The bioassay-guided fractionation of the antifungal dichloromethane extract from the roots of Vernonanthura tweedieana (Baker) H. Rob. (Asteraceae), using an agar overlay bioautographic method, allowed the isolation of one active sesquiterpene (1), identified as
We aimed to establish a phytochemical analysis of the crude extracts and performed GC-MS of the essential oils (EOs) of Eugenia uniflora L. (Myrtaceae) and Asteraceae species Baccharis dracunculifolia DC, Matricaria chamomilla L. and Vernonia polyanthes Less, as well as determining their
