摘要

A MeOH extract from the stem bark of?Artocarpus?gomezianus?showed DPPH free radical scavenging activity. Bio-assay guided fractionation of this MeOH extract led to the isolation of four flavonoids, namely artonin E (1), cycloartobiloxanthone (2), artobiloxanthone (3) and (+)-catechin (4). These compounds were shown to possess recognizable DPPH free radical scavenging activity and appreciable inhibitory effect on nitric oxide production?in murine macrophage-like cells.
