Analysis and quantification of flavonoidic compounds from Portuguese olive (Olea europaea L.) leaf cultivars.
Twenty 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 7,4'-O-diglucoside, luteolin 7-O-glucoside, rutin, apigenin 7-O-rutinoside, luteolin 4'-O-glucoside, luteolin, apigenin and diosmetin). Luteolin 7,4'-O-diglucoside and luteolin 4'-O-glucoside were identified by HPLC/DAD/MS/MS - ESI. The studied olive leaf samples showed a common phenolic pattern, in which luteolin 4'-O-glucoside was almost always the major compound.
