Identification
Biological Activities
Dryopteris affinis subsp. cambrensis has demonstrated significant anthelmintic activity against the nematode Haemonchus contortus. In recent studies, methanol extracts of this fern were found to be highly effective at decreasing the viability of both drug-susceptible and drug-resistant female parasites. Specifically, at a concentration of 0.1 mg/mL, the extract reduced female viability to 23.3% in the resistant strain compared to untreated controls. This biological activity is likely driven by major polyphenol components such as quercetin, kaempferol, and luteolin found within the plant. Utilizing such medicinal ferns offers a promising, environmentally friendly alternative to traditional pharmaceuticals that often face issues with drug resistance and environmental contamination.
Compounds
Conditions
Dryopteris affinis subsp. cambrensis demonstrates significant anthelmintic activity against the adult stages of the nematode parasite Haemonchus contortus. When tested at a concentration of 0.1 mg/mL, this specific fern extract effectively reduced the viability of female worms from both drug-susceptible and drug-resistant strains. Specifically, it decreased the viability of the ISE strain to 32.9% and the WR strain to 23.3% compared to untreated controls. The effectiveness of this plant relationship is attributed to major chemical components such as quercetin, kaempferol, and luteolin. Furthermore, the treatment proved to be safe for the host, as the extracts exhibited no toxicity in ovine liver tissue.
Preparations
Dryopteris affinis subsp. cambrensis is prepared as a methanol extract to investigate its potential anthelmintic properties. This specific plant extract was tested for its efficacy against both drug-susceptible and drug-resistant strains of the nematode Haemonchus contortus. In the study, the preparation was found to be effective at reducing the viability of female parasites. At a concentration of 0.1 mg/mL, the extract significantly decreased the survival rates of the target organisms compared to untreated controls. Furthermore, the preparation showed no signs of toxicity when tested against ovine liver slices.
