Willow herb tea or preparation are available and relatively popular in the European market, and claimed to be effective inter alia because of their anti-inflammatory activity. The present study is therefore aimed at comparing the anti-inflammatory and antioxidant activity of extracts of the three most popular Epilobium species (E. angustifolium, E. hirsutum(More)
In this study, we synthesized several imperatorin analogs using imperatorin and xanthotoxin as substrates. The anti-cholinesterase activities of all compounds were evaluated in in vitro experiments according to the modified Ellman's method. For each synthesized compound, IC50 values for both enzymes were established. Galantamine hydrobromide was used as a(More)
Extracts from Epilobium sp. herbs have been traditionally used in the treatment of prostate-associated ailments. Our studies demonstrated that the extracts from Epilobium angustifolium, Epilobium parviflorum and Epilobium hirsutum herbs are potent prostate cancer cells (LNCaP) proliferation inhibitors with IC50 values around 35 µg/ml. The tested extracts(More)
SCOPE Ellagitannin-rich food products and medicinal plant materials were shown to have beneficial effects toward intestinal inflammation. Due to the questionable bioavailability of ellagitannins their gut microbiota metabolites-urolithins have come to be regarded as potential factors responsible for biological activities observed in vivo. The aim of the(More)
ETHNOPHARMACOLOGICAL RELEVANCE Ellagitannin-rich plant materials are widely used in traditional medicine as effective, internally used anti-inflammatory agents. Due to the not well-established bioavailability of ellagitannins, the mechanisms of observed therapeutic effects following oral administration still remain unclear. The aim of the study was to(More)
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(More)
Ellagitannin-rich products exhibit beneficial influence in the case of inflammation-associated diseases. Urolithins, metabolites of ellagitannins produced by gut microbiota, in contrary to high molecular weight hydrophilic parental polyphenols, possess well established bioavailability. Because of the important role of neutrophils in progression of(More)
A reversed phase high performance liquid chromatography method (HPLC) coupled with a diode array, charged aerosol detector or mass spectrometer was developed for the quantitative and qualitative standardization of Agrimoniae eupatoriae herba (Ph. Eur). Twenty four constituents comprising phenolic acids, flavan-3-ol derivatives, ellagitannin and flavonoids(More)
Scorzonera hispanica commonly known as black salsify is a perennial herbaceous plant belonging to the Asteraceae family. The subaerial parts of black salsify are cultivated in Central and Southern Europe as a vegetable. There are only few reports on the chemical composition of S.hispanica. The aim of the present study was to determine the chemical(More)
Isolation and identification of the inhibitors of butyrylcholinesterase (BChE), obtained from the extracts of roots and fruits of Angelica archangelica L., are reported. Our results confirmed the weak inhibitory effect of Angelica roots on acetylcholinesterase activity. BChE inhibition was much more pronounced at a concentration of 100 μg/mL for hexane(More)
