Two new antioxidant compounds, securixanthones C (1) and D (2) were isolated from the stems of Securidaca inappendiculata Hassk. The structures of the two new compounds were established on the basis of EI-MS, 1D-NMR and 2D-NMR, UV, and IR experiments. Key words: Securidaca inappendiculata; Polygalaceae; securixanthone C; securixanthone D
