Three new bis-styryllactones from Goniothalamus cheliensis

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, 1H–1H COSY, ROESY).
