China journal of Chinese materia medica(2006)
Abstract
目的:研究民间草药箭叶橐吾根及根茎的化学成分.方法:乙醇总提物经反复硅胶柱色谱,Sephadex LH-20柱色谱纯化,根据理化性质和光谱数据鉴定化合物结构.结果:分离鉴定了7个萜类化合物,其中5个为倍半萜类,7α-hydroxy-9(10)-ene-1,8-dioxo-6,7-dihydrofuranoeremophilane(1),1β,10β-epoxy-6β,8β-dihydroxy-eremophil-7(11)-en-12,8α-olide(2),1-oxo-9-desoxycacalol(3),benzofuranoeremophil-1-ene(4),蜂斗菜内酯A(bakkenolide A)(5);2个为三萜类化合物,3β,16β-dihydroxy-12-oleanen-28-al(6)和羽扇醇(1upeol)(7).结论:化合物1~3和6为首次从箭叶橐吾中分离得到,其中化合物3和6为橐吾属内首次报道.
