The Cumulative CAMAG Bibliography Service CCBS contains all abstracts of CBS issues beginning with CBS 51. The database is updated after the publication of every other CBS edition. Currently the Cumulative CAMAG Bibliography Service includes more than 11'000 abstracts of publications between 1983 and today. With the online version you can perform your own detailed TLC/HPTLC literature search:
- Full text search: Enter a keyword, e.g. an author's name, a substance, a technique, a reagent or a term and see all related publications
- 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. Planar Chromatogr. 28, 316-322 (2015). HPTLC of pyridostigmine bromide in pharmaceutical formulations on silica gel with methanol - ethyl acetate - triethyl amine - glacial acetic acid 180:20:10:1. Quantitative determination by absorbance measurement at 270 nm. The hRF values for pyridostigmine bromide and its alkaline degradation product were 14 and 34, respectively. Linearity was in the range of 2-10 ng/zone. LOD and LOQ were 1.9 and 0.6 ng/zone, respectively. The intermediate precision was 0.8 % (n=9). Recoveries ranged between 98 and 100 %.
Rapid Commun. Mass Spectrom. 30, 321-332 (2016). The paper describes different technical and methodic improvements for interface configuration, source caps and transfer tube to enhance sensitivity and reliability in Direct Analysis in Real Time mass spectrometry (DART-MS) surface scanning. By doing so, the detectability of HPTLC-scanning DART-MS was increased by a factor of 34, which is crucial for analysis in the low-nanogram range on the plate and the hyphenation of HPTLC with DART-MS, but also for surface scanning in general. The modified device was shown to work highly quantitative.
Rapid Commun. Mass Spectrom. 29, 1288-1296 (2015). HPTLC of sphingomyelins (1), phosphatidylcholines (2) and phosphatidylethanolamines (3) on silica gel with chloroform - methanol - water - acetic acid 30:15:2:4 for the first step and acetone - acetonitrile - chloroform 5:4:2 for the second step. Detection by spraying with 0.5 % amido black 10B stain in 1 M NaCl. The method was coupled with matrix-assisted laser desorption/ionisation mass spectrometry for the analysis of (1) and (2) extracted from 5,6-dimethylxanthenone-4-acetic acid-treated xenograft tumours.

Acta Scientiarum 37, 367-374 (2015). HPTLC of ochratoxin A from Aspergillus carbonarius on silica gel with ethyl acetate - toluene - 90 % formic acid 5:4:1. Qualitative determination under UV light at 366 nm.
Food Control. 68, 310-329 (2016). Review of the methodologies to determine the occurrence of aflatoxin M1 (AFM1) and the fate of AFM1 during processing of milk and dairy products, such as yoghurt and cheeses, since 1996 until today. The review describes the application of TLC and HPTLC in raw and pasteurized milk, feta cheese, yoghurt, white cheese, ice cream and butter.
J. Planar Chromatogr. 29, 108-112 (2016). HPTLC of water-soluble vitamins (B1, B2, B6, C, and B12), amino acids and β-blocker enantiomers (carvedilol, (S)-(−)-propranolol hydrochloride, (±)-propranolol hydrochloride, and (±)-sotalol hydrochloride) on novel core–shell polymers consisting of hyperbranched (poly(ethyleneimine)) core surrounded by oligosaccharide shell (PEI-OS) as a component of the silica gel phase. The influence of the weight of the hyperbranched PEI core (5 and 25 kDa) was investigated. β-blocker enantiomers were separated using acetonitrile - methanol 7:3. PEI-maltose and PEI-lactose were the most effective polymers for the chiral separation of β-blockers.
Hawksw & P. James. Quim. Nova. 39, 456-461 (2016). HPTLC of chloratranorin (1), atranorin (2), ursolic acid (3), 2'-O-methylphysodone (4), physodic acid (5), physodalic acid (6) and physodic acid (7) in Hypogymnia tavaresii on silica gel with toluene – acetic acid 17:3. Detection by spraying with sulfuric acid – acetic acid – water 1:20:4, followed by heating at 120 °C for 20 min. The hRF values of compunds (1) to (7) were 76, 74, 49, 33, 20, 19 and 18, respectively.
Phytochemistry. 124, 68-78 (2016). HPTLC of polar lipids in ten species of microalgae included in two main linages (Plantae and Chromista) on silica gel with methyl acetate – isopropanol – chloroform – methanol – 0.25 % potassium chloride 25:25:25:10:4. Detection of phosphorous containing lipids by spraying with molybdenum reagent (molybdenum trioxide and metallic molybdenum in concentrated sulfuric acid followed by dilution with water). Those bands that gave negative response to the molybdenum reagent and migrate according to betaine lipid references from Chlamydomonas reinhardtii and Pavlova lutheri were subsequently visualized with iodine solution and scratched off. These isolated betaine lipids were eluted with 5 mL of chloroform – methanol 2:1.
