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.
