Three known natural compounds named n-heptacosan-1-ol (1), bis(2,3-dihydroxypropyl)-tetracosandioate (2) and moracin B (3) were firstly isolated from ethyl acetate extracts of the stem bark of Cassia grandis L.f. Their structures were elucidated by modern spectra including ESI-MS, 1D-NMR, 2D-NMR and by comparison with published data.
Keywords: Cassia grandis L.f, n-heptacosan-1-ol, bis(2, 3-dihydroxypropyl)-tetracosandioate, moracin B
