pure glucosinolate sample?

[koenraad.tierens at agr.kuleuven.ac.be]

Dear netters,

Has anybody pure glucosinolate samples (glucoraphanin and/or glucoerucin) who
is possibly willing to share a very small amount with me, or knows where I
could order something like this?
It could be very helpful for me to compare this in a final step of GC-MS
characterization of different components in my Arabidopsis leaf extract...!

thanks for any info
