从艾菊属 Tanacltum balsamita L.ssp.balsa-mitoides 植物中除分出已知成分(1)及(2)外,并得到一个新类型倍半萜成分,证明其结构为(3)式。取400克植物根粉,以乙醚-石油醚(1:2)提取,挝取物经硅胶柱层粗分,再用制备薄层(乙醚:石油醚=1:10)分离得到微量成分(1)及(2),并得到200毫克成分(3)。成分(3)命名为 balsamiton,为油状物。质谱分子量220,C_(15)H_(24)O,核磁显示三个甲基(δ0.96,双峰,J=6.5Hz;δ,0.94,双峰,J=6.5Hz;δ0.6单
A new type of sesquiterpenoid component was obtained from the plants of Tanacltum balsamita L.ssp.balsa-mitoides except that the known components (1) and (2) were separated, and the structure was proved to be (3). 400 g of plant root powder was taken and extracted with diethyl ether-petroleum ether (1: 2). The crude product was purified by silica gel column chromatography and then separated by preparative thin layer (ether: petroleum ether = 1: 10) ) And (2), and 200 mg of component (3) was obtained. Ingredient (3) is named balsamiton as an oil. MS (mass spectrum) 220, C 15 H 24 O, NMR showed three methyl groups (δ 0.96, doublet, J = 6.5Hz; δ, 0.94, doublet, J = 6.5Hz;
