Identification
Biological Activities
Athyrium distentifolium has demonstrated significant anthelmintic activity against the nematode parasite Haemonchus contortus. In recent studies, methanol extracts of this fern were tested for their ability to reduce the viability of both drug-susceptible and drug-resistant adult worms. Specifically, at a concentration of 0.1 mg/mL, the extract successfully decreased the viability of female parasites in both tested strains. This botanical approach offers a potentially environmentally friendly alternative to traditional pharmaceuticals, which often face challenges regarding drug resistance and environmental contamination. The efficacy of these ferns is further supported by the presence of key bioactive components such as quercetin and kaempferol.
Compounds
Conditions
Athyrium species are utilized in traditional medicine for their anthelmintic properties to treat various ailments. Research has also demonstrated that these plants possess significant anti-HIV potential. Furthermore, certain species exhibit effective anti-inflammatory characteristics. The plants also demonstrate useful antimicrobial activities in biological studies. Finally, the antioxidant potential of Athyrium is a key biological property linked to its chemical composition.
Preparations
Athyrium is prepared as methanol extracts to investigate its potential anthelmintic properties. Specifically, the research focuses on the methanol extract of Athyrium distentifolium to evaluate its effects on the nematode Haemonchus contortus. These extracts were tested against both drug-susceptible and drug-resistant strains of the parasite. The results demonstrated that the Athyrium methanol extract significantly decreased the viability of female worms. This preparation method allowed for the identification of major polyphenolic components within the plant material.
