ENEA-IRIS Open Archive è l’archivio della produzione scientifica dell'ENEA, realizzato con l'obiettivo di raccogliere, catalogare e rendere facilmente accessibili in rete i risultati della ricerca. Gli autori dell’ENEA provvedono a depositare le proprie pubblicazioni (articoli su rivista, presentazioni a congressi, report, ecc.). In particolare, quelle finanziate dalla Commissione Europea nell’ambito del programma H2020 (che prevede il deposito obbligatorio in un Repository), una volta caricate, vengono automaticamente importate dal portale europeo OpenAIRE. È possibile inserire, o importare direttamente dalle banche dati previste, le informazioni descrittive del documento e anche allegare, ove consentito dalla normativa sul diritto d'autore, il testo completo della pubblicazione.

ENEA-IRIS Open Archive utilizza la piattaforma IRIS (Institutional Research Information System) sviluppata da CINECA.

Freshness and authenticity of Chinese and Italian royal jelly samples were investigated by means of HPLC determination of furosine and (E)-10-hydroxy-2- decenoic acid. In addition, High Resolution Magic Angle Spinning Nuclear Magnetic Resonance (HR-MAS NMR) spectroscopy was used to determine the metabolic profile of the same royal jelly samples. water-soluble metabolites such as amino acids and sugars as well as fatty acids were identified in the same experiment. A combined approach including NMR analytical profile together with HPLC measured markers was used to discriminate between Italian and Chinese samples by means of Principal Component Analysis. © IBRA 2013.

Abstract

Freshness and authenticity of Chinese and Italian royal jelly samples were investigated by means of HPLC determination of furosine and (E)-10-hydroxy-2- decenoic acid. In addition, High Resolution Magic Angle Spinning Nuclear Magnetic Resonance (HR-MAS NMR) spectroscopy was used to determine the metabolic profile of the same royal jelly samples. water-soluble metabolites such as amino acids and sugars as well as fatty acids were identified in the same experiment. A combined approach including NMR analytical profile together with HPLC measured markers was used to discriminate between Italian and Chinese samples by means of Principal Component Analysis. © IBRA 2013.
