Quercetin 3-O-beta-(2(")-galloyl)-rhamnopyranoside (QGR) is a naturally occurring quercitrin gallate, which is a polyphenolic compound that was originally isolated from Persicaria lapathifolia (Polygonaceae). QGR has been shown to have an inhibitory effect on nitric oxide (NO) production in lipopolysaccharide (LPS)-stimulated macrophage RAW 264.7 cells. Therefore, this study was conducted to in...

Interspecific hybridization followed by polyploidization appears to have played a major role in plant diversification, but quantifying the contribution of this mechanism to diversification within taxonomically complex clades remains difficult. Incongruence among gene trees can provide critical insights, especially when combined with data on chromosome numbers, morphology, and geography. To furt...

Persicaria amphibia (subfam. Polygonoideae), an aquatic macrophyte rich in dietary polyphenolics, is used as a traditional remedy and culinary herb. Nevertheless, P. from the Balkan region has been insufficiently studied underutilized. Here, cytotoxicity antimicrobial properties of previously chemically characterised ethanol extract aerial parts were tested. The following methods carried out: M...

Pelargonic acid is the most successful natural herbicide and can contribute to reducing synthetic herbicides, but information on its efficacy contrasting. Given high cost, a reduction of rate could facilitate spread use this herbicide. Two greenhouse three field experiments were conducted evaluate herbicidal different doses pelargonic several weeds (Abutilon theophrasti, Alopecurus myosuroides,...
