目的 研究黄背栎(Qnercus pannosa Hand.-Mazz.)中的黄酮类化学成分.方法 利用Sephadex LH-20及硅胶等柱色谱技术进行化合物的分离和纯化,根据理化性质、光谱数据对其结构进行鉴定.结果 得到5个黄酮类化合物,分别鉴定为(+)-catechin(1),(-)-epicatechin(2),(2R,3R)-(-)-二氢槲皮素3-O-β-D-葡萄糖苷(3),(2R,3R)-(-)-二氢槲皮素3-O-β-D-木糖苷(4),chamaechromone(5).结论 这5个化合物均为首次从黄背栎中分离得到. |

OBJECTIVE To investigate the chemical constituents of Quercus pannosa Hand.-Mazz..METHODS The com- pounds were isolated and purified via silica gel and Sephadex LH-20 column chromatography repeatedly and their structures were elu- cidated on the basis of spectroscopic evidences and physiochemical properties.RESULTS Five flavanoids were isolated and identified as(+)-catechin(1),(-)-epicatechin(2),(2R,3R)-(-)-dihydroquercetin 3-O-β-D-glucopyranoside(3),(2R,3R)-(-)-di- hydroquercetin 3-O-β-D-xylopyranoside(4),chamaechromone(5)respectively.CONCLUSION All compounds are isolated from the plant for the first time. |
