Fig. 1.
HPLC chromatograms showing the desulfo-glucosinolate profile of seed samples from the four I. indigoticaaccessions.
The GL acronyms identify the following glucosinolates:
PRO = progoitrin;
epi-PRO = epi-progoitrin;
GNA = gluconapin;
4-OHGBS = 4-OH glucobrassicin;
GBS = glucobrassicin;
4-OMeGBS = 4-OMe glucobrassicin;
GIT/epi-GIT = glucoisatisin/epiglucoisatisin;
SIN I.S. = internal standard sinigrin.
