title: A new bicoumarin from the leaves and stems of Triphasia trifolia.
abstract: A new bicoumarin (3) was isolated from the leaves and stems of Triphasia trifolia. Its structure was determined by spectral data, in particular two-dimensional NMR experiments. It appeared that the two coumarinic moieties of 3 are derivatives of mexoticin (1) and meranzin hydrate (2), which are known constituents of the plant.
