摘　　要：为了解降龙草(Hemiboea subcapitata Clarke)的化学成分,从降龙草全草的乙醇提取物的石油醚和乙酸乙酯萃取部位分离得到了5个蒽醌类化合物。经波谱学分析鉴定为digiferruginol(1)、1,4-二羟基-2-羟甲基-9,10-蒽醌(2)、1,7-二羟基-2-羟甲基-9,10-蒽醌(3)、1-羟基-7-甲氧基-2-羟甲基-9,10-蒽醌(4)和1,4,7-三羟基-2-甲基-9,10-蒽醌(5)。其中化合物4和5为新化合物,其它3个化合物为首次从降龙草中分离得到。In order to understand the chemical constituents of Hemiboea subcapitata Clarke, ifve anthraquinones from ethanol extract of H. subcapitata. On the basis of spectral data, their structures were identified as digiferruginol (1), 1,4-dihydroxy-2-hydroxymethyl-9,10-anthraxqui-none (2), 1,7-dihydroxy-2-hydroxymethyl-9,10-anthraquinone (3), 1-hydroxy-7-methoxy-2-hydro-xymethyl-9,10-anthraquinone (4), and 1,4,7-trihydroxy-2-methyl-9,10-anthraquinone (5). Among them, compounds 4 and 5 are reported for the ifrst time , and other three anthraquinones were also obtained from this plant for the ifrst time.
