New Iridoid Glycosides and a Monoterpene Glycoside from Sumbucus ebulus L. (Caprifoliaceae)

From the roots of Sumbucus 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. 'H,'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.
