目的:研究大飞扬草地上部分的化学成分, 为研究其药理作用提供物质依据。方法:采用硅胶、大孔树脂、凝胶等柱层析方法, 从大飞扬草地上部分分离得到化合物, 并通过波谱方法确定其化学结构。结果:这些化合物分别是:东莨菪亭(1)、滨蒿内酯(2)、异东莨菪亭(3)、槲皮素(4)、异鼠李素(5)、乔松素(6)、山奈酚(7)、木犀草素(8)和没食子酸(9)。结论:这些化合物中, 1 3、5 8 为首次从该植物中分离得到。
OBJECTIVE: To study the chemical constituents in the part of wild grassland and provide the material basis for studying its pharmacological action. Methods: The compounds were isolated from large wild meadow grass by silica gel, macroporous resin and gel column chromatography. Their chemical structures were determined by spectroscopic methods. Results: The compounds were scopolamine (1), scopolamine (2), iso-scopolatin (3), quercetin (4), isorhamnetin (5) Kaempferol (7), luteolin (8) and gallic acid (9). Conclusion: Of these compounds, 1, 35, and 8 were isolated from this plant for the first time.
