摘要: 目的:建立一种从高良姜粗提物中分离制备高纯度高良姜素的方法。方法:试验了逆流色谱(CCC)直接法以及逆流色谱(CCC)与硅胶柱色谱相结合两种方法从高良姜粗提物中分离制备高良姜素的方法。结果:先用硅胶柱色谱先对粗提物进行预分离,然后采用逆流色谱,以石油醚:乙酸乙酯:乙醇:水(2:0.4:0.8:0.9,v/v)为两相溶剂体系,对目标组分进行纯化,可以从高良姜粗提物中制备得到高纯度高良姜素。通过该方法可以从3.5g高良姜粗提物中分离得到纯度为99.1%的高良姜素15.6mg,纯度为95.2%的未知化合物Ⅱ5.2mg。结论:硅胶柱色谱与逆流色谱相结合为一种分离制备高纯度高良姜素有效方法。该方法可用于相关标准样品的研制及功能因子的开发。

Abstract: Purpose: To establish a method for the separation and preparation of galangin from Alpinia officinarum Hance. Methods: Two methods were developed for the preparative separation of galangin from Alpinia officinarum Hance, counter-current chromatography (CCC) directly and counter-current chromatography (CCC) combined with silica gel column chromatography. Results: The crude extract was pre-separated by silica gel chromatography, then separated by CCC with a two-phase solvent system composed of petroleum ether-ethyl acetate-ethanol-water (2:0.4:0.8:0.9, v/v) and high purity of galangin was obtained. 15.6mg galangin with the purity of 99.1% and 5.2mg unknown compound Ⅱ with the purity of 95.2% were obtained. Conclusions: The result indicates that silica gel chromatography combined with counter-current chromatography(CCC) can separate and preparate high purity of galangin from Alpinia officinarum Hance. This method has practical value and provides theoretical foundation for the further development.The method can be used for the preparation of the relevant standard materials and the development of functional factors.
