Abstract

The herb of Nonea rossica Steven (Boraginaceae) contained 23 compounds, including new acetates of astragalin and trifolin (1–5). UV and NMR spectroscopy and mass spectrometry found that the new flavonoids were kaempferol 3-O-(3′′-O-acetyl)-β-D-glucopyranoside (noneaside B, 1), kaempferol 3-O-(3′′-O-acetyl)-β-D-galactopyranoside (noneaside C, 2), kaempferol 3-O-(4′′-O-acetyl)-β-Dglucopyranoside (noneaside D, 3), kaempferol 3-O-(4′′-O-acetyl)-β-D-galactopyranoside (noneaside E, 4), and kaempferol 3-O-(3′′,6′′-di-O-acetyl)-β-D-galactopyranoside (noneaside F, 5).
