Abstract :
A new unusual sesquiterpene lactone, named amygdalactone, was isolated from the hulls of almond (Prunus amygdalus). Complete assignment of the proton and carbon chemical shifts for the new lactone was accomplished on the basis of high-resolution 1D and 2D NMR data. Amygdalactone represents a new class of sesquiterpene with cyclohexa[7,12-g]octalactone ring system. The cytotoxic activity of amygdalactone was determined.
