- Abstract:
- ... Achyrocline flaccida (Weinm) DC. essential oil was obtained by hydrodistillation of wild flowers from southern Brazil. We explored, for the first time, the phytochemical composition, toxicity, resistance to oxidative stress in Caenorhabditis elegans, and antimycobacterial activities of A. flaccida essential oil. Twenty-four compounds were identified by GC-FID-MS and the major constituents identifi ...
