Potassium β- d-glucopyranosyl 11-hydroxyjasmonate, a leaf-closing substance of Albizzia julibrissin Durazz

Abstract

Potassium β- d-glucopyranosyl 11-hydroxyjasmonate ( 1) was isolated as a leaf-closing substance of a nyctinastic plant, Albizzia julibrissin Durazz. Compound 1 was quite effective for the leaf-closing of A. julibrissin at 2×10 −5 M, and was proved to be a trans-isomer of β- d-glucopyranosyl tuberonic acid previously isolated from potato as a tuber-inducing stimulus.
