Triterpenoids from Viburnum suspensum.
Three triterpenoids, 3-oxo-11,13(18)-oleanadien-28-oic acid, 24-hydroxy-3-oxo-11,13(18)-oleanadien-28-oic acid, 6 beta-hydroxy-3-oxo-11,13(18)-oleanadien-28-oic acid have been isolated together with the previously known virgatic acid, vibsanin B and 3-hydroxyvibsanin E from the leaves of Viburnum suspensum. Their structures were determined by spectroscopic methods and by comparison of their NMR spectral data with those of the previously known 11,13(18)-oleanadien-3 beta-ol.
