Chemical constituents from Elsholtzia blanda
【摘要】 目的:研究四方蒿的化学成分。方法:硅胶、聚酰胺柱色谱进行分离纯化,通过理化性质和波谱数据鉴定结构。结果:分离得到5个黄酮类化合物,分别鉴定为木犀草素(Ⅰ),木犀草素-7-O-β-D-葡萄糖苷(Ⅱ),木犀草素-5-O-β-D-葡萄糖苷(Ⅲ),5-羟基-7,8-二甲氧基黄酮(Ⅳ)和5-羟基-6,7-二甲氧基黄酮(Ⅴ)。结论:化合物Ⅲ~Ⅴ为首次从该植物中分得,Ⅰ为首次从该属植物中分得。
【Abstract】 Objective: To investigate the constituents of Elsholtzia blanda.Method: The chemical components were isolated by polyamide and silica gel column chromatography.Their structures were identified with extensive spectral(EI-MS,ESI-MS,()1H-NMR,()13C-NMR,DEPT,()1H-()1H-COSY,HMBC,HMQC) and chemical methods.Result: Five compounds were isolated and identified as luteolin(Ⅰ),luteolin-5-O-β-D-glucopyranoside(Ⅱ),luteolin-7-O-β-D-glucopyranoside(Ⅲ),5-hydroxy-7,8-dimethoxyflavone(Ⅳ) and 5-hydroxy-6,7-dimethoxyflavone(Ⅴ).Conclusion: Compounds Ⅲ,Ⅳ,Ⅴ were isolated from E.blanda for the first time and Ⅰwas firstly separated from the genus Elsholtzia.
