Abstract
In recent research for bioactive substances of Arabidopsis thaliana , seven new oxylipins named arabidopsides A- G were isolated from the aerial parts of this plant. Arabidopsides A- G were monogalactosyl diacylglycerides or digalactosyl diacylglycerides containing 12-oxophytodienoic acid and/or dinor-oxophytodienoic acid which were known as precursors of jasmonic acid (JA) and have received much attention because they play important roles in regulation of developmental and defense gene expression of plants as JA and methyl jasmonate. On the other hand, it is known that plant volatile compounds like C6 aldehydes, alcohols, and acetates are released from plants in response to mechanical wounding and herbivore attack. In this research, we investigated the effect of volatile compounds as potent inducers for triggering accumulations of arabidopsides A , B, E, and G in mature leaves of A. thaliana . In addition, volatile compounds-induced arabidopsides were not detected in the some JA- signaling and JA- synthesis mutants.
