摘  要: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),benzofumnoeremophil-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(lupeol)(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。Objective: To study the chemical constituents of radix and rhizome of Ligularia sagitta. Method: Isolation and purification were carried out on the column chromatography of silica gel and sephadex LH - 20. The structures were identified by spectral analysis. Result: Seven terpenoid compounds were isolated from the radix and rhizome of L. sagitta. Five of them are sesquiterpenoids, the structures were determined as 7α-hydroxy-9( 10)-ene-1,8-dioxo-6, 7-dihydrofuranoeremophilane (1), 1β, 10β-epoxy-6β, 8β-dihydroxy-eremophil7 ( 11 ) -en-12, 8α-olide ( 2 ), 1-oxo-9-desoxycacalol ( 3 ), benzofuranoeremophil-l-ene ( 4 ) and bakkenolide ($) ; other two compounds belong to triterpenoid. 3β, 16β-dihydroxy-12-oleanen-28-al (6) and lupeol (7). Conchmlon: Corn- poundsl-3 and 6 were: isolated from L. sagitta for the first time, and compounds 3 and 6 were obtained from Ligularia for the first time,
