Última Phytochemistry and quantification of polyphenols in extracts of the Asteraceae weeds from Diamantina, Minas Gerais state, Brazil Planta Daninha Petacci,F.; Tavares,W.S.; Freitas,S.S.; Teles,A.M.; Serrão,J.E.; Zanuncio,J.C. 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...

(Arecaceae), an endemic and threatened palm of the Espinhaço Mountains, Brazil Acta Botanica Miola,Deise Tatiane Bueno; Fernandes,G. Wilson. ABSTRACTSyagrus glaucescens is an endemic palm found in the rupestrian grasslands of the Espinhaço Mountains in southeastern Brazil. It is highly associated with quartzitic soils and exhibits strong intra-specific morphological variation in the different areas where it occurs. Allometric traits were used to verify whether there are any significant differences in the morphological traits between populations of this species located in two distinct areas. In the region of the Serra do Cipó individuals exhibit decumbent stems whereas on the Diamantina Plateau stems are straight and perpendicular to the ground. Soil quality was related to plant morphological traits to test the hypothesis that allometric variation is influenced by soil nutritional differences....
