The growth improvement of aCardamine pratensis cell suspension can be obtained by the addition of casein hydrolysate to the medium. This component can be replaced by the same concentration of glutamine. Moreover on two cell suspensions,C. pratensis andSilene alba, this glutamine effect appears only when the medium has a phosphorus deficiency. Consequently, casein hydrolysate effectiveness would be due to its high concentration of glutamine and its contribution would balance the shortage of this amino acid synthesis when the medium has a phosphorus deficiency.
The aerial parts of Boronia ternata var. elongata from western Australia has yielded three new 2-acyl-4(1H)-quinolinone alkaloids, characterised as 2-n-pentyl-4(1H)-quinolinone, 1-methyl-2-n-pentyl-4(1H)-quinolinone and 1-methyl-2-(1 xi-methyl)-propyl-4(1H)-quinolinone, as well as known alkaloids of this class and a furoquinoline alkaloid. Boronia alulata, from northeast Queensland, also yielded 2-n-pentyl-4(1H)-quinolinone together with the known 2-n-propyl-4(1H)-quinolinone. Both species are assigned to Boronia section Valvatae which, alone among the sections of Boronia, appears to be characterised by the presence of alkaloids.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
