From ethanolic extract of Viburnam cylindricum plant a (4aS, 5R, 6S)-6-(3,4,5-trihydroxy-6(hydroxymethyl) tetrahydro-2H-pyran-2-yloxy)-5-vinyl-4,4a,5,6-tetrahydropyrano[3,4-c]pyran-1(3H)-one Iridoid  have been isolated and characterized with help of 1H, 13C NMR, 1H-1H COSY, DEPT and HMQC  studies. This is new studies in chemical analysis of Viburnam cylindricum.  

Viburnam cylindricum; Capriofoliaceae; (4aS,5R,6S)-6-(3,4,5-trihydroxy-6(hydroxymethyl)tetrahydro-2H-pyran-2-yloxy)-5-vinyl-4,4a,5,6-tetrahydropyrano [3,4-c]pyran-1(3H)-one
