Two new isoflavone glycosides from Mucuna birdwoodiana

J Asian Nat Prod Res. 2010 Mar;12(3):199-203. doi: 10.1080/10286020903517540.

Abstract

Two new isoflavone glycosides, mucodianins E (1) and F (2), have been isolated from the vine stems of Mucuna birdwoodiana Tutch. Their structures have been established as retusin 7-O-beta-D-xylopyranosyl-(1 --> 6)-beta-D-glucopyranoside (1) and 8-O-methylretusin 7-O-beta-D-xylopyranosyl-(1 --> 6)-beta-D-glucopyranoside (2) by means of spectroscopic analysis and chemical methods.
