Asplenium ceterach L. (syn. Ceterach officinarum Willd.) or rustyback fern is a plant species traditionally
used in Mediterranean countries as an expectorant, diuretic, against spleen complaints, kidney stones
and hemorrhoids. Phytochemical analysis of gametophytes and sporophytes of A. ceterach was performed, followed by comparative analysis of phenolic composition and the antioxidant properties of the
extracts (scavenging capacities against ABTS•+ and DPPH•). Totally 16 phenolic compounds belonging
to the classes of phenolic acids (hydroxybenzoic and hydroxycynnamic acids), flavonoids (flavan-3-ols,
flavonols), and xanthones were identified using UHPLC/DAD/–HESI-MS/MS analysis. Different phenolics’
composition of the two phases of the life cycle of this fern was observed which significantly determined
their radical scavenging activities. In sporophytes of A. ceterach considerably high amounts of
chlorogenic acid were found (~21 μg 100 mg-1 fresh weight), while xanthones were the most abundant
in gametophytes (mangiferin glucoside, reaching 2.54 μg 100 mg-1 fresh weight), recommending this fern
species as a valuable source of bioactive compounds.
