The ability to succeed in diverse conditions is a key factor allowing introduced species to successfully invade and spread across new areas. Two non-exclusive factors have been suggested to promote this ability: adaptive phenotypic plasticity of individuals, and the evolution of locally adapted populations in the new range. We investigated these individual and population-level factors in Polygo...
To determine the potential utility of Polygonum hydropiper (tade) as an anti-dementia functional food, the present study assessed the acetylcholinesterase inhibitory and anti-inflammatory activities of tade crude extracts in human cells. Crude extracts of tade were obtained by homogenizing tade in distilled water and then heating the resulting crude extracts. The hot aqueous extracts were purif...
Resveratrol, a polyphenol compound with strong biological activity, has been widely used in medicine, health products and cosmetic industries. It is also the main active component of Polygonum cuspidatum, a well-known traditional Chinese medicine. We developed a simple and effective method for the preparation of resveratrol from P. cuspidatum. The whole preparative process consisted of reflux e...
PREMISE OF STUDY The presence of genetic variation for traits that contribute to ecological range expansion can provide the potential for introduced taxa to evolve greater invasiveness. Genotypes that contribute to the spread of introduced range populations must have the ability to maintain fitness under changing environmental stress and competitive intensity. Previously, we identified a subset...
گونه polygonum glabrum که از شمال شرق و برخی از مناطق دیگر ایران جمع آوری شده، برای اولین بار از ایران گزارش می شود. این گونه در رویشگاههای مرطوب و حاشیه مزارع دیده شده است.

background: herbal medicine is a new complementary strategy for treating diseases such as cancer. however, its mechanism of action is not clear yet. this study investigates antitumor efficacy of polygonum avicular extract on mcf-7 cell line . methods: mcf-7 cells were treated with different concentrations of (50, 100, 150, 200, 250, 300,350 400 ng/âµl) polygonum avicular at different time inter...
Potato (Solanum tuberosum L.) is cultivated in India in a commercial scale and this crop is susceptible to various insect pests of which aphids (both Myzus persicae Sulzer and Aphis gossypii Glover) cause heavy damage especially by spreading virus diseases. Studies were made to evaluate efficacy of extracts from plants such as Pongamia pinnata L. and Nicotiana tabacum L. and Polygonum hydropipe...
