英文摘要	Five new quinone derivatives, (R)-7-hydroxy-α-dunnione (1), (R)-8-hydroxy-α-dunnione (2), (R)-7,8-dihydroxy-α-dunnione (3), (R)-7-methoxy-6,8-dihydroxy-a-dunnione (4), and 1,7-dihydroxy-2-hydroxymethylanthraquinone (5), along with seven known compounds, were isolated from Chirita eburnea. All structures were elucidated by spectroscopic techniques (NMR, MS, UV, and IR). The EtOAc fraction of the EtOH extract and compounds 3 and 4 showed free radical (DPPH) scavenging activity, with IC50 values of 101.7 &PLUSMN; 5.2 μ g/mL, 124.82 &PLUSMN; 8.4 μ M, and 45.72 &PLUSMN; 3.6 μ M, respectively, compared with 86.91 &PLUSMN; 6.8 μ M for ascorbate.
