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:

Biomed. Chromatogr. 20 (2), 151-153 (2005). TLC of the four principal triterpenoid components of Centella asiatica on silica gel plates with the combination of ethyl acetate and methanol. Detection by spraying with anisaldehyde solution, followed by heating at 100 °C for 5 min. Evaluation under white light. The developed method is a modification of the method described in the European Pharmacopoeia (5th edn). Confirmation of the separated compounds by MALDI-TOF mass spectrometry.
J. Planar Chromatogr. 20, 197-202 (2007). HPTLC of guggulsterone E and Z on silica gel prewashed with methanol with petroleum ether - ethyl acetate - formic acid 30:10:1 in a twin-trough chamber saturated for 20 min. Detection and densitometric scanning at 254 nm.
iNDIAN dRUGs 44(8), 632 (2007). TLC, HPTLC and NMR spectroscopic methods are reported for identification and characterization of aloin isolated from Kumariasava and Aloe vera. TLC and HPTLC of chloroform extracts on silica gel with chloroform - ethyl acetate 3:1. Detection under UV 366 nm. The hRf value of aloin was 84.
J. Planar Chromatogr. 21, 119-123 (2008). TLC of aqueous Senna and Tilia extracts with sennoside A and B as standards on silica gel after immersion in acetonitrile - water 17:3, with 2-propanol - ethyl acetate - water 9:9:7 (for Senna extracts) and 2-butanone - ethyl acetate - formic acid - water 3:5:1:1. Detection under UV 254 nm. Although quantitative analysis was not performed, peak areas served for comparative evaluation.
Chromatographi 68 (1-2), 129-133 (2008). Description of a simple, rapid, specific and sensitive method for the quantitative estimation of mevalonic acid in leaves of Artemisia annua, Psorelia corylifolia, Vinca rosea, Withania somnifera and Barleria proinites. TLC of leaf extracts on silica gel with benzene - acetone 3:2 which involved conversion of mevalonic acid to its lactone, mevalonolactone. Detection by treatment with anisaldeyde reagent. Quantitative determination of mevalonolactone by absorbance measurement at 600 nm. Linearity was between 100 and 500 ng per spot. Recovery (by standard addition) was higher than 98 % for mevalonolactone. The limit of detection was 50 ng per spot.
J. AOAC Int. 91, 1179-1185 (2008). HPTLC of harmine, harmaline, vasicine, and vasicinone on silica gel with ethyl acetate - methanol - ammonia 70:10:3 in a twin-trough chamber at 25 °C and 40 % relative humidity. Quantitative determination by absorbance measurement at 366 nm for harmine and harmaline, at 292 nm for vasicine, and at 233 nm for vasicinone.
Ind. J. of Pharma Sci. 70(6), 847-851 (2008). HPTLC of apigenin in segregated parts (leaves, stems, flowers and fruits) of Turnera aphrodisiaca on silica gel with toluene - ethyl acetate 1:4. Quantitative determination by absorbance measurement at 336 nm. Flowers were found to contain maximum amount of apigenin whereas leaves contained the least. Apigenin contents in methanolic extracts of aerial plant parts were fourteen times lower than in acid hydrolyzed methanolic extracts, indicating the presence of most of apigenin in glycosidic form. The plant material collected in September showed maximum contents of apigenin.
Phytochem. Anal. 18, 209-212 (2007). Separation of extracts of Solanum diflorum and Setaria parviflora by TLC on silica gel, cellulose, and RP-18 and by HPTLC on cyano and diol phase with hexane - ethyl acetate 1:1 and n-butanol - formic acid - water 5:1:4 (upper phase). Detection after distribution of ß-glucuronidase staining solution (52.5 mg agar and 0.9 mL 0.5 % iron(III) chloride solution). After solidification of the staining solution, the TLC plate was incubated for 120 min at 37 °C and immersed in a 0.2 % solution of esculin. Autography showed enzyme inhibition zones with hRf of 14 (Solanum diflorum) and 46 (Setaria parviflora).
