Abstract
A new norisoprenoid, (3 R,6 R,7 E)-3-hydroxy-4,7-megastigmadien-9-one, was isolated together with seven known norisoprenoids, (−)-loliolide, (+)-isololiolide, (6 R,7 E)-4,7-megastigmadien-3,9-dione, (6 S,7 E)-6-hydroxy-4,7-megastigmadien-3,9-dione, (3 S,7 E)-3-hydroxy-5,7-megastigmadien-9-one, (3 S,5 R,6 S,7 E)-5,6-epoxy-3-hydroxy-7-megastigmene-9-one, (3 S,5 R,7 E,8 R)-3,5-dihydroxy-6,7-megastigmadien-9-one and eight known phenolic compounds, trans-ferulic acid, cis-ferulic acid, trans- p-coumaroyl methyl ester, umbelliferone, veratric acid, p-hydroxybenzaldehyde, p-hydroxybenzoic acid, p-methoxybenzoic acid, from the leaves of Viburnum dilatatum. Their structures were established on the basis of chemical evidence and spectral data.
