摘要: [摘要]目的:对药用植物云南龙胆的化学成分进行研究。方法:采用AB-8型大孔树脂、硅胶、Sephadex LH-20、中压色谱分离
凝胶(MCI)和十八烷基硅烷键合硅胶(ODS)等多种柱色谱技术,对云南龙胆95%乙醇提取物进行分离,并采用现代波谱技术
对分离得到的化合物进行结构鉴定。结果:从云南龙胆中分离得到7个黄酮类化合物,分别鉴定为异荭草素(1)、牡荆素(2)、
芹菜素-7-O-β-D-吡喃葡萄糖苷(3)、木樨草素-7-O-β-D-吡喃葡萄糖苷(4)、柚皮素(5)、山柰酚(6)和葛根素(7)。结论:
7个化合物均首次从该药用植物中分离得到,其中化合物4为首次从该属植物中分离得到。

Abstract: 〔Abstract〕Objective: To study the chemical constituents of medicinal plant Gentiana yunnanensis. Methods: The chemical
compounds were isolated from the 95% ethanol extract of G. yunnanensis by the techniques of column chromatography including AB-8
macroporous adsorptive resins, silica gel, Sephadex LH-20, middle chromatogram isolated gel(MCI)and octadecylsilane chemically
bonded silica(ODS), and the structures of the compounds were identified based on modern spectroscopic techniques. Results: Seven
flavonoids were isolated from G. yunnanensis and identified as isoorientin(1), vitexin(2), apigenin-7-O-β-D-glucopyranoside(3),
luteolin-7-O-β-D-glucopyranoside(4), naringenin(5), kaempferol(6)and puerarin(7). Conclusion: Seven compounds were all
isolated from this plant for the first time, among which compound 4 was isolated from this genus for the first time.
