title: Three new bis-styryllactones from Goniothalamus cheliensis.
abstract: Three new bis-styryllactone analogues, goniolactones G-I (1-3), have been isolated from the root barks of Goniothalamus cheliensis. Their structures were established on the basis of extensive spectroscopic investigation including HR-ESI-MS and 2D NMR (HSQC, HMBC, (1)H-(1)H COSY, ROESY).
