cytopiloyne, a polyacetylenic glucoside from bidens pilosa, acts as a novel anticandidal agent via regulation of macrophages.	bidens pilosa, a tropical and sub-tropical herbal plant, is used as an ethnomedicine for bacterial infection or immune modulation in asia, america and africa. it has been demonstrated that cytopiloyne (cp), a bioactive polyacetylenic glucoside purified from b. pilosa, increases the percentage of macrophages in the spleen but the specific effects on macrophages remain unclear.	2016	26924565
studies on bioactivity and secondary metabolites of crude extracts of bidens pilosa l. (asteraceae): a medicinal plant used in the transkei region of south africa.	whole plant-parts of bidens pilosa were powdered and extracted in concentrated hexane, acetone, ethanol, methanol and water. the extracts were tested for antimicrobial activity against escherichia coli (25922), bacillus subtilis (atcc 6051), enterococcus faecalis (51299) staphylococcus aureus (atcc 29213) and pseudomonas aeruginosa (atcc127853), using standard microbiological techniques. active crude extracts were macerated in concentrated methanol and tested for secondary metabolites including ...	2016	27166532
target and non-target site mechanisms developed by glyphosate-resistant hairy beggarticks (bidens pilosa l.) populations from mexico.	in 2014 hairy beggarticks (bidens pilosa l.) has been identified as being glyphosate-resistant in citrus orchards from mexico. the target and non-target site mechanisms involved in the response to glyphosate of two resistant populations (r1 and r2) and one susceptible (s) were studied. experiments of dose-response, shikimic acid accumulation, uptake-translocation, enzyme activity and 5-enolpyruvyl shikimate-3-phosphate synthase (epsps) gene sequencing were carried out in each population. the r1 ...	2016	27752259
data on the effect of cytopiloyne against listeria monocytogenes infection in mice.	cytopiloyne (cp), a novel polyacetylene compound extracted from b. pilosa, shows a multi-bioactivity, including immunomodulatory and antidiabetes. here, we investigated the anti-listeria effect of cytopiloyne in mice by assessing mortality, clearance of l. monocytogenes, and pathology examination. the data presented herein are supplemental to our research article entitled "cytopiloyne, a polyacetylenic glucoside from bidens pilosa, acts as a novel anticandidial agent via regulation of macrophage ...	2016	27761492
antioxidant 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 measured by electron paramagnetic resonance (epr) spectroscopy using stable 1,1-diphenyl-2-picrylhydrazyl ...	2016	18540165
