射干的化学成分研究(Ⅱ)

Study on chemical constituents of Belamcanda chinensis (Ⅱ)

目的 研究中药射干的化学成分。方法 采用硅胶柱色谱及 Sephadex L H- 2 0等色谱技术分离纯化 ,根据理化性质及色谱数据鉴定结构。结果 从射干乙醇提取物的醋酸乙酯萃取部分分得 3个化合物 ,分别为异鼠李素(isorham netin, )、粗毛豚草素 (hispidulin, )、白射干素 (dichotom itin, ) ,从乙醇提取液正丁醇萃取部分分离得到 4个化合物 ,分别为 :鸢尾苷 (iridin, )、野鸢尾苷 (tectoridin, )、胡萝卜苷 (daucosterol, )、维太菊苷(vittadinoside or stigm asterol- 3- O- glucoside, )。结论 其中化合物 为首次从该植物中分得。

ObjectTo investigate the chemical constituents in the rhizoma of Belamcanda chinensis (L.) DC. MethodsThe chemical constituents were isolated and purified by solvent extraction together with various chromatographic techniques. The structures were elucidated on the basis of chemical evidence and spectral data. ResultsThree compounds were isolated from the EtoAC extracts of the rhizome of B. chinensis which were isorhamnetin (Ⅹ), hispidulin (Ⅺ), dichotomitin ( ⅩⅡ); four compounds were isolated from n-BuOH extracts, which were iridin ( ⅩⅢ), tectoridin (ⅩⅣ), daucosterol ( ⅩⅤ), vittadinoside or stigmasterol-3-O-glucoside ( ⅩⅥ). ConclusionCompound Ⅺ is isolated from this medicinal plant for the first time.
