New Iridoid Glycosides and a Monoterpene Glycoside from Sambucus ebulus L. (Caprifloiaceae) From the roots of Sambucus ebulus L., two novel valeriana‐type ester iridoid glycosides, 6′‐ O ‐apiosylebuloside ( 1 ) and 7,7‐ O ‐dihydroebuloside ( 3 ), along with the open‐chain monoterpene glycoside 5 were isolated. Their structure elucidation is based mainly on one‐ and two‐dimensional NMR methods. 1 H, 1 H‐COSY experiments permitted complete assignment of signals arising from the disaccharide unit in 1 . Biogenetically, 3 seems to represent the equivalent of loganin in the valeriana‐type series of iridoid glycosides.
