摘要
研究中药山楂根中的化学成分.利用硅胶柱、聚酰胺柱、葡聚糖LH-20柱色谱技术进行分离和纯化,根据理化性质以及UV,IR,ESI-MS,1H-NMR,13C-NMR等波谱数据分析鉴定结构.从山楂根中分离鉴定了4种化合物,分别为化合物(Ⅰ)5,7,4′-三羟基黄酮(芹菜素)、化合物(Ⅱ)2,3,4,6-四甲氧基-7-羟基二苯并呋喃、化合物(Ⅲ)β-胡萝卜苷、化合物(Ⅳ)β-谷甾醇.
Studies the proprietary constituents from the root were isolated by means of chromatography on silica gel, of crataegus. The chemical constituents polyamide and sephadex LH-20. Their structures were identified by spectral data and physicochemical characters. The compounds obtained were identified as 5, 7, 4＇-trihydroxyflavone （apigenin） （ Ⅰ）, 2, 3, 4, 6-tetramethoxy-7-hydroxydibenzofuran （ Ⅱ）, β-daucosterol （ Ⅲ）, and β -stigmastero 1（ Ⅳ ）.
