Abstract

6-Tuliposide A {6-O-(4-hydroxy-α-methylenebutyryl)-D-glucopyranose} was isolated from thunberg spiraea (Spiraea thunbergii) leaves. Acid-hydrolysis of this compound generated tulipalin A (α-methylene-γ-butyrolactone). This compound is thus considered as a precursor of insecticidal tulipalin A.

Keywords: 6-tuliposide A {6-O-(4-hydroxy-α-methylenebutyryl)-D-glucopyranose}; insecticidal activity; thunberg spiraea (Spiraea thunbergii); α-methylene-γ-butyrolactone (tulipalin A).
