| Abstract: | The structure of yuehchukene, a new bis-indole alkaloid isolated from the root of Murraya paniculata (L.) Jack, has been determined by an X-ray crystallographic analysis of its mono-N-acetylated derivative. C28H28N2O,FW = 408.54, monoclinic, space group P21/n, a/3 = 8.032(2), b = 19.712(8), c =14.460(7) A, β = 101.22(2)°, U = 2245.7(9) A, Dm (flotation in KI/H2O) =1.20 g cm-3 , Z = 4, Dc = 1.208 g cm-3, F(OOO) = 871.86, μ(Mo-Ka) =0.68 cm-1 ,final R =0.079 and Rg = 0.084 for 1523 observed data. |
