From: Development of an efficient glucosinolate extraction method
The cold extraction method yields less glucoraphasatin in R. sativus stems relative to the ISO 9167-1 (boiling methanol) extraction method (n = 4). Values normalised to the ISO method results. Error bars represent standard error. Asterisks represent significant difference from the ISO 9167-1 (boiling methanol) method (paired t test, p < 0.05)
