摘要：

Two new anthraquinone derivatives sapranquinones A and B (1 and 2) together with two known biogenetically related anthraquinone derivatives (3 and 4) were isolated from the stems of Saprosma crassipes H. S. Lo. The structures of these compounds were elucidated using comprehensive spectroscopic methods. Compounds 1-4 were evaluated for their antibacterial activities and compounds 1 and 3 had a broad spectrum antibacterial activity against Staphylococcus albus, Escherichia coli, Bacillus cereus, Micrococcus tetragenus, and Micrococcus luteus with MIC values ranging from 1.25 to 5 mu g/mL.
