Biological Activities
Athyrium distentifolium has demonstrated significant anthelmintic activity against the nematode Haemonchus contortus, a parasite commonly found in small ruminants. In recent studies, methanol extracts of this European fern were tested for their ability to impact both drug-susceptible and drug-resistant strains of the parasite. Specifically, at a concentration of 0.1 mg/mL, the extract effectively reduced the viability of female worms to 36.2%. This potential for medicinal use is bolstered by the fact that the extracts showed no toxicity in ovine liver tissue tests. As drug resistance and environmental contamination become growing concerns, such plant-based solutions offer an environmentally friendly alternative for treating helminthiasis.
Compounds
Conditions
Athyrium distentifolium serves as an effective treatment against the adult stages of the nematode parasite Haemonchus contortus. Research indicates that methanol extracts of this European fern significantly decrease the viability of both drug-susceptible and drug-resistant female worms. When applied at a concentration of 0.1 mg/mL, the extract reduced the viability of the ISE strain to 36.2% and the WR strain to 35.3%. This anthelmintic activity is supported by the presence of major chemical components such as quercetin, kaempferol, and luteolin within the plant. Such findings highlight the potential of this specific fern to combat helminthiasis in small ruminants as an environmentally friendly alternative to conventional drugs.
Preparations
Athyrium distentifolium is prepared as a methanol extract to investigate its potential medicinal properties. This specific plant extract was tested for its anthelmintic activity against the nematode Haemonchus contortus. During the study, the extract demonstrated effectiveness by significantly decreasing the viability of both drug-susceptible and drug-resistant female parasites. At a concentration of 0.1 mg/mL, the preparation reduced the viability of the ISE strain to 36.2% and the WR strain to 35.3%. The chemical analysis of such fern extracts identified various polyphenols, including quercetin and kaempferol, as major active components.
