(2005). Analysis and quantification of flavonoidic compounds from Portuguese olive (Olea europeae L.) leaf cultivars. Natural Product Research. ISSN 1478-6427. 19:2, p. 189-1951478-6427http://hdl.handle.net/10198/728Twenty three samples of 18 Portuguese olive leaf cultivars were analysed by a reversed-phase HPLC/DAD procedure and eight flavonoidic compounds were identified and quantified (luteolin 7,40-O-diglucoside, luteolin 7-O-glucoside, rutin, apigenin 7-O-rutinoside, luteolin 40-O-glucoside, luteolin, apigenin and diosmetin). Luteolin 7,40-O-diglucoside and luteolin 40-O-glucoside were identified by HPLC/DAD/MS/MS – ESI. The studied olive leaf samples showed a common phenolic pattern, in which luteolin 40-O-glucoside was almost always the major compoundengOlea europaea L.Olive leavesOlive cultivarsHPLC-DAD/MS/MS/ESIFlavonoidsjournal article10.1080/14786410410001704886
