-epineoruscogenin (4) together with two known compounds, bletilnoside A (5) and 3-O-β-d-glucopyranosyl-3-epi-neoruscogenin (6), were isolated from the ethanol extract of the roots of Bletilla striata (Thunb.) Reichb. f. The structures of the isolated compounds were established based on 1D and 2D ((1)H-(1)H COSY, HMQC, and HMBC) NMR spectroscopy, in addition to high resolution mass spectrometry. The
