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.
