Immunomodulatory activity of acidic polysaccharides isolated from Tanacetum vulgare L.
Tanacetum vulgare L. (Tansy) has been extensively used in folk medicine for treatment of a variety of medical disorders. In the present study, we isolated and purified four acidic polysaccharide fractions (designated T-I to T-IV) from Tansy florets by the sequential use of hot-water extraction, ethanol precipitation, ultra-filtration, anion-exchange, and size-exclusion chromatography. The avera...
متن کاملCharacterization and Antimicrobial Activity of Volatile Constituents from Fresh Fruits of Alchornea cordifolia and Canthium subcordatum
Bacterial resistance has been increasingly reported worldwide and is one of the major causes of failure in the treatment of infectious diseases. Natural-based products, including plant secondary metabolites (phytochemicals), can be exploited to ameliorate the problem of microbial resistance. The fruit essential oils of Alchornea cordifolia and Canthium subcordatum were obtained by hydrodistilla...
متن کاملImmunomodulatory activity of polysaccharides isolated from Clerodendrum splendens: Beneficial effects in experimental autoimmune encephalomyelitis
BACKGROUND Extracts of leaves from Clerodendrum have been used for centuries to treat a variety of medicinal problems in tropical Africa. However, little is known about the high-molecular weight active components conferring therapeutic properties to these extracts. METHODS Polysaccharides from the leaves of Clerodendrum splendens were extracted and fractionated by ion exchange and size-exclus...
متن کاملImmunomodulatory activity and partial characterisation of polysaccharides from Momordica charantia.
Momordica charantia Linn. is used as an edible and medicinal vegetable in sub-tropical areas. Until now, studies on its composition and related activities have been confined to compounds of low molecular mass, and no data have been reported concerning the plant's polysaccharides. In this work, a crude polysaccharide of M. charantia (MCP) fruit was isolated by hot water extraction and then purif...
متن کاملAntioxidant properties and Glutathione S-transferases inhibitory activity of Alchornea cordifolia leaf extract in Acetaminophen toxicity
Paracetamol (acetaminophen, PCM) is a widely used over-the-counter analgesic and antipyretic drug. Intake of a large dose of PCM may result in severe hepatic necrosis. Oxidative stress is mediated by oxidative capacities of the PCM metabolite (N-acetyl-para-benzo quinoneimine, NAPQI), which covalently binds to proteins and other macromolecules to cause cellular damage. At low doses, NAPQI is ...
