利用大孔树脂、MCI、ODS和Sephadex LH-20柱色谱以及反相制备液相色谱对川西千里光Senecio solidagineus Hand.-Mazz.正丁醇萃取部位的化学成分进行系统分离,并利用1H NMR、13C NMR等现代波谱技术鉴定其结构。结果从川西千里光中分离得到8个化合物,分别鉴定为丁香酚-O-β-D-吡喃葡萄糖苷(1)、灯盏花苷Ⅱ(2)、(6R,7E,9R)-9-hydroxymegastigma-4,7-dien-3-one-9-O-β-D-glucopyranoside(3)、crotonine(4)、bidensmethoside B(5)、松脂醇葡萄糖苷(6)、picraquassioside C(7)和3,3’-二甲氧基鞣花酸(8)。化合物2~8均为首次从该属植物中分离得到,化合物1为首次从该植物中分离得到。
The chemical constituents of n-butanol extraction were isolated by using macroporous resin, MCI, ODS and Sephadex LH-20 column chromatography and reversed-phase preparative liquid chromatography. The chemical constituents of n-butanol extraction were separated by 1H NMR, 13C NMR and other modern spectroscopic techniques to identify its structure. Results Eight compounds were isolated from Tricholoma giganteum and identified as eugenol-O- β -D-glucopyranoside (1), erigeron Ⅱ (2), (6R, 7E, 9R) -9- hydroxymegastigma-4,7-dien-3-one-9-O-β-D-glucopyranoside, crotonine, bidensmethoside B, 3,3’-Dimethoxylatelane (8). Compounds 2 ~ 8 were isolated from this genus for the first time, and compound 1 was isolated from this plant for the first time.
