摘      要：In the present study,17 flavonoids,including 9 prenylated isoflavones,4 isoflavones,3 flavanones and 1 flavone,were isolated from the twigs and leaves of Erythrina *** NMR spectroscopic means and comparision with the data in the leteratures,their structures were elucidated to be euchrenone b10(1),senegalensin(2),erythrinin C(3),scandenone(4),osajin(5),alpinum isoflavone(6),isoerysenegalensein E(7),erysenegalensein E(8),diprenylgenistein(9),abyssinone V(10),abyssinone V 4′-methyl ether(11),4′,7-dihydroxyflavanone(12),3′,5,7-trihydroxy-4′-methoxyisoflavone(13),2′,4′,5,7-tetrahydroxyisoflavone(14),genistein(15),daidzein(16),and apigenin(17).Except for compounds 1,4-7,and 9-10,other compounds were isolated from *** for the first time.
