Abstract

Vicarin (1), a new isoflavone, has been isolated from the ethyl acetate-soluble fraction of the ethanolic extract of Eremostachys vicaryi, along with soforanarin B (2), luteolin 7-O-β-d-glucopyranoside (3), and hamighriprasin (4). Their structures were elucidated on the basis of their spectral data including MS and 2D NMR.
