Leaves of Eucalyptus nitens (Deane &Maiden)Maiden were sampled during establishment of seedlings that were deprived of nutrients or fertilised at planting. Extracts were analysed for polyphenolic compounds using high pressure liquid chromatography (HPLC)in conjunction with UV diode array and electrospray ionisation mass spectrometry (ESI-MS)with negative ion detection as well as direct MS injection. The presence of quercetin, rutin, sideroxylonal A and B and penta-galloylglucose were confirmed by comparison with standards. Other galloylglucoses were identified by first principles. Galloylglucoses comprised about 75
