Beddomeilactone: a new triterpene from Dysoxylum beddomei.
An investigation of the leaves of Dysoxylum beddomei has yielded a novel triterpene, named beddomeilactone, together with six known triterpenoids: 3-oxotirucalla-7,24-dien-23-ol, dipterocarpol, niloticin, melianone, melianodiol and 24-epi-melianodiol. The structure and stereochemistry of the new compound were determined on the basis of mass, 1D and 2D NMR spectroscopies including NOE difference and spin-spin decoupling studies.
