Metabolism of Sinapine in Mustard Plants. I. Degradation of Sinapine into Sinapic Acid & Choline

“…Sinapic acid was prepared from sinapilne thiocyanate by the method of Schultz (10 To assay for sinapine in the extract a 5 ml aliquot of the extract was transferred to a 15 ml tapered centrifuge tube which was chilled in an ice bath for a few minutes. One ml of a 50 % saturated water solution of Reinecke salt (this solution should not be older than 2 days) was then added and the tube was allowed to stand in an ice bath for 1 hour.…”

“…This new natural product was namiied sinapine, an(l in 1897 Gadamer (4) propased its structure (fig 1) to be that of the choline ester of sinapic aci(l. Later studies (10,11) showed that siniapine is wi(lelv (listributedl among members of the family Cruciferae.This compoun(l appeared to be of bioclhelmlical in- To assay for sinapine in the extract a 5 ml aliquot of the extract was transferred to a 15 ml tapered centrifuge tube which was chilled in an ice bath for a few minutes.

Cardamine sp. – A Review on Its Chemical and Biological Profiles

“…In Cardamine amara L., (1-methylpropyl)GL (1) was identified in the aerial parts [8] and in the seeds [9] [10]. PC Analysis of a C. amara seed extract, carried out by Danielak and Borkowski, indicated the presence of a GL.…”

“…More recently, Agerbirk et al found a number of desulfoGLs originating from 1 -3,5, 9, 10, 13, 15, 17, 22, [3-(hydroxymethyl)pentyl]GL(25), an unidentified isomer of 25, and [(4-methoxyphenyl)methyl]GL(26) in the upper leaf of the flowering shoot of C. pratensis[26]. Furthermore, the authors determined the presence of the desulfoGLs of 2, 3, 9, 10, 13, 22, and 26 in the rosette leaf, as well as 1, 2,5,9,10,13,15,17,18,22, and 26 in the roots. In addition, commercially obtained C. pratensis contained 1) 5,9,17,18,22,25, and an unidentified isomer of 25 in the rosette leaf; 2) 5,9,17,18,22,25, an unidentified isomer of 25, and [(1,4-dimethoxy-1H-indol-3-yl)methyl]GL(27) in the roots; 3) 9, 17, 18, 25, and an unidentified isomer of 25 in the seeds[26].Finally, one unidentified GL was detected, by PC, in the seed extract of Cardamine rivularis Schur[11].2.1.2.…”
