New flavanone and chalcone glucosides from Bidens bipinnata Linn.

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)-β-d-glucopyranoside have been isolated from the aerial parts of Bidens bipinnata L. The structures were determined on the basis of spectroscopic methods.
