One new dimeric 2-isopropenyl-2, 3-dihydrobenzofuran, eurycomalin A (1), was characterized from the methanol extract of the root of Eurycoma longifolia by the 1D and 2D spectral and chemical transformation studies. The reported structure of eurycomalide A (2) was revised through detail 2D spectral analyses.
