摘 要:目的研究漆姑草中的酚性化学成分。方法采用硅胶柱色谱、Sephadex LH-20凝胶色谱及RPC-18柱色谱进行分离纯化,并运用波谱方法对所分得化合物进行结构鉴定。结果从漆姑草中分得9个酚性化合物,经波谱解析分别确定为:E-对甲氧基肉桂酸甲酯(Ⅰ)、伞形花内酯(Ⅱ)、7-甲氧基香豆素(Ⅲ)、5,7-二羟基香豆素(Ⅳ)、5,7-二甲氧基香豆素(Ⅴ)、7-O-β-D-葡萄吡喃糖-6-C-β-D-木糖吡喃糖-5,4′-二羟基黄酮(Ⅵ)、5,7,2′-三羟基-8-甲氧基黄酮(Ⅶ)、5,7-二羟基-8,2′-二甲氧基黄酮(Ⅷ)、5,7,3′,4′-四羟基-6-甲氧基黄酮(Ⅸ)。结论所有化合物均为首次从该植物中分得。Objective To study the phenolic compounds from Sagina japonica. Methods The separation and purification were carried out by silica gel Sephadex LH-20 gel and RP C-18 colomn chromatography. The structures were identified by spectra. Results Nine phenolic compounds were isolated from S. japonica. They were identified as: p-E-methoxy cinnamic acid methyl ester (Ⅰ ), umbelliferone (Ⅱ), 7-methoxy coumarin (Ⅲ), 5, 7-di-hydroxy coumarin (Ⅳ), 5, 7-di-methoxy coumarin (Ⅴ), cerarvensim7-O-glucoside (Ⅵ), 5, 7, 2′-trihydroxy-8-methoxy flavone (Ⅶ), 5, 7-di- hydroxy-8, 2'-di-methoxy flavone (Ⅷ), 5, 7, 3', 4'-tetrahydroxy-6-methoxy flavone (Ⅸ). Conclusion All of these compounds are first isolated from S. japonica.
