Fourteen compounds were isolated by column chromatography from the ethyl acetate extract of the seeds of Brassica campestris. Their structures were elucidated by physicochemical properties and spectroscopic data analysis. The isolated compounds were respectively identified as (5Z,7E)-4,
In this study we investigated the role of indole-3-acetonitrile, indole-3-carbinol, indole and tryptophan in the formation of N-nitroso compounds in green cabbage extracts. Green cabbage extracts were separated by gel permeation chromatography. Fractions were treated with nitrite, tested for
The metabolism of the cruciferous phytoalexins brassinin and cyclobrassinin, and the related compounds indole-3-carboxaldehyde, glucobrassicin, and indole-3-acetaldoxime was investigated in various plant tissues of Brassica juncea and B. rapa. Metabolic studies with brassinin showed that stems of B.
