Abstract: The plant activators such as D,L-β-aminobutyric acids can induce systemically acquired resiatance in the treated plants against the pathogen infection. Saccharide carboxylate compounds are known for their physiological and pharmaceutical importance. In order to investigate the synergic effect of the glucose and β-aminobutyric acid , eight new glycosyl esters of β-aminobutyric acid were synthesized with the reaction of 3-N-benzyloxycarbonyl-β-aminobutyric acid with acetylated glycosyl bromide or di-O-isopropyllidene-glucose. The structures were confirmed via elemental analysis and 1H NMR. Bioassay results indicate that several compounds show a better induced activity against pathogen infection than salicylic acid.

Key words: D,L-β-Aminobutyric acid, Glucosyl ester, Induced resistance, Bioactivity
