Hi all,

i do hope that this is the right board i pose this question - otherwhise, my apologies to this.

I am looking for the chemical compound of "Safran" which colors yellow to orange. I still could not find any hints about the name of the compound that causes this color.

Does anyone of you know about it or has a website or pdf.document about it ?

with all respect

However, saffron's golden yellow-orange colour is primarily the result of α-crocin. This crocin is trans-crocetin di-(β-D-gentiobiosyl) ester (systematic (IUPAC) name: 8,8-diapo-8,8-carotenoic acid).


Crocin - that's it ... the most close solution (wikipedia) seems to be the best solution :D

Special thanks 12AX7 :)
