目的研究中药火绒草正丁醇层的化学成分。方法采用反复硅胶柱色谱法、Sephadex LH-20柱色谱法和反复重结晶等进行分离纯化,并通过波谱分析技术鉴定其化学结构。结果从火绒草中分离得到5个化合物,分别鉴定为:木犀草素-3′-O-β-D-葡萄糖苷(luteolin-3′-O-β-D-glucoside,1)、山奈酚-3-O-β-D-葡萄糖苷(kaempferol-3-O-β-D-glucoside,2)、金圣草素-4′-O-β-D-葡萄糖苷(chrysoeri-ol-4′-O-β-D-glucoside,3)、甘草苷(liquiritin,4)、腺苷(adenosine,5)。结论化合物2~5为首次从火绒草属植物中分离得到,化合物1为首次从火绒草中分离得到。
Objective To study the chemical constituents of n-butanol layer Methods The compounds were isolated and purified by repeated silica gel column chromatography, Sephadex LH-20 column chromatography and repeated recrystallization. Their chemical structures were identified by spectral analysis. Results Five compounds were isolated and identified as luteolin-3’-O-β-D-glucoside (1), kaempferol- 3-O-β-D-glucoside (2), chrysoeri-ol-4’- O-β-D-glucoside, 3), liquiritin (4) and adenosine (5). Conclusion Compounds 2 ~ 5 were isolated from Flammulina for the first time, and compound 1 was isolated from Flammulina for the first time.
