Abstract

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-dihydroxy-4′-methoxy-3′-(3-hydroxy-3-methylbut-1-enyl)-5′-(3-methylbut-2-enyl)flavanone (trivial name, burttinone). In addition, seven known compounds were identified. Structures were determined on the basis of spectroscopic evidence.

Two new flavanones, abyssinone V-4′-methyl ether and burttinone (3) were isolated from the stem bark of Erythrina burttii and characterized on the basis of spectroscopic evidence.

    Citation Excerpt :

    Erythrina sacleuxii Hua is a red-flowered 9–24 m tall tree endemic to Kenya and Tanzania (Gillett et al., 1971). Previous studies on the roots and stem barks of Kenyan specimens of E. sacleuxii yielded flavones, isoflavones, isoflavanones, pterocarpans, and isoflav-3-enes (Yenesew et al., 1998a, 1998b; Yenesew et al., 2000; Andayi et al., 2006; Ombito et al., 2018). Herein, the isolation and structural elucidation of two new isoflavones, together with seven known compounds from the twigs of the Kenyan specimens of E. sacleuxii is reported.
