“…No intraspecific differences were detected from TLC and HPLC patterns indicating that the composition of compounds is independent of environmental conditions. The influence of environmental factors on the amount of synthesized allelochemicals was beyond the scope of the current study, but other studies already demonstrated that light and nutrient supply as well as the presence of certain phytoplankton taxa influence the amount of allelopathic compounds exuded (reigoSa et al 1999;van donK & van de Bund 2002;Berger & Schagerl 2004;KuraShov et al 2014). We tested the potential of allelopathy in laboratory experiments, but for its impacts in natural environments, additional studies are needed.…”

“…Some other studies also suggested that low molecular weight substances could be allelopathically active (anthoni et al 1980;BanKova et al 2001;van donK & van de Bund 2002;lürling et al 2006;KuraShov et al 2014). BanKova et al (2001) identified some volatile compounds but did not test them separately for possible inhibitory effects.…”

“…This effect might be caused by higher concentrations of active compounds in the ice extracts than it would occur in situ. It is however a challenge to measure in situ concentrations due to the dilution in natural water bodies (groSS et al 2007;KuraShov et al 2014). Since laboratory experiments can hardly simulate the abiotic and biotic in situ parameters, there is an urgent need of additional field studies for testing allelopathic effects (groSS et al 2007).…”

“…It is a widely distributed phenomenon and found between terrestrial, e.g. walnut trees (erciSli et al 2005), and aquatic plants, e.g., (KuraShov et al 2014). Producing such alleochemicals is an advantageous strategy for being highly competitive.…”

Abstract:We investigated growth inhibitory effects of the stoneworts (Characeae) Chara aspera, C. globularis, C. rudis and C. tomentosa on the target organisms Chlorella vulgaris, Acutodesmus acuminatus (Chlorophyta), Synechococcus elongatus, S. leopoliensis (Cyanobacteria) and Aliivibrio fischeri (Proteobateria). Besides fresh Chara shoots, we tested dichloromethane, n-butanol and methanol extracts from dried algae and condensed ice from the lyophilisation process. The study revealed a high potential of allelochemicals of stoneworts for antibiotic treatments, which could be applied in several application fields. We found minor growth inhibition of eukaryotes, but strong effects on Cyanobacteria and A. fischeri with both life algae and extracts. HPLCanalyses of the extracts revealed neither intra-, nor interspecific differences of the composition, only quantitative differences were observed. Cyanobacteria were strongly affected by polar ice extracts indicating the presence of volatile allelochemicals. Application of allelopathically active extracts caused a strong decline of maximum fluorescence yield, a measure of physiological fitness, within the first few minutes and a partial recovery after 60 to 90 minutes. A comparison of active and non-active ice extracts based on GC-MS screening revealed complex patterns for active ones, however an identification of individual compounds was beyond the scope of this study.

“…At present the component (chemical) composition of essential oils extracted from several species of aquatic macrophytes growing on the territory of Russia has been identified, and constituent patterns related to biosynthesis of VOCs in freshwater ecosystems have been revealed [ 6 ]. Recently close attention has been paid to freshwater macrophytes as they can be a source of anticancer and antioxidative natural products [ 3 ].…”

The paper focuses on the assessment of the spectrum of biological activities (antineoplastic, anti-inflammatory, antifungal, and antibacterial) with PASS (Prediction of Activity Spectra for Substances) for the major components of three macrophytes widespread in the Holarctic species of freshwater, emergent macrophyte with floating leaves, Nuphar lutea (L.) Sm., and two species of submergent macrophyte groups, Ceratophyllum demersum L. and Potamogeton obtusifolius (Mert. et Koch), for the discovery of their ecological and pharmacological potential. The predicted probability of anti-inflammatory or antineoplastic activities above 0.8 was observed for twenty compounds. The same compounds were also characterized by high probability of antifungal and antibacterial activity. Six metabolites, namely, hexanal, pentadecanal, tetradecanoic acid, dibutyl phthalate, hexadecanoic acid, and manool, were a part of the major components of all three studied plants, indicating their high ecological significance and a certain universalism in their use by various species of water plants for the implementation of ecological and biochemical functions. This report underlines the role of identified compounds not only as important components in regulation of biochemical and metabolic pathways and processes in aquatic ecological systems, but also as potential pharmacological agents in the fight against different diseases.
