Xenognosin (1) is a modified flavonoid isolated from gum tragacanth, and it stands as the first natural host recognition substance for parasitic angiosperms.Xenognosin (1) was synthesized by converting umbelliferone (2) to the key aldehyde 6 which was tre
PISUM SATIVUM STRESS METABOLITES: TWO CINNAMYLPHENOLS AND A 2'-METHOXYCHALCONE

An HPLC study of copper(II) chloride treated Pisum sativum has shown that the cynnamylphenols obtustyrene and xenognosin as well as the chalcone 4,4'-dihydroxy-2'-methoxychalcone accumulate as de novo metabolites in the stressed plant.This chalcone has not previously been identified from a plant source.The biosynthetic and stress response relationships of these compounds are discussed. - Key Word Index: Pisum sativum; Leguminosae; garden pea; stress metabolism; cinnamylphenols; 2'-methoxychalcone; HPLC.
