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.
Chinese J. Trad. Pat. Med. (Zhongchengyao) 27 (2), 225-227 (2004). TLC on silica gel with 1) petroleum ether (30 - 60 ºC) - ethyl acetate 9:1; 2) benzene - glacial acetic acid 4:1. Detection 1) by spraying with 1 % vanillin solution and heating at 105 ºC for 10 min; 2) under UV 365 nm. Identification by fingerprint technique. Quantification of ferulic acid by densitometry at 325 nm. Validation of the method by investigation of linearity (0.16 µg - 1.6 µg, r = 0.9992); precision (RSD = 1.8 %, n= 5 within plate and RSD = 2.3 % plate to plate); reproducibility of five time assay towards the same sample (RSD = 0.5 %); and standard addition recovery (97.17 %, RSD = 0.9 %, n = 5). The results for three real life samples are given.

TLC of 14C-labeled pesticides (metribuzin, linuron, isopropylanilin, bentazon, metamitron, MCPA, mecoprop, isoproturon, MD-IPU, diuron, diazinon, simazine, 2,4-dichlorophenoxyacetic acid, chlorsulfuron, metsulfuron-methyl, thifensulfuron-methyl, tribenuron-methyl, triazinamine, methyl-triazinamin, terbutylazine) on silica gel and RP-18 in horizontal chamber with isopropanol - ethyl acetate - acetic acid 30:70:0.1, isopropanol - ethyl acetate - hexane - acetic acid 10:40:50:0.1 and 30:40:30:0.1, isopropanol - hexane - acetic acid 30:70:0.1, hexane - diethyl ether 1:1, methanol - water 3:2, methanol - water - acetic acid (pH 3) 3:2, methanol - water - ethyl acetate 13:5:2, acetonitrile - water 3:2, acetonitrile - water -phosphoric acid (pH <2) 1:9. After development the plates were exposed to a phosphor screen for 24 hours and analyzed by use of a Cyclone storage phosphor system.
J. Pharm. Biomed. Anal. 38, 180-185 (2005). A stability indicating HPTLC method is reported for estimation of cyclophosphamide in pharmaceutical preparations. HPTLC on silica gel with dichloromethane - methanol - acetic acid 97:3:2. Detection with alcoholic phosphomolybdic acid solution followed by heating at 190 °C for 10 min. Quantitative determination by absorbance measurement at 700 nm. Linearity was obtained between 0.40-1.20 mg/mL with recovery rates of 99.5 %. The method was validated for selectivity, specificity, accuracy, precision, and found to be stable for 28-70 days.
J. Planar Chromatogr. 18, 282-284 (2005). TLC and HPTLC of horseradish and mustard samples on silica gel with iso-propanol - 25 % ammonia 9:1 containing different volumes of water (1, 2, 3, or 5 parts). After development the compounds were visualized under UV light at 254 nm or by exposure to iodine vapor.
J. AOAC Int. 88, 1571-1577 (2005). TLC and HPTLC of narceine, morphine, codeine, thebaine, papaverine, and narcotine on silica gel with toluene - acetone - ethanol - 25% ammonia 20:20:3:1. Detection with Dragendorff’s reagent with sodium nitrite, densitometric evaluation at 520 nm. For UV-detection, Naturstoff reagent A (diphenylboric acid 2-amino ethyl ester) was used; quantitation by densitometry at 310 nm.
