Summary: | N-(15,16-Dihydroxylinoleoyl)-glutamine (
1
) and
N-(15,16-epoxylinoleoyl)-glutamine (
2
) and were identified in the regurgitant of lepidopteran larvae (
Spodoptera exigua and
Spodoptera frugiperda) by LC–MS. After methanolysis and derivatisation with MSTFA, the positions of the hydroxy groups of
1
were identified by GC–MS. The structures of both conjugates were confirmed by synthesis.
The
N-acyl glutamines
1
and
2
were isolated from the regurgitant of the lepidopteran larvae
Spodoptera exigua and
Spodoptera frugiperda. The structures were confirmed by synthesis. |
