Abstract: The plant activators such as salicylic acid and acetosalicylic act as a regulary molecue in plants which can stimulate the biosynthesis of phytoalexin to inhibit the growth of micobial patogens. In order to investigate the synergic effect of the glucose and salicylic acid, ten new glycosyl esters of salicylic acid were synthesized by the reaction of salicylic acid and acetosalicylic acid with acetylated glycosyl bromide. The structures were confirmed by elemental analysis and 1H NMR. The 1H NMR spectra showed that they were β-isomer. Bioassay results indicate that several compounds show a better induced activity against pathogen infection than salicylic acid.

Key words: Salicylic acid, Acetosalicylic acid , Acetyl glycosyl esters, Induced resistance, Bioactivity
