- 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.
Chromatographia 61 (5-6), 307-309 (2005). Similarities and differences between the retention characteristics of octadecyl silica gel wettable with water used in TLC and RP-18 used in HPLC have been elucidated by use of the linear relationships between log k and RM. The stationary phases compared were investigated with the same mobile phases - binary mixtures of methanol and water, acetonitrile and water, and tetrahydrofuran and water. For these adsorbents of the same type but differing in specific surface area the correlation line was shifted by log (alpha system I / alpha system II). High values of the correlation coefficients obtained over the whole range of mobile phase organic modifier concentration examined indicated that the TLC systems could be used to predict HPLC conditions for flavonoid separation.
J Young Pharm 1(5), 82-85 (2010). HPTLC of ascorbic acid in different varieties of amla fruit (collected from different geographical regions) on silica gel with ethanol - acetic acid 19:1. The hRf value of ascorbic acid was 76. Densitometric evaluation at 254 nm. The method was linear in the range of 1-5 µg/band. Bigger fruits were found to contain higher concentrations of ascorbic acid. The reported method was applied for estimation of ascorbic acid in crude drug as well as in herbal and pharmaceutical dosage form with reproducible results.
International Journal of Pharmacy and Pharmaceutical Sciences 3(2), 42-44 (2011). TLC of andrographolide in Andrographis paniculata (Kalmegh), collected from different Indian geographical sources, on silica gel with chloroform - methanol 7:1. The hRf value of andrographolide was 41. Densitometric quantification at 231 nm. The method was linear in the range of 100-500 ng/band. The amount of andrographolide varied from 0.7-1.2 % in samples collected from different geographical regions.
J. Liq. Chromatogr. Relat. Technol. 38, 1767-1782 (2015). HPTLC of thiocolchicoside on silica gel with toluene - acetone - water 3:15:2. Quantitative determination by absorbance measurement at 277 nm. The hRf value of thiocolchicoside was 53. Linearity was in the range of 100-500 ng/zone. LOD and LOQ were 3 and 11 ng/zone, respectively. The intermediate/inter-day/intra-day precision (n=7) was below 1 %. Recovery (by standard addition) was in the range of 100-101 %.
J. Sep. Sci. 41, 398-415 (2018). Review of analytical methods for the analysis of cannabinoids and their metabolites in cannabis, including the application of TLC and HPTLC. The review highlighted the use of automated multiple development (AMD) and optimum performance (or over-pressure) layer chromatography (OPLC) as considerable improvements to the use of classic TLC for cannabis analysis.
Chem. Pharm. Bull. 32, 4942-4945 (1984). TLC of 7 mutagenic xanthones on silica. Quantification by densitometry. Investigation of the conditions of the analysis. The relationship between xanthone content and mutagenicity is discussed.
Biochemical Systematics and Ecology 15, 687-689 (1987). TLC of aristolochic acids on silica with chloroform - methanol 85:15 or 2:1. Quantification by spectrophotometry at 254 nm.
Phytochemistry 30, 337-342 (1991). TLC of various proanthocyanidins on silica with ethyl acetate – formic acid – acetic acid – water 140:2:1:59 or on cellulose with water. Detection under UV or by spraying with vanillin – sulfuric acid or anisaldehyde – sulfuric acid reagents. TLC of acetate derivatives on silica with toluene – acetone 2:1. Also column chromatography and droplet counter-current chromatography (DCCC).
