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:

with the reference of protostemonine. J. Planar Chromatogr. 28, 448-451 (2015). HPTLC of protostemonine in Stemona sessilifolia on silica gel with ammonium hydroxide solution (25 %, v/v) – acetone – ethyl acetate – cyclohexane 1:4:4:6. Detection by spraying with diluted bismuth potassium iodide solution followed by drying at room temperature and spraying with 5 % sodium nitrite in 70 % ethanol solution. The hRF value for protostemonine was 30. The intermediate precision was below 2 % (n=5).

J. Planar Chromatogr. 30, 199-204 (2017). HPTLC of sophoridine (1), matrine (2), and sophocarpine (3) in S. alopecuroides on silica gel with toluene – acetone – methanol – ammonia – water 80:30:2:5:80. Detection by spraying with bismuth potassium iodide reagent (1:1 mixture of 0.85 g of bismuth nitrate with 10 mL of glacial acetic acid and 40 mL of water, heated for dissolution, and 8 g of potassium iodide in 30 mL of water). Quantitative determination by absorbance measurement at 500 nm. The hRF values for (1) to (3) were 22, 56 and 65, respectively. Linearity ranged from 415-2491 ng/zone for (1), 424-2547 ng/zone for (2) and 410-2460 ng/zone for (3). The intermediate precision was <5 % (n=3). Recovery rate ranged from 97.8 to 98.9 % for (1), 98.3 to 100.9 % for (2) and 99.1 to 101.2 % for (3).
