The Business C,D,E,F,G,H,J,K,L und M, Ten New Tetranortriterpenes from Entandrophragma Bussei Harms Ten new tetranortriterpenes, busseins C, D, E, F, G., H, J, K, L and M have been isolated from the petroleum ether extract of the timber of Entandrophragma bussei Harms. utilizing separation by high‐pressure liquid chromatography (HPLC). The structural assignments are based mainly on spectral evidence. For the 1 H‐NMR spectroscopy extensive use of nuclear Overhauser effects (NOE) was made.
