目的系统研究甘肃棘豆的化学成分。方法利用普通硅胶柱色谱对甘肃棘豆乙醇提取物进行化学成分分离,并运用超导核磁(NMR)及高分辨质谱(HR-ESI-MS)等现代波谱技术,结合文献资料的已知化合物波谱数据对分离得到的化合物进行结构鉴定。结果从甘肃棘豆分离并鉴定了13个化合物,分别为鼠李柠檬素(1)、鼠李柠檬素-3-O-β-D-半乳糖苷(2)、鼠李柠檬素-3-O-β-D-半乳糖-4′-O-β-D-葡萄糖苷(3)、(±)-10-甲氧基美迪紫檀素(4)、7β-羟基-β-谷甾醇(5)、7α-羟基-β-谷甾醇(6)、5,11-豆甾二烯-3-醇(7)、β-谷甾醇(8)、β-胡萝卜苷(9)、大豆皂醇B(10)、大豆皂苷Ⅰ(11)、大豆皂苷Ⅱ(12)、DL-3-O-甲基-肌醇(13)。结论以上化合物均为首次从该植物中分离得到。
Objective To systematically study the chemical constituents of Oxytropis gansuensis. Methods The constituents of ethanolic extracts from Oxya chinensis were separated by general silica gel column chromatography and analyzed by modern spectroscopic techniques such as superconducting nuclear magnetic resonance (NMR) and high-resolution mass spectrometry (HR-ESI-MS). Combined with the known compound spectra Data were isolated from the structure of the compounds identified. Results Thirteen compounds were isolated and identified from Oxytropis Gansu, and they were rhamnoides (1), rhamnosyl-3-O-β-D-galactoside O-β-D-galactose-4’-O-β-D-glucoside (3), (±) -10- methoxypyridaetillate (4), 7β-hydroxy-β-sitosterol 5, 7α-hydroxy-β-sitosterol (6), 5,11-stigathiadien-3-ol (7), β-sitosterol (8), β- B (10), soyasaponin I (11), soyasaponin II (12) and DL-3-O-methyl-inositol (13). Conclusion The above compounds were isolated from this plant for the first time.
