摘　　要：Two new phenanthrenoid dimers, named dijuncuenins A （1） and B （2）, were isolated from the ethanolic extract of the whole plant of Juncus effusus. Their structures were determined by 1D and 2D NMR spectroscopic analysis and mass spectrometry. The plausible biosynthetic pathways of compounds 1 and 2 were proposed.Two new phenanthrenoid dimers, named dijuncuenins A （1） and B （2）, were isolated from the ethanolic extract of the whole plant of Juncus effusus.
