Abstract
Phytochemical and Antioxidant Activity of Asplenium Species (Spleenworts) Extracts from Northern Districts of Iraq
Highlights
The spleenworts family (Aspleniaceae) includes just one very large genus: Asplenium, a cosmopolitan and important genus of the Aspleniaceae family, order Polypodiales, comprises 650 species distributed among the world [1]
Absorbance values converted into the percentage antioxidant activity (AA %) using the following equation: AA % = (Ac- As)/Acx100.Where Ac is the absorbance of the control and as is the absorbance of the sample
The results showed that A. scolopendrium contains five flavonoid compounds: querctin, rutin, kaempferol, kaempferol-3-O-glycoside and leutolin but Asplenium trichomanes contains six flavonoids Table 5
Summary
The spleenworts family (Aspleniaceae) includes just one very large genus: Asplenium, a cosmopolitan and important genus of the Aspleniaceae family, order Polypodiales, comprises 650 species distributed among the world [1]. Phytochemical investigations on the ferns have led to characterization many secondary metabolites [2]. (commonly known as maidenhair spleenworts), the fern grows in aggregate form, the laevs are long , gradually tapering towards the tip, they bear long narrow sori to both sides of midrib, widespread in tropics and mountainous regions prefers acidic rocks such as sandston and cliffs [4]. In the ten last years , much attention has been devoted to ferns as potential sources of natural antioxidants and several Asplenium species have been evaluated for their antioxidant potential [8]. To the knowledge, this is the first investigation focus on flavonoids quantitatively and qualitatively of Asplenium species from North of Iraq
