Phytosociological research on aquatic and marsh vegetation was conducted in Rzeszów Reservoir (SE Poland): 134 relevés according to the Braun-Blanquet method were collected there in 2016 and compared to 91 relevés published in 1994 (225 relevés in total). Changes in vegetation type, diversity measures, species composition, and Ellenberg Indicator Values (EIVs) for light, moisture, reaction, and nitrogen were analysed. Over the 22 years (1994–2016), the greatest changes were noted in communities of the classes Lemnetea and Potametea and the alliance Salicion albae. The long-term observations demonstrated the disappearance of 14 phytocoenoses and the occurrence of 12 new ones. An expansion of marsh communities (Typhetum latifoliae, Typhetum angustifoliae, Glycerietum maximae, Leersietum oryzoidis) was noted, causing a decline of several species and vegetation types. According to canonical correspondence analysis (CCA), four environmental variables (light, moisture, nitrogen, and pH) were related to plant distribution. The strong disturbances reflected in intensive eutrophication were due to human activity, which is the main factor shaping the ecological succession and overgrowing of the reservoir.

Urban water bodies are an important asset in terms of climate change. The accompanying vegetation is an integral part of the waterside space system and a source of ecosystem services and disservices. The composition of greenery in waterside spaces should therefore be preceded by detailed research. This research would be the basis for the development of recommendations for enhancement of the positive impact of vegetation on humans and minimisation of its negative effect. The aim of the study was to identify ecosystem services and disservices of vegetation in the four most important waterside recreation spaces in the city of Rzeszów, Poland, and to develop plant composition guidelines. A detailed inventory of vegetation and aerobiological monitoring of the presence of airborne allergenic pollen grains and fungal spores were carried out. Next, the ecosystem services and disservices of the vegetation were determined based on literature data and on our expert judgement. Additionally, a counting of the number of visitors to waterside areas was conducted. All these steps were used to develop recommendations for shaping the vegetation of study areas. The results of the investigations show that the boulevards along the artificial lake function completely differently than other investigated places as the area resembles an urban park, and the water is not the main attraction in this space. The vegetation of the boulevards and the nearby gravel-pit bathing area has mostly a spontaneous character and offers the widest range of ecosystem services and disservices. The management of the vegetation should focus on its health-enhancing values. The vegetation growing near the outdoor swimming pools has been designed by man. Nevertheless, it requires recomposing and is targeted specifically at the enhancement of the visual attractiveness. Additionally, there is a need for planting compact deciduous trees that will provide shade at the multi-media fountain.

A wide range of plant-derived preparations have been used against skin inflammatory disorders and as wound healing agents in traditional medicine. The purpose of the study was to determine the antioxidant activity of aqueous and 70% ethanolic extracts from eleven species of plants traditionally used in Poland to treat inflammatory skin diseases. The ability of extracts to scavenge 2,2-diphenyl-1-picrylhydrazyl radical (DPPH), hydrogen peroxide (H2O2), and superoxide anion (O2 • −), was studied. In non-cellular studies, an analysis of the anti-inflammatory effect on the activity of enzymes, such as hyaluronidase (HYAL) and lipoxygenase (LOX), was also performed. The chemical profiles of the most active extracts were achieved by applying the UHPLC-DAD-MSn method, and the sum of polyphenols in all tested extracts was determined by the colorimetric method with the Folin–Ciocalteu reagent. The scope of the extracts’ influence on enzyme activity was significantly lower than their antioxidant activity. All extracts have shown high activity in free radical scavenging against DPPH. The ethanolic extracts have shown high potential to scavenge H2O2. The study of composition showed that the main components of the tested extracts were flavonoids, such as luteolin, apigenin, kaempferol, and quercetin derivatives, as well as caffeoylquinic acids, caffeic acid, and its conjugates.

Arctium lappa is a weed used in traditional medicine in the treatment of skin inflammation and digestive tract diseases. Arctium tomentosum is used in folk medicine interchangeably with Arctium lappa and, according to European Medicines Agency (EMA) monography, provides an equal source of Arctii radix (Bardanae radix), despite the small amount of research confirming its activity and chemical composition. The aim of the study was the comparison of the anti-lipoxygenase and the antioxidant activity, scavenging of 2,2-diphenyl-1-picrylhydrazyl (DPPH), superoxide anion (O2•−), and hydrogen peroxide (H2O2), of 70 % (v/v) ethanolic extracts from the aerial parts and the roots of Arctium lappa and Arctium tomentosum. In the tested extracts, the total polyphenols content and the chemical composition, analyzed with the HPLC–DAD–MSn method, were also compared. The extracts were characterized by strong antioxidant properties, but their ability to inhibit lipoxygenase activity was rather weak. A correlation between the content of polyphenolic compounds and antioxidant activity was observed. The extracts from A. lappa plant materials scavenged reactive oxygen species more strongly than the extracts from A. tomentosum plant materials. Moreover, the extracts from A. lappa plant materials were characterized by the statistically significantly higher content of polyphenolic compounds.

Linden trees are a source of food products called lime flowers (Tiliae flos), traditionally used in the form of infusion for the treatment of feverish colds and coughs. Lime flowers should include flowers of Tilia cordata Mill, T.x europaea L., and T. platyphyllos Scop. or a mixture of these. The aim of current research was to establish a fast, sensitive HPTLC (high-performance thin-layer chromatography) method that would allow the differentiation of material obtained from five species of lime occurring in Europe. The fingerprints for distinguishing these species were established, as well as a key for identification based on a visual evaluation of chromatograms. The results obtained were also subjected to chemometric analyses. It was shown that each species contains characteristic compounds i.e. linarin that can be used for their identification. The method developed can, in theory, be introduced for the quality control or authentication of linden flowers on the European market.

Lime flowers are traditionally used as medicinal plants. According to the Pharmacopeia Europaea, only three species of Tilia are admitted as source species. However, so far, no methods enabling the discrimination between these three species and other species of Tilia occurring in Europe have been established. It is also not clear whether the chemical composition of extracts from lime flowers differs between source species. Here, we describe a comprehensive validated UHPLC-DAD-MS/MS method to distinguish the five most important Tilia species in Europe based on phytochemical analyses of extracts prepared from their flowers. Forty-two phenolics were detected in the analyzed extracts and twenty-one of them were quantified using a validated method. A chemometric analysis revealed significant differences between the investigated species. Based on the chemical profile of their extracts, we provide a dichotomous key for the identification of Tiliae flos source species.

Linden flower is a wildly used plant material among patients in the treatment of common cold symptoms and mucosa inflammations. However, the structure and bioactivity of flavan-3-ol derivatives present in infusions from flowers of Tilia cordata have not been studied so far. The aim of current study was to isolate and identify main procyanidins present in the flowers of small-leaved lime and to evaluate their influence on the inflammatory response of human neutrophils ex vivo. The chemical structure of isolated compounds was established by 1D and 2D NMR experiments. The bioactivity of obtained compounds was tested in human neutrophils model. Cytotoxicity and influence of compounds on apoptosis was established by flow cytometry. The levels of produced cytokines were established ELISA after stimulation with lipopolysaccharide (LPS). The inhibition of the production of reactive oxygen species was checked by luminol dependent chemiluminescence method after N-formylmethionyl-leucyl-phenylalanine (f-MLP) induction. The phytochemical work resulted in the isolation of 10 compounds. Compounds were identified as oligomeric procyanidins and their precursor epicatechin. The potential anti-inflammatory activity of compounds was evaluated in the concentration range 5-20 μM. All compounds were able to decrease the production of ROS from f-MLP-stimulated neutrophils. Most of compounds were able to inhibit the LPS-induced release of IL-8. Some trimeric and tetrameric derivatives were also able to decrease the production of MIP-1β. Obtained results partially support the traditional usage of infusion from lime flowers in the treatment of symptoms of inflammation and irritation of mucosa in common cold, pharyngitis and tonsillitis.

The aim of this study was to provide a phytosociological and ecological characterization of meadow communities in the Łąki w Komborni Natura 2000 site (SE Poland), assess the trends in their transformation, and indicate the major threats impacting on their conservation. The study was conducted in 2015–2016. Three types of meadow communities were distinguished (alliances Molinion, Arrhenatherion, Filipendulion), due to the absence of the species characteristic for associations. The species richness noted per relevé differed significantly between the types of meadows (Kruskal–Wallis test: H = 21.65, p < 0.05). The highest floristic biodiversity (H' = 2.99) was noted for the meadow patches classified as in the Molinion alliance and the lowest (H' = 2.50) was found for the patches from the Filipendulion alliance. Mean values of the ecological indicators (F, R, N) differed between the meadow communities. The greatest disparity was noted for the mean values of the soil moisture indicator (from 6.42 to 7.45). Patches classified in the Filipendulion alliance were developed on the wettest soil substratum, whereas the patches classified in the Arrhenatherion alliance were predominant on a relatively dry substratum. The abandonment of traditional management practices (grazing, mowing) has contributed to transformation of the Molinia meadows, disappearance of characteristic species and succession of shrubs. The Molinia meadow habitat should be conserved by improvement of protection measures (appropriate mowing regime and removal of biomass) to conserve a high species richness and the rare and protected plant species.

The paper presents characteristics of a meadow community with Trollius europaeus, threats posed to the community, and proposals for active protection thereof. The study was carried out in the “Łąki w Komborni” Natura 2000 site (PLH 180042) in the Podkarpacie Province (SE Poland). In 2015, 20 relevés were taken with the Braun-Blanquet method and they are presented in a synthetic table. Additionally, the number of clumps, the number of flowering shoots per clump, and the height of flowering shoots were determined. The community with Trollius europaeus was classified into the alliance Molinion caeruleae with Selinum carvifolia, Galium boreale, Succisa pratensis, Betonica officinalis, Gladiolus imbricatus, and Carex tomentosa as characteristic species. Scrub species, in particular Filipendula ulmaria, had a substantial share, which indicated long-term abandonment of land use. The community also comprised rush species (Carex gracilis, Phragmites australis) and a numerous group of species from the order Arrhenatheretalia (e.g. Geranium pratense, Alchemilla monticola, Galium mollugo, Arrhenatherum elatius) and the class Molinio-Arrhenatheretea (e.g. Lathyrus pratensis, Alopecurus pratensis, Ranunculus acris, Poa pratensis). Abandonment of extensive land use leading to progressive secondary succession is the major threat to phytocoenoses with Trollius europaeus. To preserve meadows with Trollius europaeus, active protection involving mowing and removal of biomass is recommended.

Tiliae flos commonly known as linden flower is a popular medicinal plant material used in the form of infusion to treat symptoms of common cold such as sore throat, cough and fever. Tiliae flos has a monograph in the European Pharmacopoeia 8.0 which defines lime flower as flowers obtained from T. plathyphyllos L., T. cordata Mill. and T. x vulgaris Hayne. Although linden flower is a well-known traditional drug the reports on its chemical composition are limited. The aim of the study was to develop a UHPLC-DAD-MS method for the comparison of chemical composition of Tiliae flos obtained from two of the most common species T. cordata and T. platyphyllos occurring in Europe in order to find any potential chemotaxonomic markers. Seven samples of T. cordata and T. platyphyllos were collected in different regions of Poland in 2014 and 2015. Water-methanol (50:50) extracts were prepared. The UHPLC separation was carried out with Kinetex XB-C18 150 mm x 2.1 mm x 1.7 µm. Identification of compounds was based on the analysis of their UV-Vis and MS fragmentation spectra. The results confirmed that both Tilia species are a rich source of flavonoids and flavan-3-ol derivatives. Among flavonoids only quercetin and kaemferol glycosides were detected. Rutin and isoquercitrin were dominating flavonoids. The presence of epicatechin and dimeric procyanidins (B1, B2 and C1) was also confirmed. The careful comparison of investigated samples indicated some qualitative differences in the chemical composition of flowers obtained from the two chosen species. Extracts from T. platyphyllos contained quercetin di-O-rhamnoside, kaempferol O-rhamnoside-O-pentoside and kaempferol O-rhamnoside-O-hexoside. These compounds were absent in all investigated extracts of T. cordata. In addition, T. cordata extracts exclusively contained an unidentified O-rhamnohexoside (m/z= 591) eluting at the retention time of approx. 46.7 min. These compounds can be considered as potential chemotaxonomic markers for both species. Acknowledgements: This work was supported by the Polish National Science Centre project nr 2015/17/D/NZ7/02641.

In the present study we investigated the chemical composition of extracts prepared from aerial parts of Oenothera paradoxa Hudziok and Oenothera biennis L. and their antioxidative and anti-inflammatory activities. Ultra high pressure liquid chromatography (UHPLC)-DAD-MS/MS studies showed that both extracts contain a wide variety of polyphenols (39 identified constituents) among which macrocyclic ellagitannin turned out to be the main constituent. During the in vitro studies, using noncellular models, both extracts scavenged reactive oxygen species (ROS) in a concentration-dependent manner, and the lowest SC50 values were obtained for O2– and H2O2. Both extracts inhibited ROS production by stimulated human neutrophils. The stronger activity in the case of formyl-met-leu-phenylalanine stimulation suggests that both extracts may act through the receptor-dependent pathway. O. paradoxa extract and O. biennis extract exhibited anti-inflammatory activity by the inhibition of hyaluronidase and lipoxygenase in a concentration-dependent manner. The stronger activity of O.biennis extract toward lipoxygenase may be explained by its higher oenothein B content.

The research on segetal flora and agricultural ecosystems has gained special importance in recent years, since they are an important element in biodiversity conservation. An evaluation of the status of the segetal flora was made on the basis of a study conducted in the period 1998–2002 in crop fields of four municipalities located in the Strug River valley in Podkarpackie Voivodeship. This research was carried out in root and cereal crops. Total species richness and the average number of species per relevé were determined in this study. In determining species diversity of the communities, the Shannon-Wiener diversity index (H’) was used. In cereal crops, the community Vicietum tetraspermae typicum was characterized by the greatest species richness (109 species), while Vicietum tetraspermae consolidetosum showed the lowest richness (57 species). In root crops, the association Oxalido-Chenopodietum polyspermi exhibited the greatest richness (78 species), whereas Galinsogo-Setarietum typicum the lowest richness (53 species). In the cereal communities, a total 149 of weed species were recorded, while in the root communities their total number was 97. The values of the Shannon-Wiener diversity index (H’) ranged from 3.10 to 2.42. The phytocoenoses Oxalido-Chenopodietum polyspermi, Vicietum tetraspermae typicum, and Vicietum tetraspermae, the variant with Vicia grandiflora, were characterized by the highest values of the Shannon-Wiener diversity index (H’), whereas the association Galinsogo-Setarietum typicum and the impoverished communities from the alliance Aperion spicae-venti showed the lowest values.
