Biological Activities
Eurybia macrophylla stands out as a significant subject in recent studies exploring the ethnobotanical legacy of Native American medicinal plants. Researchers focused on members of the Asteraceae family from the southeastern United States to investigate their potential therapeutic properties. By extracting essential oils through hydrodistillation, the team was able to analyze the chemical compositions of various wild-growing species. Specifically, the essential oil of E. macrophylla demonstrated notable antifungal activity during in-vitro testing. These findings highlight the plant's potential role in addressing fungal pathogens such as Aspergillus niger, Candida albicans, and Cryptococcus neoformans.
Compounds
Conditions
Preparations
Eurybia macrophylla was one of several native plants selected for the extraction of its volatile compounds. The aerial parts of this specific species were collected from wild-growing plants located in north Alabama. Researchers utilized a hydrodistillation process to obtain the essential oils from the collected plant material. These extracted oils were then analyzed using gas chromatography-mass spectrometry to determine their chemical compositions. This preparation allowed for the subsequent testing of the plant's essential oils against various fungal pathogens.
