title: New acetylenic glucosides from Bidens bipinnata LINNE.
abstract: Two new acetylenic glucosides, 8Z-decaene-4,6-diyn-1-O-beta-D-glucopyranoside named bidenoside C, and 8E-decaene-4,6-diyn-3,10-dihydroxy-1-O-beta-D-glucopyranoside named bidenoside D, have been isolated from the aerial parts of Bidens bipinnata LINNE (Asterceae). These structures have been elucidated on the basis of spectroscopic methods.
