Three new compounds from the barks of Morus nigra

Abstract

Three new compounds including two flavonoids and a new 2-phenylbenzofuran, named morunigrols A–C (1–3), together with three known compounds albafuran A (4), albafuran B (5), and mulberrofuran L (6), have been isolated from the barks of Morus nigra. Their structures have been elucidated by spectroscopic methods.
