Two new phenolic compounds, epicaesalpin J and 7,10,11-trihydroxydracaenone, were isolated from the heartwood of Caesalpinia sappan L. Their structures were identified by spectroscopic analysis methods, such as 1D and 2D NMR, along with the high resolution mass spectral data. The NO inhibition activities of two new compounds and six known compounds were tested.
