Abstract:Four compounds were isolated from leaves of Goniothalamus griffithii. Their structures were determined by means of spectral method. Three of them were identified as goniodiol monoacetate (Il ), β- sitosterol (lII) and β- daucosterol (IV). One of them was new, whose struc-ture was elucidated as cycloat- 23-ene 16β, 25-diol named as griffithine A (I).
