Jasmonates are formed from 12‐oxo‐10,15(Z)‐phytodienoic acid (12‐OPDA) in plants and also from 12‐oxo‐10‐phytoenoic acid (12‐OPEA) in fungi. Collision‐induced dissociation (CID) of [M‐H] generates characteristic product anions at m/z 165 [C11H17O]. Our goal was to investigate the structure and mode of formation of this anion by CID of 12‐OPDA, 12‐OPEA, and 12‐oxophytonoic acid (12‐OPA).

茉莉酸酯生物合成中环戊烯酮和环戊酮中间体的负离子模式电荷迁移断裂

茉莉酸盐是由植物中的12-氧-10,15 (Z)-植物二烯酸(12-OPDA)和真菌中的12-氧-10-植物烯酸(12-OPEA)形成的。[MH] -的碰撞诱导解离(CID)产生m / z 165 [C 11 H 17 O] -的特征产物阴离子。我们的目标是通过12-OPDA,12-OPEA和12-氧代苯甲酸(12-OPA)的CID研究该阴离子的结构和形成方式。
