A new 3-benzylchroman derivative from Sappan Lignum (Caesalpinia sappan)

Abstract

3′-Deoxy-4-O-methylepisappanol, a new 3-benzylchroman derivative, was isolated from Sappan Lignum, together with thirteen known chemical compounds identified as protosappanin A, sappanchalcone, sappanone B, palmitic acid, (+)-(8S,8′S)-bisdihydrosiringenin, brazilein, 3-deoxysappanchalcone, (+)-lyoniresinol, 3-deoxysappanone B, protosappanin B, isoprotosappanin B, 3′-O-methylbrazilin and brazilin, respectively. Among these known compounds, this is the first time that (+)-(8S,8′S)-bisdihydrosiringenin was obtained from the family Caesalpiniaceae. © 2008 by the authors; licensee Molecular Diversity Preservation International.
