title: Cardiobutanolide, a styryllactone from Goniothalamus cardiopetalus.
abstract: A styryllactone namely cardiobutanolide was isolated from the stem bark of Goniothalamus cardiopetalus together with four known styryllactones goniothalamin, goniodiol, goniofufurone, goniofupyrone and known acetogenins squamocin and an epimeric mixture of goniodonin and 34-epi-goniodonin. The structure of the new compound was elucidated on the basis of 1D and 2D NMR experiments and mass spectroscopic techniques.
