The leaves of Rhododendron seniavinii Maxim with little phytochemical information are used as folk remedies for the treatment of acute and chronic bronchitis in China. In our pursuing for the biologically active chemical constituents in the leaves, a new flavonoid glycoside 5,7,3′-trimethoxy-quercetin-3-O-β-d-glucopyranoside (1) was isolated from the water extract of its leaves, together with two known
很少有植物化学信息的杜鹃杜鹃叶被用作治疗中国急性和慢性支气管炎的民间药物。在我们的在叶追求为生物活性的化学成分,一个新的黄酮苷5,7,3'三甲氧基槲皮素-3- ö -β- d吡喃葡萄糖苷(1)从它的叶子的水提取物中分离,具有两个已知化合物5,7,3'三甲氧基槲皮素(一起2)和ovafolinin B-9'- ö -β- d吡喃葡萄糖苷(3)。通过光谱和化学方法阐明了新的类黄酮苷和两种已知化合物的结构。
