在土耳其植物志中,豆科黄芪属植物大约有380种,分布于许多地区,在树胶生产中占据重要的经济地位。作者从疗伤黄芪(Astragalus vulneraria)地上部分中分离出1种新的黄酮醇苷(1)和1种已知黄酮醇二苷(2),根据光谱法确定了结构。 将干燥疗伤黄芪的地上部分(380g)粉碎,用80％乙醇回流提取,过滤,滤液真空浓缩至干,提取物反复经硅胶柱分
In the Flora of Turkey, there are about 380 species of Leguminosae, which are distributed in many areas and occupy an important economic position in the production of gum. The author isolated a novel flavonol glycoside (1) and a known flavonol diglycoside (2) from the aerial part of the wounded Astragalus vulneraria and determined the structure according to the spectroscopic method. The aerial part of the dry wound healing Astragalus membranaceus (380g) was crushed, extracted by refluxing with 80% ethanol, filtered, the filtrate was concentrated in vacuo to dryness, and the extract was repeatedly partitioned on a silica gel column.
