Isosweroside, a New Secoiridoid Glycoside from the Roots of Sambucus ebulus L. (Caprifoliaceae) The paper describes the isolation and structure elucidation of isosweroside (6‐(β‐D‐ glucopyranosyloxy)‐methyl‐9‐vinyl‐2,8‐dioxabicyclo[3.3.1]non‐6‐en‐3‐one), the first Valeriana‐type secoiridoid glycoside from the roots of Sambucus ebulus L. along with the two known glycosides ebuloside and morroniside.
