Abstract:
In this paper we aimed to establish the content in polyphenolic compounds (flavones and polyphenolcarboxylic acids) in the soft extract of Elaeagnus angustifolia L. (oleaster) young branches, using high-performance liquid chromatography coupled with mass spectrometry (HPLC-MS). The comparative analysis of the chromatograms obtained before and after hydrolysis showed a complex composition. We identified through MS an unknown compound noted as X, which is a rhamnetol or isorhamnetol heteroside because the pick disappears after hydrolysis..
