In this contribution, new chromosome data obtained on material collected in Italy are presented. It includes counts for Centaurea aegusae , Hieracium racemosum subsp. lucanum, H. australe australe, Lysimachia arvensis arvensis, Micromeria graeca graeca, and M. consentina.

background and objectives: iran owns a rich and prestigious heritage of medicinal herbs but the majority of these plants have not yet undergone chemical, pharmacological and toxicological studies. in the present study some species form northern parts of iran were evaluated for cytotoxicity. methods: sixteen medicinal plants were extracted with methanol and screened for their cytotoxic activitie...

Building natural classifications for genera with complex morphological variations such as Centaurea needs the support of molecular analysis and knowledge character diversification. Here we use parsimony Bayesian analyses nuclear ribosomal ITS sequences to gain insight into sectional relationships evolution in sections Chartolepis, Cheirolepis, Cynaroides, Grosheimia, Microlophus, Paraphysis, Ph...

Hexane, chloroform, ethyl acetate and ethanolic extracts of the aerial parts of Centaurea austro-anatolica Hub.-Mor. (Asteraceae) were evaluated against microorganisms, including multiresistant bacteria, using a paper disc diffusion method. The chloroform extract exhibited significant antibacterial activity toward all bacteria tested. The chemical composition of the chloroform extract was deter...

" Agapeta zoegana oviposited significantly more on rosette and one-stem plants. " 2 plants had significantly greater A. zoegana larval density than 4 plants. " Significant correlation between the number of larvae infesting plant roots and Centaurea stoebe root diameter. " Cyphocleonus achates fed more frequently on multiple-stem 4 plants. " Arion lusitanicus had a strong feeding preference for ...
