Abstract
This study aimed to compare the chemical composition of Morus nigra leaves extracts, obtained by maceration, accelerated solvent (ASE) and supercritical fluid extraction (SFE) under different extraction conditions. With regards to chemical composition, mainly phenolic acids and flavonoids were identified. HPLC–ESI–QTOF–MS allowed the identification of 13 new compounds reported in M. nigra leaves for the first time. ASE as a fast, green and innovative approach, seems to be the best choice for extracting compounds of different polarities within the shortest extraction time. The present study also highlights the potential application of M. nigra extracts as constituents of new added-value formulations.
