Abstract

Two new iridoids, methyl (+)‐rel‐(1__R__,3__S__,4__R__,5__R__,8__R__,9__R__)‐1,3,4,5,8,9‐hexahydro‐8‐hydroxy‐3‐methoxy‐2__H__‐1a,2‐dioxacyclopent[cd]indene‐4‐carboxylate (1) and methyl (+)‐rel‐(1__R__,3__S__,4__S__,5__R__,8__R__,9__R__)‐1,3,4,5,8,9‐hexahydro‐8‐hydroxy‐3‐methoxy‐2__H__‐1a,2‐dioxacyclopent[cd]indene‐4‐carboxylate (2), were isolated from Viburnum cylindricum along with 14 known compounds. Their structures were determined by spectroscopic analyses. This type of iridoids bearing a MeO group at C(3) was discovered for the first time.
