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

J. Liq. Chromatogr. Relat. Technol. 29, 1247-1256 (2006). TLC of MDMA (3,4-methyledioxymethamphetamine) and additives (magnesium stearate, aspirin, paracetamol, caffeine, glucose, citric acid) with acetonitrile - chloroform 1:1, chloroform - methanol 9:1 (best separation), acetonitrile - chloroform - ammonia 2:8:1, chloroform - methanol - ammonia 9:1:1, and chloroform - acetone - methanol - ammonia 10:8:1:1. Detection under UV 254 and 366 nm.
J.A.O.A.C. 67, 563-565 (1984). TLC of chloramphenicol on silica with ethyl acetate. Detection: 2 minutes exposure in jar containing solid calcium hypochlorite, 45 sec. in jar containing 37 % formaldehyde, spray lightly with aq. solution containing 1 % starch + 1 % KI. Detection limit: > 60 ng.
Shimadzu Hyoron, (Shimadzu Review) 45, 199-202 (1988). TLC on silica with different solvent systems. Detection by spraying with different reagents or under UV. Quantification by densitometry. Detection limit for glycyrrhizin, geniposide, capsaicine, kainic acid, atropine and scopolamine, 0.01-0.1 µg/spot.
Arzneim.-Forschung / Drug Res. 44, 469-471 (1994). HPTLC of flunitrazepam, trimipramine, carbamazepine, diclofenac on silica with 3 different solvent systems: 1. chloroform - acetone 85:15, 2. ethyl acetate - ethanol - NH3 100:10:3, 3. dichloromethane - acetone 12:1; examination under UV 366 nm; quantification by fluorodensitometry; recording of UV-spectra between 200 and 400 nm (absorbance).
J. Planar Chromatogr. 9, 280-281 (1996). HPTLC of heroin, opium, mandrax tabl., diazepam, oxazepam, nitrazepam, phenobarbitone, and caffeine on silica with chloroform - ethanol 9:1. Detection after drying for 5 min at 100°C by spraying with a 1:1 mixture of 1% aqueous solutions of cupric chloride and potassium ferricyanide resulting in a dark brown spot for heroin. The reagent does not give positive reaction to the usually occurring adulterants as barbiturates, benzodiazepines, methaqualone, and caffeine, etc. Sensitivity: about 1 mg of heroin/spot.
J. Liq. Chrom. & Rel. Technol. 22, 161-171 (1999). OPLC of 82 basic drugs and metabolites on HPTLC silica gel with trichloroethylene - methyl ethyl ketone - n-butanol - acetic acid - water 17:8:25:6:4 and butyl acetate - ethanol - tripropylamine - water 340:37:20:3. Densitometry. The system can be used in the screening for drugs in autopsy urine samples, utilizing automated identification by hRf/UV library search.
Leg. Med. 8, 184-187 (2006). HPTLC on silica gel of cocaine urine samples submitted to solid phase extraction prior to derivatization (methylation) with diazomethane. For methylation samples were mixed with 100 µL of a solution freshly prepared by distillation of 2.14 g N-methyl-N-nitroso-p-toluenesulfonamide with 10 mL potassium hydroxide 96 % in ethanol and 30 mL ethyl ether, and kept at room temperature for 1 min to convert benzoylecgonine to cocaine. Development over 7 cm in a saturated chamber with ethyl acetate – cyclo hexane – ammonia 250:100:1. Detection by spraying with Dragendorff reagent (10 mL of 40 % m/v potassium iodide in water; 10 mL of 1 N solution of bismuth nitrate in glacial acetic acid; 80 mL of 10 % v/v sulfuric acid water solution; 2 g of resublimed iodine). The technique is capable to discriminate cocaine from interfering substances such as nicotine, caffeine and even cocaethylene in urine samples. The limit of detection was 100 ng of cocaine.
