the anti inflammatory modulatory role of Solidago chilensis meyen in the murine model of the air pouch
Journal of Pharmacy and Pharmacology, 2008Co-Authors: Rafael De Liz, Silvana Virginia Gagliotti Vigil, Stella Goulart, Maria Izabel, Goularte Moritz, Eloir Paulo Schenkel, Tânia Silvia FrodeAbstract:The aim of this study was to investigate the anti-inflammatory efficacy of an aqueous extract (AE), and its butanolic (BuOH) and aqueous residual (AR) fractions, derived from the rhizome of Solidago chilensis in inflammation caused by carrageenan in mice. Solidago chilensis Meyen rhizome was extracted using hot water at 90 degrees C under infusion. The extract was filtered and lyophilized. Part of the aqueous extract was fractionated with n-BuOH, resulting in butanolic (BuOH) and aqueous residual (AR) fractions. Adult Swiss mice were used in the in-vivo experiments. We evaluated the effect of rhizome aqueous extract of Solidago chilensis and these two derived fractions on the inflammation induced by carrageenan in the mouse model of the air pouch. The aqueous extract and its derived fractions significantly inhibited leucocytes, neutrophils, exudation, myeloperoxidase and adenosine deaminase activity, as well as nitric oxide, interleukin-1 beta (IL-1beta), neutrophil chemokine (KC) and tumour necrosis factor-alpha (TNF-alpha) levels (P 0.05). These results indicate that Solidago chilensis has a significant anti-inflammatory action on acute inflammatory responses and that its inhibitory activity may be due not only to the inhibition of proinflammatory mediators, but also to the inhibition of leucocyte infiltration.

anti inflammatory evaluation of Solidago chilensis meyen in a murine model of pleurisy
Journal of Ethnopharmacology, 2007Co-Authors: Stella Goulart, Eloir Paulo Schenkel, Maria Izabel G Moritz, Karen Luise Lang, Tânia Silvia FrodeAbstract:Abstract The aim of this study was to investigate the anti-inflammatory effects and the mechanism of action of the aqueous extracts obtained from rhizomes, leaves and inflorescences of Solidago chilensis in the mouse model of pleurisy. The extracts were prepared by infusion and were lyophilized. Results The aqueous extracts of rhizomes, leaves or inflorescences inhibited leukocytes, neutrophils and exudation ( P P P P P P Conclusion Solidago chilensis aqueous extracts from leaves, inflorescences and rhizomes demonstrated an important anti-inflammatory effect, inhibiting cells in the inflammation caused by carrageenan. In addition, the rhizomes aqueous extract and its derived fractions also decreased pro-inflammatory mediators release into the site of the inflammatory process. The rhizomes aqueous extract and the butanolic fraction showed more evident anti-inflammatory actions.

Molecular evidence for hybridization between invasive Solidago canadensis and native S. virgaurea
Biological Invasions, 2016Co-Authors: Artur Pliszko, Joanna Zalewska-gałoszAbstract:Hybridization between alien and native species is biologically very important and could lead to genetic erosion of native taxa. Solidago × niederederi was discovered over a century ago in Austria and described by Khek as a natural hybrid between the alien (nowadays regarded also as invasive) S. canadensis and native S. virgaurea . Although interspecific hybridization in the genus Solidago is considered to be relatively common, hybrid nature of S . × niederederi has not been independently proven using molecular tools, to date. Because proper identification of the parentage for the hybrid Solidago individuals solely based on morphological features can be misleading, in this paper we report an additive polymorphism pattern expressed in the ITS sequences obtained from individuals representing S. × niederederi , and confirm the previous hypothesis that the parental species of this hybrid are S . canadensis and S . virgaurea . Additionally, based on variability at the cp DNA rpl 32- trn L locus, we showed that in natural populations hybridization occurs in both directions.

neotypification of Solidago niederederi asteraceae
Phytotaxa, 2015Co-Authors: Artur PliszkoAbstract:Solidago × niederederi Khek (1905: 22) (Asteraceae) was described by Khek (1905) as a natural hybrid between S . canadensis Linnaeus (1753: 878) and S . virgaurea Linnaeus (1753: 880). The hybrid was discovered by Niedereder in the area of Stoder (Austria) in the beginning of the twentieth century. It is morphologically more or less intermediate between the presumed parents, especially in characters such as capitula size, leaf shape and venation (Khek 1905, Nilsson 1976, Karpavicienė & Radusienė 2015). Moreover, it is characterized by reduced pollen viability, and produces only very few well-developed achenes (Nilsson 1976, Migdalek et al . 2014, Karpavicienė & Radusienė 2015). According to the protologue (Khek 1905) the pappus is absent in the hybrid (“Pappus fehlend”), however, I noticed the pappus in all examined generative specimens of the hybrid from Poland. The parental species of S . × niederederi belong to different taxonomical sections: S . canadensis is a member of S. sect. Unilaterales Don in Loudon (1830: 348), and S . virgaurea is a member of S. sect. Solidago Linnaeus (1753: 878) (Nesom 1993). The hybrid has been reported from several countries in Europe: Austria, the United Kingdom, Denmark, Sweden, Norway, Germany, Poland, Lithuania, and Russia (Nilsson 1976, Burton 1980, Sunding 1989, Mayorov et al . 2012, Pliszko 2013 and literature cited therein, Karpavicienė & Radusienė 2015). It is usually found in anthropogenic habitats together with both parental species, and its presence emphasizes the invasive character of S . canadensis (Pliszko 2013).

a new locality of Solidago niederederi khek asteraceae in poland
Biodiversity: Research and Conservation, 2013Co-Authors: Artur PliszkoAbstract:Solidago ×niederederi is a natural hybrid between S. canadensis and S. virgaurea, which occurs sporadically in synanthropic habitats together with the parental species. The hybrid was reported from seven countries in Central and Northern Europe and its presence emphasizes the invasive character of S. canadensis. A new locality of the hybrid was found in Mieruniszki village in the Zachodniosuwalskie Lakeland in NE Poland in 2011 (ATPOL square: FB06). Solidago ×niederederi grew on fallow land, at the edge of planted birchen shrubbery and its population comprised two small clumps. Current data suggest that the hybrid is a casual alien in the Polish flora, however, it has the potential to become established by clonal growth or restricted sexual reproduction.
