Abstract:
Two new compounds, goniothalesacetate (1) and goniothalesdiol A (2) together with goniodiol-7-monoacetate, goniodiol-8-monoacetate, leiocarpin C, liriodenine, griffithazanone A, 4-methyl-2,9,10-(2H)-1-azaanthracencetrione, velutinam and aristolactam BII were isolated and characterized from the stems of Goniothalamus amuyon. Structures of new compounds were determined by spectral analysis.
