Abstract

3′-Formylalpinumisoflavone (1), and 2-(1-hydroxy-1-methylethyl)-3-hydroxy-2,3-dihydrofuranoalpinumisoflavone (2) were isolated from the stem of Derris scandens along with five known isoflavones. The two new compounds were characterised by extensive use of high resolution NMR spectroscopy. Senegalensin (3) was reported here for the first time in D. scandens.
