title: Lignans from Phyllanthus urinaria.
abstract: Chemical investigation on the aerial and the root parts of Phyllanthus urinaria L. culminated in the isolation of four lignans, namely 5-demethoxyniranthin, urinatetralin, dextrobursehernin, urinaligran, together with nine known lignans. Their structures, including the absolute stereochemistry, were elucidated by spectral analysis (NMR and CD) and chemical correlation.
