Asteraceae family: a review of its allelopathic potential and the case of Acmella oleracea and Sphagneticola trilobata

Abstract Asteraceae family is as an interesting target for researching natural alternatives crop protection. Many species from this grow weeds, and some of them can influence the development other by allelopathy phenomenon. This paper aimed to review literature main genera with allelopathic or phytotoxic potential, well classes secondary metabolites present in responsible such activity. Artemisia, Ambrosia, Bellis, Bidens, Helianthus Tagetes were identified Among family, terpenes, polyacetylenes, saponins, sesquiterpene lactones, phenolic acids flavonoids described inhibiting species. In addition, potential Acmella oleracea Sphagneticola trilobata against weeds Calopogonium mucunoides. Ipomoea purpurea was first time. At 0.2 mg/mL, crude extract fractions A. inhibited above 60% C. mucunoides root growth. Hydroalcoholic S. trilobata, except hexane, significantly affected I. growth, ranging 38 ± 14% 59 8% inhibitory effect at different concentrations (0.19 mg/mL 1.13 mg/mL).
