AbstractFour new pterocarpinoids, sphenostylin A, B, C, and D (1–4), have been isolated from the CHCl3extract of the root bark ofDolichos marginatassp.erecta(Leguminosae) by preparative liquid chromatography. The structures have been established by spectroscopic methods (UV,1H‐NMR,13C‐NMR, EI‐MS, DCI‐MS, CD) and chemical transformations. The isolated compounds showed weak antifungal activity againstCladosporium cu
