Abstract/OtherAbstract:
|
Chemical investigation of the glandular trichome exudate from Silene gallica L. (Caryophyllaceae) resulted in isolation of 10 cyclic fatty acyl glycosides (gallicasides A-J). The cyclic structures were characterized by a glycosidic linkage of the glucose moiety to either the C-12 or the C-13 position of the octadecanoyl moiety, and by an ester linkage between the C-2 hydroxy group of the glucose moiety and the carboxyl group of the oxygenated octadecanoic acid. The structures of the cyclic fatty acyl glycosides were further distinguished from one another by acetylation and/or malonylation on the glucose moiety. Of these compounds, the 1,2'-cyclic ester of 12(R)-(6-O-acetyl-3-O-malonyl-beta-D-glucopyranosyloxy)octadecanoic acid (gallicaside J) was the most abundant (30.7%). These secondary metabolites were found specifically in the glandular trichome exudate rather than in other aerial parts. |
