Protection from oxidative damage using Bidens pilosa extracts in normal human erythrocytes.
Bidens pilosa (B. pilosa) is well known in Taiwan as a traditional Chinese medicine. The purpose of this study was to evaluate the ability of both the ethanol (EtOH) and ethylacetate/ethanol (EA/EtOH) extracts from the whole B. pilosa plant, to protect normal human erythrocytes against oxidative damage in vitro. It was determined that the oxidative hemolysis and lipid/protein peroxidation of er...
متن کاملFlavonoids, centaurein and centaureidin, from Bidens pilosa, stimulate IFN- expression
Bidens pilosa is used as an ethnical medicine for bacterial infection or immune modulation in Asia, America and Africa. Here, we employed n IFNpromoter-driven luciferase reporter construct and T cells to characterize immunomodulatory compounds from this plant based on a ioactivity-guided isolation principle. We found that PHA, a positive control, caused a six-fold increase in IFNpromoter activi...
متن کاملAntioxidant activity of extracts and flavonoids from Bidens tripartita.
Extracts from herb and flowers of Bidens tripartita L. (Asteraceae), obtained using solvents of different polarity, were studied for their radical scavenging effects. Antioxidant activities of pure flavonoids: flavanomarein (isookanin 7-O-glucoside), cynaroside (luteolin 7-O-glucoside) and luteolin, which had been isolated from this plant, were also evaluated. Radical-scavenging activity was me...
متن کاملCompilation of secondary metabolites from Bidens pilosa L.
Bidens pilosa L. is a cosmopolitan annual herb, known for its traditional use in treating various diseases and thus much studied for the biological activity of its extracts, fractions and isolated compounds. Polyacetylenes and flavonoids, typical metabolite classes in the Bidens genus, predominate in the phytochemistry of B. pilosa. These classes of compounds have great taxonomic significance. ...
متن کاملAnti-adult T-cell leukemia effects of Bidens pilosa.
We evaluated the effects of Bidens pilosa, a plant found in tropical and subtropical regions, and investigated the molecular pathways responsible for the anti-adult T-cell leukemia (ATL) effect. Water extracts of B. pilosa had growth suppressive effects on human T-cell leukemia virus type 1 (HTLV-1)-infected T-cell lines and ATL cells. B. pilosa extracts arrested cells in G1 cell cycle and indu...
