Antihyperglycemic Acetylenic Glucosides fromBidens pilosa

Planta Medica, 2009
In vivo bioassay-guided fractionation of the aqueous alcohol extract of the aerial parts of Bidens pilosa Sch. Bip. var. radiata (Asteraceae) using C57 BL/Ks-db/db mice as a model for type 2 diabetes, yielded two known polyacetylenic glucosides, identified as 2-beta-D-glucopyranosyloxy-1-hydroxy-5(E)-tridecene-7,9,11-+ ++triyne (1) and 3-beta-D ...

Pathogenic mycobiota of the weeds Bidens pilosa and Bidens subalternans

Tropical Plant Pathology, 2015
Bidens pilosa and B. subalternans are highly noxious herbaceous neotropical asteraceous weeds. A survey of fungal pathogens associated with these two species was undertaken in Brazil, aimed at finding natural enemies in order to establish the potential for introducing novel specific pathogens from other regions of the world, as classical biological ...
