title: Loasins A and B, new flavonoids from Eremostachys loasifolia.
abstract: Loasins A (1) and B (2), new flavonoids, have been isolated from the ethyl acetate soluble sub-fraction of the ethanolic extract of Eremostachys loasifolia along with apuleisin (3) and apuleidin (4), isolated for the first time from this species. Their structures were assigned on the basis of their spectral data including 1D and 2D NMR.
