Antibacterial Activities and Antibacterial Mechanism of Polygonum cuspidatum Extracts against Nosocomial Drug-Resistant Pathogens.
Recently, drug resistance due to the extensive abuse and over-use of antibiotics has become an increasingly serious problem, making the development of alternative antibiotics a very urgent issue. In this study, the Chinese herbal medicine, Polygonum cuspidatum, was extracted with 95% ethanol and the crude extracts were further purified by partition based on solvent polarity. The antimicrobial a...
متن کاملConstituents from Polygonum cuspidatum.
Two lignan sulfates, a stilbene derivative and a phenol sulfate, together with 10 known compounds, were isolated from an aqueous extract of the root of Polygonum cuspidatum. The new compounds were elucidated based on chemical evidence and spectroscopic techniques including two-dimensional NMR methods. They exhibited no inhibition of lipid peroxidation and no cytotoxic and DNA cleavage activities.
متن کاملEffects of Polygonum Cuspidatum Containing Resveratrol on Inflammation in Male Professional Basketball Players
BACKGROUND Exercise can lead to acute oxidative stress, which can result in oxidative damage and induce inflammation. Resveratrol may reduce the levels of inflammatory cytokines. Thus, we investigated the effects of this compound on the plasma levels of tumor necrosis factor-α (TNF-α) and interleukin 6 (IL-6) in male professional basketball players. METHODS Twenty healthy male professional ba...
متن کاملHigh-performance liquid chromatographic separation is performed to extract active components from the traditional Chinese medicine Polygonum cuspidatum using a trans-resveratrol imprinted polymer. Good separation and purification of trans-resveratrol and emodin from the Polygonum cuspidatum
to extract active components from the traditional Chinese medicine Polygonum cuspidatum using a trans-resveratrol imprinted polymer. Good separation and purification of trans-resveratrol and emodin from the Polygonum cuspidatum extract are achieved after condition optimization. The extraction recoveries are 83% and 99% for trans-resveratol and emodin, respectively. The results show that the mol...
متن کاملAn antiinflammatory and reactive oxygen species suppressive effects of an extract of Polygonum cuspidatum containing resveratrol.
BACKGROUND Resveratrol have been shown to exert an antiinflammatory and antiaging effects in vitro and in animal models. OBJECTIVE The objective of the study was to investigate the effect of a Polygonum cuspidatum extract (PCE) containing resveratrol on oxidative and inflammatory stress in normal subjects. RESEARCH DESIGN AND METHODS Two groups (10 each) of normal-weight healthy subjects we...
