    Notes: Aus dem ethanolischen Extrakt von Anchusa officinalis L. wurden drei neue Saponine, die Anchusoside 1, 2 und 7 isoliert. Die Verbindungen konnten durch IR-, 1H-NMR- und Massenspektroskopie sowie Hydrolysen als 3-O-β-D-Glucopyranosyloleanolsäure-α-D-glucopyranosylester (5), 3-O-[2,3-Di-O-(β-D-glucopyranosyl)-β-D-glucopyranosyl]oleanolsäure (7) und 3-[3-O-(β-D-Glucopyranosyl)-β-D-glucopyranosyl]oleanolsäure-α-D-glucopyranosylester (9) identifiziert werden (Daten in den Tabellen 1 und 2).
