From the 95% EtOH extract of dried aerial parts of Clematis tashiroi, eight new and four known phenolic (caffeic acid, coumaric acid, ferrulic acid) glycosides were isolated and characterized. The structures of the new isolates (clematisides A-H) were elucidated by spectroscopic data interpretation
In this study, response surface methodology (RSM), based on Box-Behnken design, was employed to optimize the extraction conditions of polysaccharide from Clematis huchouensis Tamura (CP). And then the antioxidant activities of the samples were investigated including scavenging effects of superoxide
The antioxidant activities of crude extract fractions using Hexane, Chloroform, Ethyl Acetate, Butanol and Water of Clematis orientalis and Clematis ispahanica were investigated. 1,1-diphenyl-2-picryl-hydrazyl (DPPH) assay and the ferric reducing/antioxidant potential (FRAP) were used to evaluate
Clematis florida Thun (CfT) is an ornamental and medicinal plant. It is a cold resistant but heat sensitive species and deserves to be further investigated to improve its adaptability to heat stress. Exploring the molecular mechanism potential via an omic-analysis constitutes a promising approach
Clematis gouriana (Ranunculaceae), a perennial herb, is used by the local inhabitants of the western Himalayan region for its medicinal properties. Major bioconstituents of C. gouriana leaves using different solvent extracts were obtained and analysed. The results revealed promising contents of
Clematis crassifolia and Clematis cadmia Buch.-Ham. ex Hook.f. & Thomson are herbaceous vine plants native to China. C. crassifolia is distributed in shaded areas, while C. cadmia mostly grows in bright, sunny conditions in mountainous and hilly landscapes. To understand the potential mechanisms
Clematis orientalis Linn has long been used as ethnopharmacy for the treatment of arthritis. This study is intended to evaluate the curative efficacy of Clematis orientalis in treating polyarthritis in rats. Aqueous ethanolic extract and fractions (hexane, butanol and aqueous) were administered
Clematichinenoside is a triterpenoid saponin isolated from the roots of Clematis chinensis. Oxidative stress and excessive nitric oxide production are thought to play considerable roles in ischemia/reperfusion injury that impairs cardiac function. The present study investigated the protective effect
BACKGROUND
Discovery of new plant species with antioxidant properties is a priority of many research teams. Most of the species included in this study are unstudied for antioxidant properties, but they are taxonomically related to reference plants with well-documented antioxidant
A new flavone C-glycoside, isovitexin 6''-O-E-p-coumarate (1) and two known flavonoid glycosides--quercetin 3-O-beta-D-glucuronopyranoside (2) and isoorientin (3)--were isolated from an ethanol extract of aerial parts of Clematis rehderiana. Their structures were determined by spectroscopic methods.
Mitochondria-mediated cardiomyocyte apoptosis is involved in myocardial ischemia/reperfusion (MI/R) injury. Clematichinenoside (AR) is a triterpenoid saponin isolated from the roots of Clematis chinensis with antioxidant and anti-inflammatory cardioprotection effects against MI/R injury, yet the
Background. Benzo[a]pyrene (B[a]P), a polycyclic aromatic hydrocarbon present in the atmosphere, has cytotoxic and carcinogenic effects. There have been no reports to demonstrate involvement of Clematis apiifolia DC. extract (CAE) in B[a]P-induced effects. This study was conducted to
Proinflammatory cytokine TNF-α-induced adhesion of leukocytes to endothelial cells plays a critical role in the early stage of atherosclerosis. Oxidative stress and redox-sensitive transcription factors are implicated in the process. Thus, compounds that mediate intracellular redox status and
The aerial part of Clematis flammula (Ranunculaceae) has been traditionally used in the treatment of skin diseases including mycotic infection in the Tunisian traditional medicine. The study was undertaken to extract and determine the essential oil chemical composition of Clematis flammula aerial
Microglia are main immune cells to exacerbate neural disorders in persistent overactivating. Therefore, it is a good strategy to regulate microglia for the treatment of neural disorders. In the present study, we isolated and characterized a novel compound, 5-O-isoferuloyl-2-deoxy-D-ribono-γ-lacton
