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 ...
