| Abstract | Apart from certain amino acids none of the nitrogenous intermediates involved in the biosynthesis of mustard oil glucosides have, untl now, been determined. Results consistent with the hypothesis — amino acids → aldehyde oximes → mustard oil glucosides — are presented for glucotropaeolin and gluconasturtin.
Administration of dl-[2-¹⁴C]phenylalanine and [1-¹⁴C]phenylacetaldehyde oxime to Tropaeolum majus L. shoots resulted in a greater incorporation of the tracer from the latter into the aglycone moiety of glucotropaeolin; incorporation of ¹⁴C from phenylacetaldehyde oxime into the aglycone was without randomization. Radioactive phenylacetaldehyde oxime was isolated from T. majus shoots which were fed dl-[2-¹⁴C]phenylalanine.
The extent of conversion of ¹⁴C into the aglycone of gluconasturtin was similar when 3-phenyl[1-¹⁴C]propionaldehyde oxime and dl-2-amino-4-phenyl[2-¹⁴C]butyric acid were fed to Nasturtium officinale R. Br. There was no randomization of labelled carbon in gluconasturtin aglycone derived from 3-phenylpropionaldehyde oxime. |
