Abstract
The isolation of three antifungal pterocarpans from Pisum sativum epicotyls infected with Fusarium solani f. sp. pisi is described. By a combination of spectroscopic and degradative techniques the compounds were identified as 4-hydroxy-2,3,9-trimethoxy-(1), 3-hydroxy-2,9-dimethoxy-(2), and 2,3,9-trimethoxy-pterocarpan (3).
