3′-Formyl-2′,4′,6′-Trihydroxydihydrochalcone From Psidium Acutangulum

Twig and leaf extracts of the Peruvian plant Psidium acutangulum were shown to have antifungal properties against the fungi Rhizoctonia solani, Helminthosporium teres and Pythium ultimum. Chemical investigation of these extracts resulted in the isolation of the new compound, 3′-formyl-2′,4′,6′-trihydroxychalcone, which demonstrated activity against the fungi R. solani and H. teres. © 1991
