From ethanolic extract of Viburnam cylindricum plant a new iridoid (1S,4aS, 6S, 7R, 7aS)- methyl 6-hydroxy-7-methyl-1-(3,4,5-trihydroxy-6-(hydroxymethyl) tetrahydro-2H-pyran-2yloxy)-1,4a,5,6,7,7a-hexahydrocyclopenta[c]pyran-4-carboxylate. have been isolated and characterized with help of 1H, 13C NMR, DEPT and 1H-1H COSY studies. These are new studies in chemical analysis of Viburnam cylindricum.

Viburnam cylindricum , (1S,4aS, 6S, 7R, 7aS)- methyl 6-hydroxy-7-methyl-1-(3,4,5-trihydroxy-6-(hydroxymethyl) tetrahydro-2H-pyran-2yloxy)-1,4a,5,6,7; 7a-hexahydrocyclopenta[c] pyran-4-carboxylate
