BIOLOGICALLY ACTIVE COMPOUNDS FROM CHILEAN PROPOLIS

A propolis sample from the western Andean slopes of the Maule Region, Chile, showed free radical scavenging activity and inhibited the enzyme xanthine oxidase "in vitro". Six flavonoids were isolated as the main active constituents of the sample. 5,7-dihydroxyflavone 4, 3,5,7-trihydroxyfla...
