Cardiopetalolactone: A Novel Styryllactone from Goniothalamus cardiopetalus

A new styryllactone namely cardiopetalolactone was isolated and characterized from the stem bark extract of Goniothalamus cardiopetalus (Annonaceae) together with two known lactones altholactone and goniopypyrone. The structure and stereochemistry of the new compound was determined on the basis of 2...

Description
Summary:A new styryllactone namely cardiopetalolactone was isolated and characterized from the stem bark extract of Goniothalamus cardiopetalus (Annonaceae) together with two known lactones altholactone and goniopypyrone. The structure and stereochemistry of the new compound was determined on the basis of 2D NMR experiments, NOE difference spectroscopy and the Mosher ester technique.
