目的研究猫须草[Clerodendranthus spicatus(Thunb.)C.Y.Wu]中的酚酸类化学成分。方法采用大孔树脂柱色谱、凝胶柱色谱及高效液相色谱等方法进行分离纯化,根据理化性质及波谱数据对化合物的结构进行鉴定。结果从猫须草水提取物中得到1个具有新颖桥环[2.2.2]的酚酸类化合物1。结论化合物1为新化合物,命名为猫须草酸E。
Aim To study the phenolic acids in Clerodendranthus spicatus (Thunb.) C.Y.Wu. Methods The compounds were isolated and purified by macroporous resin column chromatography, gel column chromatography and high performance liquid chromatography (HPLC). The structures of the compounds were identified according to the physicochemical properties and spectral data. As a result, one phenolic compound 1 having a novel bridged ring [2.2.2] was obtained from the aqueous extract of catfishes. Conclusion Compound 1 is a new compound, named cat oxalate E.
