目的:研究冬凌草(Rabdosia rubescens (Hemls.) Hara)地上部分的化学成分。方法:利用大孔吸附树脂色谱进行分离纯化,根据化合物的理化性质和光谱数据鉴定结构。结果:从冬凌草地上部分分离得到7个化合物,分别为:冬凌草碱(1),黄嘌呤(2),芹菜素-6,8-二-C-β-D-葡萄糖苷(3),7-羟基-4(1H)-喹啉酮(4),1,5-二-(3,4-二羟基苯基)-乙烯醚(5),3-(3,4-二羟基苯基)-2-异丙氧基-丙酸(6),邻苯二甲酸双-(2-乙基己基)酯(7)。结论:化合物1为新化合物,其余化合物均为首次从该属植物中分离得到。
Objective: To study the chemical components of the aerial parts of Rabdosia rubescens (Hemls.) Hara. METHODS: Separation and purification were carried out using macroporous adsorption resin chromatography. Structures were identified based on the physicochemical properties and spectral data of the compounds. RESULTS: Seven compounds were isolated from the upper part of Dongling grassland. They were: Rabdoxin (1), xanthine (2), apigenin-6, 8-di-C-β-D-glucoside (3 ), 7-Hydroxy-4(1H)-quinolinone (4), 1,5-bis-(3,4-dihydroxyphenyl)-vinylether (5), 3-(3,4-dihydroxyl) Phenyl)-2-isopropoxy-propionic acid (6), bis-(2-ethylhexyl) phthalate (7). Conclusion: Compound 1 is a new compound, and the other compounds were isolated from this genus for the first time.
