用各种柱色谱方法进行分离纯化,根据理化性质和波谱解析鉴定其化学结构,从而研究酸枣根中的化学成分。结果表明从酸枣分离得到7个化合物,分别鉴定为羽扇豆醇(Ⅰ),白桦酯酸(Ⅱ),美洲茶酸(Ⅲ),异美洲茶酸(Ⅳ),豆甾醇(Ⅴ),豆甾醇-3-O-葡萄糖苷(Ⅵ),蛇婆子碱(Ⅶ)。其中化合物Ⅳ、Ⅵ、Ⅶ为首次从该植物中得到。 A variety of column chromatography methods were isolated and purified, according to the physical and chemical properties and spectral analysis identified its chemical structure, in order to study the chemical composition of the jujube root. The results showed that seven compounds were isolated from Fructus Jujubae, which were identified as luteolin (Ⅰ), betulinic acid (Ⅱ), mellitic acid (Ⅲ), isomelic acid (Ⅳ), stigmasterol -3-O-glucoside (Ⅵ), snake povidone (Ⅶ). The compounds IV, VI and VII were obtained from this plant for the first time.
