Identification
Biological Activities
Dryopteris aemula 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 inhibit egg hatching and reduce adult viability in both drug-susceptible and drug-resistant strains. Specifically, a concentration of 0.2 mg/mL was found to inhibit egg hatching by 25% compared to the control group. Furthermore, the extract significantly decreased the viability of female parasites, even when facing drug-resistant strains. These promising results suggest that this plant could serve as an environmentally friendly alternative to traditional, hazardous chemical treatments.
Compounds
Conditions
Dryopteris aemula demonstrates significant anthelmintic potential against the nematode parasite Haemonchus contortus. Research indicates that extracts of this fern are effective at treating adult stages of the parasite, specifically reducing the viability of both drug-susceptible and drug-resistant female strains. Furthermore, the plant exhibits inhibitory effects on the life cycle by preventing the hatching of H. contortus eggs. At a concentration of 0.2 mg/mL, the extract specifically inhibits egg hatching by 25% compared to the control group. These dual capabilities against both adults and eggs highlight the medicinal utility of Dryopteris aemula in managing helminthiasis.
Preparations
Dryopteris aemula is prepared as a methanol extract to test its medicinal properties against parasites. This specific preparation was utilized in a study to evaluate its anthelmintic activity against the nematode Haemonchus contortus. Researchers found that the Dryopteris aemula extract inhibited egg hatching by 25% at a concentration of 0.2 mg/mL. Furthermore, the extract significantly decreased the viability of female worms from both drug-susceptible and drug-resistant strains. The chemical analysis of this prepared extract revealed several major polyphenolic components, including quercetin and kaempferol.
