The seeds of Mimusops elengi yielded a newtriterpene, mimusic acid, whose structure was elucidated as 2β,3β,16α,23‐tetrahydroxyoleana‐5,13(18)‐dien‐28‐oic acid by NMR spectral studies. The detailed 1 H and 13 C NMR resonance assignments of this compound and of the previously reported congener mimusopic acid were achieved by using the 2D NMR techniques, HETCOR, COSY, NOESY and HMBC.
