目的研究大叶橐吾的化学成分。方法应用多种色谱方法和色谱材料进行提取、分离和纯化,用各种现代光谱方法解析结构。结果从大叶橐吾根茎的乙醇提取物中分离纯化到四个黄酮醇苷和两个单萜苷,分别为甲基鼠李素3OβD芸香糖苷(1),鼠李素3OβD芸香糖苷(2),芦丁(3),阿福豆苷(4),桦木苷(5)和3,7dimethyloct1en3,8diol8OβDglucopyranoside(6)。结论所有化合物均为首次从该种植物中分离纯化得到。
Objective To study the chemical composition of Ligularia ulmoides. Methods A variety of chromatographic methods and chromatographic materials were used for extraction, separation, and purification. Structures were resolved using various modern spectroscopic methods. RESULTS Four flavonol glycosides and two monoterpene glycosides were isolated and purified from the ethanol extract of Ligularia virgaureum. They were methyl-rhamesin 3OβD rutinoside (1), rhamnosine 3OβD rutoside (2), reed D (3), aflavin (4), birchinoside (5) and 3,7dimethyloct1en3,8diol8OβDglucopyranoside (6). Conclusion All compounds were isolated and purified from the plant for the first time.
