TITLE:
摘要: 目的:研究黑面神药材70%乙醇提取部分的化学成分。方法:采用D101大孔树脂、硅胶柱色谱、反相硅胶柱色谱、Sephadex LH-20凝胶柱色谱、薄层色谱、制备型高效液相色谱对黑面神药材70%乙醇提取部位化合物进行分离纯化,根据理化性质和波谱数据分析鉴定化合物的结构。结果:从黑面神药材70%乙醇提取部分中分离得到10个化合物,分别鉴定为木犀草素(1)、槲皮素(2)、山柰酚(3)、银椴苷(4)、(+)-南烛木树脂酚(5)、(+)-异落叶松脂素(6)、(+)-Nortrachelogenin (7)、(+) -丁香树脂醇(8)、Icariol A2(9)、5,5′ -二甲氧基-7-氧代落叶松脂醇(10)。结论:10个化合物均为首次从该植物中分离得到。该研究为黑面神药材质量评价奠定了基础。
ABSTRACT: OBJECTIVE: To study the chemical constituents of 70% ethanol extract of Breynia fruticosa. METHODS: The 70% ethanol extract of B. fruticosa were isolated and purified by D101 macroporous resin, silica gel column chromatography, RP-silica gel column chromatography, Sephadex LH-20 gel column chromatography, preparative HPLC. The structure of compound was analyzed and identified according to physicochemical characters and spectral data. RESULTS: 10 compounds were separated from 70% ethanol extract of B. fruticosa, such as Luteolin (1),Quercetin (2),Kaempferol (3),Tiliroside (4),(+)-Lyoniresinol (5), (+)-Isolariciresinol (6),(+)-Nortrachelogenin (7),(+)-Syringaresinol (8),Icariol A2(9), 5,5′ -Dimethoxy-7-oxolariciresinol (10), respectively. CONCLUSIONS: Ten compounds are isolated from this plant for the first time. The study play the found for quality evaluation of 70% ethanol extract of B. fruticosa.
