摘要:

通过实验建立了高速逆流色谱(HSCCC)结合硅胶柱色谱法分离制备干姜中6姜酚、8姜酚和6姜烯酚的方法。干姜样品采用乙酸乙酯超声提取,提取物经过硅胶柱色谱粗分,选取其中A3和A4两个馏分进行高速逆流色谱分离,所得单一成分采用高效液相色谱(HPLC)检测纯度,并采用电喷雾质谱(ESI-MS)、核磁共振氢谱(1H NMR)对所得化合物的结构进行鉴定。研究结果表明,该方法简便快捷,所得产物纯度高、制备量大、分离效率好。

Abstract:

We constructed the method of isolating 6gingerol, 8gingerol and 6shogaol from dry rhizome of Zingiber officinale Rosc. by silica gel column chromatography and highspeed countercurrent chromatagraphy based on experiments. We extracted the samples of Zingiber officinale Rosc. by ethyl acetate ultrasonic extraction and then coarsely treated them by silica gel column chromatography. We further selected fraction A3 and A4 to be separated by highspeed countercurrent chromatography(HSCCC). The purity of the obtained single ingredient was detected by highperformance liquid chromatography(HPLC) and the structure of the obtained compound was identified by electrospray ionization(ESIMS) and 1HNMR. Results show that the method has such positives as simplicity, rapidity, highpurity products, large amount of preparation and highefficiency separation.

Key words: Zingiber officinale Rosc., highspeed countercurrent chromatagraphy, silica gel column, 6-gingerol, 8-gingerol, 6-shogaol
