N2 - Investigation of the constituents of Phyllanthus virgatus has led to the isolation of five new compounds, including a norlignan, 2-(3,4- methylenedioxybenzyl)-4-(3,4-methylenedioxyphenyl)-3-butyne-1,2-diol named virgatyne (1); a hydrolyzable tannin, virganin (2); and three flavonoid sulfonates, galangin-8-sulfonate (4), galangin-3-O-β-D-glucoside-8- sulfonate (5), and kaempferol-8-sulfonate (6). Their structures were established by spectral and chemical methods.
