Two new flavonoids from Erythrina eriotriocha.

: In addition to the known compounds erythinasinate [1] and abyssinone V [2], two new flavonoids were isolated from the CHCl3 extract of the stem bark of Erythrina eriotriocha and characterized by spectroscopic techniques as 3'-prenylnaringenin [3] and 2'-hydroxy-5'-methoxybiochanin A [4].
