Glucosinolates in wild and cultivated Brassica montana Pourret (Brassicaceae) from southern France.

The glucosinolate (GL) profiles of wild and cultivated Brassica montana Pourret (seed, stem, leaf, root) from southern France were established using LC-MS analysis. In this investigation we have confirmed the presence of 9 known GLs: but-3-enyl- (1), prop-2-enyl- (2), pent-4-enyl- (3), (2R)-2-hydroxybut-3-enyl- (4), 4-hydroxyindol-3-ylmethyl- (5), 4-(methylsulfinyl)butyl- (6), 4-(methylsulfanyl)butyl- (7), 1-methoxyindol-3-ylmethyl- (8), and indol-3-ylmethyl (9) GL. In addition, we tentatively identified for the first time the presence in the plant of 1-methylpropyl GL (10) in all plant parts. In addition, we have pointed out differences in GL profiles between plant organs and between wild and cultivated B. montana.
