title: Long-chain Glucosinolates from Arabis turrita: Enzymatic and Non-enzymatic Degradations.
abstract: C8-C10 methylsulfinylalkyl glucosinolates (GLs), and C8-C10 methylsulfonylalkyl GLs were identified in the seed of Arabis turrita L. by HPLC-MS/ESI analysis of intact GLs. Enzymatic (with myrosinase) and non-enzymatic (thermal at 100 degrees C, and chemical at different pH) hydrolyses were performed and the volatile isolates were analyzed by GC-MS. Only the enzymatic and chemical (pH 10) degradations produced volatiles which are originating from GL degradation. GC-MS analysis showed the presence of long-chain olefinic isothiocyanates (ITCs) along with other the long-chain thiofunctionalized GL breakdown products.
