Structure of the new monoterpenoid liganolide

The structure of the new ester liganolide C₂₇H₃₈O₈, isolated from the roots ofLigularia thomsonii has been established by x-ray structural analysis. Liganolide is a monoterpenoid including a six-membered ring with substitutents at C(2), C(3), and C(4), and an epoxy group at C(1) and C(6).
