Cumulative CAMAG Bibliography Service CCBS
Our CCBS database includes more than 11,000 abstracts of publications. Perform your own detailed search of TLC/HPTLC literature and find relevant information.
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. 17, 229-232 (2004). HPTLC of progesterone on silica gel in an automatic multiple development chamber (AMD) with toluene - 2-propanol 9:1 without chamber saturation and with 10 min drying time. Visual inspection under UV light at 254 nm. Quantitative determination in reflectance mode at 252 nm. Limits of quantitation and detection were 25 and 5 ng/zone.
56th IPC 2004, Abstract No. GP-36. HPTLC for the standardization of gallic acid in alcoholic extracts of Aphanamixis polystachya (Meliceae) on silica gel with toluene - ethyl acetate - formic acid - methanol 15:15:4:1. Rf value of gallic acid was 0.45, linearity was 15 - 75 mg/mL. Formulations were found to contain 9.56 % of gallic acid. Gallic acid is the main phenolic compound and can be used for standardization of the crude drug.
J. AOAC Int. 88, 1537-1543 (2005). HPTLC of caffeine, acetaminophen and acetylsalicylic acid on silica gel with concentration zones using methanol - ethyl acetate 3:17. UV absorption densitometry is used for the quantitative determination of caffeine. Precision, accuracy, linearity, limits of detection and quantitation, and selectivity were validated. - A comparative study using a caffeine standard solution and a multicomponent analgesic tablet solution containing caffeine, acetaminophen, and acetylsalicylic acid showed that manual application on the concentration zone, and instrumental application on the silica gel gave quite similar results in terms of number of theoretical plates, resolution, limit of detection, and linearity.
J. Planar Chromatogr. 18, 164-166 (2005). TLC of non-steroidal anti-inflammatory drugs (NSAID), i.e. mefenamic acid, naproxen, ibuprofen, flurbiprofen, ketoprofen, paracetamol, and diclofenac, on silica gel with chloroform - methanol , chloroform - ethyl acetate, acetonitrile - methanol - water, acetonitril - methanol in different proportions. Detection with iodine vapor.
J. Planar Chromatogr. 18, 326-329 (2005). HPTLC of levonorgestrel on silica gel (prewashed with chloroform - methanol 1:1 and once with the mobile phase, dried and activated at 100 °C for 15 min) with toluene - 2-propanol 9:1 in an automatic multiple development chamber without chamber saturation. Visual examination under UV light at 254 nm; quantitation by densitometry at 250 nm.
J. Planar Chromatogr. 18, 380-383 (2005). HPTLC of ethamsylate in tablets on silica gel (pre-washed with methanol) at 25 +/-2 °C with chloroform - methanol -acetic acid 10:5:1 in a pre-saturated twin-trough chamber. Quantitative determination by absorbance measurement at 300 nm. The validated calibration range was 500-2500 ng per spot (r = 0.997).
J. Planar Chromatogr. 18, 294-299 (2005). TLC of (+/-)-metoprolol tartrate and (-)-alprenolol tartrate on silica gel, with concentrating zone, on RP-18, on LiChrospher silica gel and on alumina, previously impregnated with the mobile phase (ethanol - water 7:3, containing D-(-)-tartaric acid as chiral selector). Detection under UV light at 254 nm and densitometric scanning at 230 nm. Direct separation of the enantiomers of (+/-)-metoprolol tartrate was achieved.
J. Pharmaceutical Research 4 (3), 55-57 (2005). HPTLC of indapamide on silica gel with toluene - methanol 7:3. Quantitative determination by absorbance measurement at 246 nm. The method was linear within the range of 1.4-3.7 µg/mL. Mean recovery values were 99.46-100.29 %. The method was validated for accuracy, precision, and specificity.
