The structures of these compounds were determined by comprehensive spectroscopic analyses of 1D and 2D NMR and EI- and ESI-MS and comparison with the reported data. Above compounds are reported here from this species for the first time. In addition, acetylation of citracridone I (2) and citruisinine II (3) provided the hitherto not reported monoacetyl derivatives 2a and 3a, respectively. Crude extracts
