摘要: | 目的:研究白花蛇舌草氯仿部位的化学成分。方法:采用硅胶柱色谱、Sephadex LH-20凝胶柱色谱和薄层色谱对白花蛇舌草氯仿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结构。结果:从白花蛇舌草氯仿部位中分离得到11个化合物,分别鉴定为2-羟基-3-甲基蒽醌(1)、2-羟基-1-甲氧基-3-甲基蒽醌(2)、2-羟基-1-甲氧基蒽醌(3)、邻苯二甲酸二丁酯(4)、甲基异茜草素(5)、熊果酸(6)、耳草酮B(7)、莨菪亭(8)、2,6-二羟基-3-甲基-4-甲氧基蒽醌(9)、2-羟基-3-羟甲基蒽醌(10)、正十六烷(11)。结论:化合物4、7、10、11为首次从白花蛇舌草植物中分离得到,本研究为白花蛇舌草质量评价奠定了一定基础。 |
ABSTRACT: | OBJECTIVE: To study the chemical constituents of the chloroform from Hedyotis diffusa. METHODS: Silica gel, Sephadex LH-20 column chromatography and preparative thin layer chromatography were conducted to classify and purify of chemical constituents of the chloroform from H. diffusa, the chemical structures were analyzed and identified based on physicochemical properties and spectral data. RESULTS: Totally 11 compounds were obtained from the chloroform of H. diffusa, namely 2-hydro- xy-3-methylanthraquinone (1), 2-hydroxy-1-methyl-3-methoxyanthraquinone (2), 2-hydroxy-1-methoxyanthraquinone (3), dibutyl phthalate (4), rubiadin(5), ursolic acid (6), hedyotiscone B (7), scopoletin (8), 2, 6-dihydroxy-3-methyl-4-methoxyanthraquinone (9), 2-hydroxy-3-hydroxymethylanthraquinone (10) and n-hexadecane (11). CONCLUSIONS: Compound 4, 7, 10, 11 are firstly obtained from H. diffusa, the study had laid certain foundation for the quality evaluation of H. diffusa. |
