The root material of Derris scandens collected from two localities in India has yielded five natural products whose structures have been examined mainly by physical methods in association with a few partial syntheses and degradations. The extractives include the isoflavones, warangalone (scandenone)(VIIa) and chandalone (XIV), and three 3-aryl-4-hydroxycoumarins, Ionchocarpic acid (II), scandenin (III), and Ionchocarpenin (X), The results of the examination of these extractives are compared with earlier studies and the biogenetic significance of the natural co-occurrence of isoflavones and 3-aryl-4-hydroxycoumarins is discussed.
