Zusammenfassung

The chemopreventive chalcone xanthohumol (Xh) has been reported to decrease xanthine oxidase (XOD) catalysed formation of formazan from nitroblue tetrazolium (NBT) and is discussed as a potent scavenger of superoxide. Re-evaluation of the scavenging capacity indicated that Xh disturbed detection of superoxide with NBT, in case of an insufficient NBT/Xh ratio. Xh lacked superoxide scavenging ...
