摘要

A new isoflavone was obstained from the medicinal herb Amorpha fruticosa. It was elucidated asbenzopyran-12-one,1,4,10,11-tetrahydro-6'-[8'-(hydroxymethyl)ethenyl]-2,3-dimethoxy-8'-O-beta-D-glucopyranosyl-O-alpha-D-arabinoside by spectroscopic methods including UV, IR, 1D NMR and 2D NMR techniques. And the activity against acetaminophen-induced hepatotoxicity of this compound was also studied, and found this compound can protect liver obviously from hepatotoxicity induced by acetaminophen (AAP).
