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. Ethnopharmacol. 235, 361-374 (2019). HPTLC of colchicine (1) and withaferin A (2) in the polyherbal ayurvedic formulation Peedantak Vati (PV) on silica gel with chloroform -
methanol - water - formic acid 140:13:2:4. Quantitative determination by absorbance measurement at 218 nm. The hRF values for (1) and (2) were 22 and 28, respectively. LOD and LOQ were 40 and 120 ng/zone for (1) and 120 and 240 ng/zone for (2), respectively.
J. Ethnopharmacol. 236, 474-483 (2019). HPTLC of asiaticoside and madecassoside in Centella asiatica on silica gel with butanol - ethyl acetate - water 4:1:5. Detection by spraying with anisaldehyde-sulfuric acid reagent, followed by heating at 105 ºC for 5 min. Qualitative identification under UV light at 580 nm.
J. Ethnopharmacol. 229, 233-245 (2019). HPTLC of diarylheptanoid in the rhizomes of Alpinia officinarum on silica gel with chloroform - methanol - formic acid 85:20:2. Detection under UV light at 254 nm. The hRF value for diarylheptanoid was 90.
Phytochem. Anal. 30, 405-414 (2019). HPTLC fingerprint of 70 standard medicinal plants on silica gel with ethyl acetate – ethyl methyl ketone – formic acid 98% – water 5:3:1:1. Derivatization with anisaldehyde, Liebermann–Burchard, 3 % iron(III) chloride (FeCl3) and phosphomolybdic acid reagent. Detection before and after derivatization under visible light and UV light (254 and 366 nm). A similarity search algorithm based on color (RGB, HSV and Lab) information alone or together with hRF values was built to assess the fingerprinting of medicinal plants. The method showed better results than principal components analysis (PCA), classification and regression trees (CART) and partial least squares discriminant analysis (PLS‐DA).
J. Liq. Chromatogr. Relat. Technol. 30, 311-319 (2019). HPTLC of marker compounds in Porana sinensis on silica gel with ethyl acetate - methanol - formic acid 12:2:1. DPPH* scavenging activity was performed by spraying with 2.54 mM 2,2′‐diphenyl‐1‐picrylhydrazyl methanol solution. Xanthine oxidase inhibitory activity was detected by dipping into a xanthine oxidase staining solution [agar: 0.1 mg/mL; EDTA (ethylenediaminetetraacetic acid): 1 mM; dipotassium hydrogen phosphate/potassium dihydrogen phosphate: 50 mM; NBT (nitro blue tetrazolium): 0.22 mg/mL; xanthine oxidase: 68 mU/mL], followed by incubation for 10 min at 38 °C in an incubation chamber and dipped again in 3 mM solution of xanthine, followed by a second incubation for 20 min at 38° C.
Phytochem. Anal. 30, 332-345 (2019). TLC fingerprint of Musa paradisiaca fruits on silica gel with hexane - acetone 7:2. Detection by dipping into 5 % anisaldehyde sulfuric acid solution in methanol. Densitometric absorption measurement at 540 nm. To determine antioxidant activity, the plate was dipped into 0.05 mM DPPH* radical reagent solution in methanol and kept at room temperature in dark conditions for 30 min. Further analysis of zones by gas chromatography‐mass spectrometry.
Phytochem. Anal. 30, 679-686(2019). HPTLC-Acetylcholinesterase bioassay of cherimoya fruits on silica gel with the enzyme substrate 1‐naphthyl acetate (1.5 mg/mL). Enzymatic solution was sprayed (1 U/mL in 50 mM Tris–HCl buffers at pH 7.8), followed by incubation at 37 ºC for 10 min. A Fast Blue B salt aqueous solution (1.0 mg/mL), freshly prepared, was sprayed onto the plate to obtain a purple background. Further analysis by HPTLC-MS allowed the characterization of three potential AChE inhibitors: anonaine, glaucine and xylopine.
J. AOAC Int. 102, 776-780 (2019). HPTLC of sibutramine, phenolphthalein, and three PDE5 inhibitors (sildenafil, vardenafil and tadalafil), as well as caffeine, fluoxetine, theophylline, and acetaminophen as adulterants in weight loss products on silica gel with methyl tert-butyl ether – toluene – methanol 8:2:1. Densitometric absorption measurement at 225 nm. The hRF values of reference substances increased in the following order: fluoxetine, sildenafil, vardenafil, caffeine, theophylline, tadalafil, acetaminophen, phenolphthalein and sibutramine. The method was successfully used for the screening of 12 commercial products. Of those, nine products tested positive for at least one undeclared component.
