Abstract

An emerging vegetable, ‘paccasassi’ (Crithmum maritimum L.), as a source of nutraceuticals: purification and chemical characterization of polar extracts Diletta Piatti1, Simone Angeloni1, Giovanni Caprioli1, Filippo Maggi1, Gianni Sagratini1, Lolita Arnoldi2 1 School of Pharmacy, University of Camerino, Via S.
