Conclusions
1. When DL-[2−14C] tryptophan, sodium [2−14C] pyrotartrate, sodium [14/C]-formate, and universally labeled L-[14C] glutamic acid were introduced through the root system intoCarex brevicollis DC, active brevicolline was obtained.
2. Tryptophan and sodium pyrotartrate are precursors of the β-carboline moiety of the brevicolline molecule, and sodium formate is a precursor of the N-methyl grouping.
3. The introduction of universally labeled L-glutamic acid does not lead to an unambiguous indication of the role of this precursor in the biosynthesis of brevicolline.
