Plant chemistryTwo prenylated flavanones from stem bark of Erythrina burttii
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.

2020, Arabian Journal of ChemistryCitation 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.
