| titleOfInvention | Preparation method of 6-gingerol |
| abstract | The invention relates to a preparation method of 6-gingerol. The preparation method comprises the following steps: (1) pretreatment: adding an ethanol solution into ginger resin, dissolving, and then adding water to adjust the volume fraction of ethanol to be 50-60% while homogenizing to obtain a ginger resin ethanol mixed solution; (2) cooling and impurity removal: cooling the ginger resin ethanol mixed solution in the step (1) until a precipitate is separated out, heating to room temperature, and separating and removing the oily matter after the precipitate is melted into the oily matter to obtain an ethanol solution phase; (3) liquid-liquid extraction: adjusting the volume fraction of ethanol in the ethanol solution phase in the step (2) to 70-90%, performing liquid-liquid extraction by adopting n-hexane, collecting the ethanol phase, concentrating, and removing water to obtain a crude product of 6-gingerol. The 6-gingerol in the 6-gingerol crude product prepared by the preparation method has high content, is beneficial to purifying and obtaining high-purity 6-gingerol, improves the yield of 6-gingerol, and reduces the preparation cost. |
