Methods column, Sephadex LH-20, ODS RP-column chromatography, and other means of separation and, through ESI / MS, NMR spectroscopy, and other identified compounds. The results obtained by seven single compound, through the ESI / MS, NMR spectroscopy, and other methods identified which of the two compounds, respectively 4 - methoxy-table hematoxylin alcohol (4 - methoxyepisappanol) and HE Charles ketone ( sappanchalcone). Research findings show that HE (Caesalpinia sappan L.) for the leguminous plants-is to phenolic material-based extract of the monomer and a large number of pharmacological activity and research value, this study identified and identification of the hematoxylin Two compounds. |
