Abstract

Three aromatic compounds named brazilin (1), protosappanin C dimethyl acetal (2) and protosappanin B (3) were isolated from the dried heart-wood of Caesalpinia sappan L. (Caesalpinia family). Their chemical struture of these constituents were deduced by their spectral data and comparision with published data.
