Antioxidant phenolics from Broussonetia papyrifera fruits

Abstract

Fractionation of the EtOH extract from the fruits of Broussonetia papyrifera led to the isolation of 15 phenolic compounds (1–15). Their structures were identified using spectroscopic methods. Among these compounds, 1 and 2 are new and 3–15 were isolated from this plant for the first time. Antioxidant activities of compounds 2–15 against H₂O₂-induced injury in SY5Y cells and 1,1-diphenyl-2-picrylhydrazyl radical scavenging activities were evaluated.

Keywords:
