.5 unit neuraminidase in 5 ml buffer maintained on plate for 18 h. Detection of the products specific to gangliosides GM2 and CD2 by an immunoperoxidase staining system after treatment with monoclonal antigangliotetraosylceramide.
J. Planar Chromatogr. 5, 35-40 (1992). HPTLC of lasalocid sodium, monensin sodium, narasin sodium, salinomycin sodium on silica and RP-18 with ethyl acetate – water 100:3 resp. with methanol – 5% aqueous acetic acid 9:1 (2 x). Lipids (i.a. L-a-phospatidylcholine-ß-linoleoyl-y-palmitoyl, dipalmitoyl L-a-phosphatidylethanolamine, triolein, oleic acid, L-a-dipalmitoyl phosphatidylcholine) were chromatographed with cyclohexane – ether – acetic acid 90:10:1 on silica, with chloroform on RP-18. VPF resposes on silica and RP-18 have been compared for both classes of compounds: the respose of the polycyclic ether antibiothics narasin and salinomycin on RP-18 plates was three times greater than on silica; lipids with the exception of cholesterol could be detected only on silica plates. Quantification by fluoro densitometry at 366/>400 nm.
Chromatogr. (Sepu) 14, 259-263 (1996). Two dimensional TLC of 30 amino acids, 40 organic acids and 20 nucleosides and related compounds on cellulose - silica with 1) isopropanol - ethyl acetate - acetone - methanol - para-amyl alcohol - NH3 - water 9:3:3:1:1:3:3, butanol - isopropanol - acetone - formic acid - water 18:8:8:3:6, 2) tert-butanol - ethanol - NH3 - water 5:6:1:3, isopentanol - petrol ether - ethanol - formic acid - propionic acid - water 45:100:25:20:1:1, 3) isopropanol - ethyl acetate - methanol - NH3 - water 5:3:1:3:1, isopropanol - saturated (NH4)2SO4 - water 4:77:19, for both direction, respectively. Detection under UV 254 nm, by spraying with 0.1 % acridine in ethanol, by spraying with ninhydrin-cadmium acetate reagent. Detection limit 10-10 - 10-11 mol, 2x10-8 - 5x10-8 mol, and 1x10-8 - 3x10-8 mol, respectively.
Chromatographia 52, (5/6), 363-366 (2000). Purification by liquid chromatography using the highly-substituted benzhydrylamine resin as stationary phase. Analysis of different fractions by TLC on silica gel with chloroform - methanol - aqueous CaCl2. Detection by spraying with ocinol - sulfuric acid reagent, and resorcinol - sulfuric acid reagent.
J. Liq. Chromatogr. Relat. Technol. 30, 2717-2727 (2007). Identification of lipid classes, e. g. fatty acid methyl esters, and polar lipids (presumably phospholipids), free fatty acids, sterols, triacylglycerols, fatty acid esters, by TLC on silica gel with n-hexane - acetone 25:4. Detection by spraying with 50 % ethanolic sulfuric acid and heating at 200 °C. The mushrooms contained a characteristic group of three isomeric hexadecenoic fatty acids (double bond in positions 6-, 9-, and 11-) which are resolved and determined separately for the first time.
J. Planar Chromatogr. 23, 198-200 (2010). Proposition of new methods for calculation of the partition coefficients of aliphatic compounds from experimental Rf values and the numerical values of selected topological indexes. The experimental partition coefficient (log Pexp) of cetyl alcohol was determined for the n-octanol-water system. Numerical values obtained were compared with theoretical values from a database (AlogPs, AC_logP, AB/LogP, ALOGP, milogP, and XLOGP2). HPTLC of cetyl alcohol, stearyl alcohol, palmitic acid, stearic acid, alpha-hydroxypalmitic acid, and 12-hydroxystearic acid on RP18 with methanol and with methanol - water 19:1 in a horizontal chamber at room temperature. Detection after visualization in iodine vapor.
International Journal of ChemTech Research 2(2), 851-855 (2010). Defatted powdered roots of Helicteres isora (Sterculiaceae) were extracted with ethyl acetate. TLC on silica gel with toluene - acetone - formic acid 25:5:2. The hRf value was 43. Densitometric evaluation at 540 nm. The method was linear in the range of 100-500 ng/band. Recovery was 98.4-99.9 %.
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 %.
