Compounds Isolated from <i>Paepalanthus</i> spp. (Eriocaulaceae) and Their Evaluation in Antimicrobial, Cytotoxic, and Antiviral Assays.

ABSTRACT: and belong to the Eriocaulaceae family. According to the literature, secondary metabolites isolated in Paepalanthus have interesting biological activities. This research aimed to isolate constituents from the capitula of the mentioned species and to evaluate their cytotoxic, antimicrobial, and antiviral activities. Through maceration and several types of separation procedures, the crude extracts were produced, and the structures of constituents were identified mostly by nuclear magnetic resonance. Cytotoxic and antimicrobial activities were evaluated by 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide and 2,3,5-triphenyl-2H-tetrazolium chloride methods, respectively, while antiviral activity was evaluated by enzymatic and phenotypic assays. Two flavonoids were iso
