Glucosinolate hydrolysis products in the crucifer Barbarea vulgaris include a thiazolidine-2-one from a specific phenolic isomer as well as oxazolidine-2-thiones

A new type of glucosinolate hydrolysis product, a thiazolidine-2-one, was formed from a phenolic glucosinolate in one chemotype of Barbarea vulgaris. In both chemotypes, oxazolidine-2-thiones were also major products. The new glucosinolate product was formed in vitro with myrosinase and during autolysis.
