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. 30, 264-270 (2017). HPTLC of quercetin (1), apigenin (2) and kaempferol (3) in the stem bark of C. macleodii, C. rothi and C. dichotoma on silica gel with toluene ‒ ethyl acetate ‒ glacial acetic acid ‒ formic acid 10:10:1:2. Quantitative determination at UV 254 nm. The hRF values for (1) to (3) were 64, 66 and 71. LOD and LOQ were 9 and 29 ng/zone for (1), 30 and 92 ng/zone for (2) and 57 and 173 ng/zone for (3), respectively. The intermediate precision (n=6) was below 2 % for (1) and (2).
Phytochem. Anal. 29, 452-462 (2018). HPTLC of apigenin(1), luteolin (2), kaempferol (3), quercetin (4), kaempferol‐3‐O‐glucoside (5), quercetin‐3‐O‐glucoside (6), isorhamnetin‐3‐O‐neohesperidoside (7) and rutin (8) in the fruits and aerial parts of Foeniculum vulgare (fennel), Pimpinella anisum (anise), Carum carvi (caraway), Cuminum cyminum (cumin), Coriandrum sativum (coriander), Apium graveolens (celery), Petroselinum crispum (parsley), and Anethum graveolens (dill) on silica gel with ethyl acetate – methanol – water – acetic acid 3:1:1:1. Quantitative determination by absorbance measurement at 254 nm. Heat maps and hierarchical clustering were performed for image processing. The hRF values for (1) to (8) were 97, 90, 83, 73, 30, 17, 7 and 2, respectively. LOD and LOQ were 54 and 166 ng/zone for (1), 52 and 157 ng/zone for (2), 58 and 177 ng/zone for (3), 37 and 112 ng/zone for (4), 57 and 172 ng/zone for (5), 54 and 164 ng/zone for (6), 55 and 169 ng/zone for (7) and 58 and 178 ng/zone for (8), respectively. The intermediate precision was <2 % (n=6). Average recovery was 98.4 % for (1), 92.3 % for (2), 95.3 % for (3), 96.8 % for (4), 94.5 % for (5), 95.6 % for (6), 95.1 % for (7) and 97.3 % for (8).
