【 摘 要 】

Asteraceae weeds are rich in chemicals that have biological and pharmaceutical activities. The aims of this work were to describe the phytochemistry and quantify the polyphenols in ethanol extracts from leaves of 12 species of Asteraceae weeds collected in Diamantina, Minas Gerais State, Brazil. The screening of Asteraceae extracts revealed the presence of tannins, steroids, triterpenes, anthocyanins, and flavonoids. The total phenolic content was high in extracts of Lychnophora ericoides (147.97 ± 2.66), Lepidaploa lilacina (141.11 ± 1.99), and Eremanthus elaeagnus (134.61 ± 7.81) and low in extracts of Lychnophora ramosissima (32.65 ± 0.70), and Lychnophora sp. (54.03 ± 0.73). Extracts of Asteraceae weeds from Diamantina could have potential for biological studies that are searching for new pesticides and drugs.
