Six new iridoid glycosides (1−6) of the “Valeriana type” were isolated from leaves of Sambucus ebulus. The structures were elucidated by 1D- and 2D-NMR spectroscopy, mass spectrometry, and chemical degradation methods as 10-O-acetylpatrinoside-aglycone-11-O-[4′′-O-acetyl-α-l-rhamnopyranosyl-(1→2)-β-d-ribohexo-3-ulopyranoside] (1), 7-O-acetylpatrinoside-aglycone-11-O-[4′′-O-acetyl-α-l-rhamnopyranos
