Structure Elucidation of A New 2-Arylbenzofuran Isolated from Sesbania grandiflora

Some new naturally phenolic compounds have been successfully isolated from the ethyl acetate extract of the stem bark of Sesbania grandiflora. We reported herein the isolation and identification of a new 2-arylbenzofuran, namely sesbagrandiflorain A from the EtOAc extract of S. grandiflora stem bark. The structure elucidation of sesbagrandiflorain A was performed using one- and two-dimensional nuclear magnetic resonance, ultraviolet and infrared spectroscopy, and electrospray ionization time-of-flight mass spectrometry. This compound was found for the first time from Sesbania grandiflora. Keywords: 2-arylbenzofuran, sesbagrandiflorain A, Sesbania grandiflora
