title: Investigation of dietary important components in selected red fleshed apples by GC-MS and LC-MS.
abstract: Three red-fleshed apple cultivars (Malus 'Geneva': GFV-03, Hungarian hybrid: GFV-04, Malus pumila Niedwetzkyana: GFV-05) were investigated for their chemical composition by sHS-SPME-GC-MS and HPLC-DAD-MS/MS analytical techniques. In cultivars GFV-03 and GFV-05 sesquiterpene α-farnesene were dominant while the alphatic esters were present mostly in traces. In GFV-04 - the new disease resistant advanced selection of the Hungarian apple breeding program - hexanol and hexyl 2-methylbutanoate were present in larger amounts while the amount of α-farnesene was lower than the other two cultivars. Using HPLC-DAD-MS/MS four phenolic acid derivatives, four anthocyanins, six flavonoids of quercetin derivatives and two dihydrochalcone phloretin glycosides were identified or characterized among the detected sixteen phenolic compounds.
