Three members of the tribe Gnaphalieae and six members of the tribe Inuleae (Asteraceae) were analyzed for their exudate flavonoids. Whereas some species exhibit rather trivial flavonoids, others produce rare compounds. Spectral data of rare flavonoids are reported and their structural identification is discussed. 6-Oxygenation of flavonols is a common feature of two Inula species and Pulicaria...

Pulicaria is a genus of flowering plant in the Asteraceae family. It contains over 100 species. In this study the crude extract was prepared from the fresh leaves of P. glutinosa and further fractionated into three solvent to solvent fractions. The zebrafish (Danio rerio) embryos were treated with these extracts to explore the developmental toxicity. The crude extract did not show any significa...

Nine eriophyoid mites, including two new species and five new records, from Iran are described and illustrated. They are Aceria acroptiloni Shevchenko & Kacalev, 1974, rec. n. on Rhaponticum repens (L.) Hidalgo (Asteraceae); Aceria anthocoptes (Nalepa, 1892), rec. n. on Cirsium arvense (L.) Scop. (Asteraceae); Aceria lactucae (Canestrini, 1893), rec. n. on Lactuca virosa L. (Asteraceae); Aceria...

Phosphorus (P) is essential for growth of all organisms, and P content correlated with in most taxa. Although was initially considered to be a trait fixed at the species level, there growing evidence considerable intraspecific variation. Selection on such variation can thus alter rates which fluxes through food webs. Nevertheless, prior work describing sources extent were not genetically explic...
