From the stem bark of Erythrina burttii, two new flavanones were isolated and characterised as 5,7 dihydroxy-4'-methoxy-3',5'-di-(3-methylbut-2-enyl)flavanone (trivial name, abyssinone V-4'-methyl ether) and 5•7-dihydr•xy-4'-meth•xy-y-(3-hydr•xy-3-methy•but-•-eny•)-5'-(3-methy•but-2-eny•)•avan•ne (trivial name, burttinone). In addition, seven known compounds were identified. Structures were determined on the basis of spectroscopic evidence. © 1998 Published by Elsevier Science Ltd. All rights reserved
