title: New flavanone and chalcone glucosides from Bidens bipinnata Linn.
abstract: A new flavanone glucoside, bidenoside F, and a new chalcone glucoside, bidenoside G, along with the known compound iso-okanin 7-O-(4'',6''-diacetyl)-beta-D-glucopyranoside have been isolated from the aerial parts of Bidens bipinnata L. The structures were determined on the basis of spectroscopic methods.
