摘　　要：目的:优选干姜Zingiber Offcinale Rosc.中姜辣素的提取工艺。方法:采用回流提取和超声提取干姜中的姜辣素,采用紫外分光光度法测定姜辣素含量,并以辣椒碱的含量为指标,采用正交试验考察乙醇浓度、料液比、提取时间及提取次数对提取工艺的影响,确定最佳提取工艺。结果:相比超声提取,回流提取姜辣素含量更高。且回流提取最佳提取工艺:10倍量体积分数80%乙醇回流提取3次,每次1 h。结论:优选的提取工艺提取率高、稳定性好,可为干姜的工业化生产工艺提供指导。Objective： To optimize a extraction method of extracting gingerols from Ganjiang（ Dried Ginger）. Methods： Taken the gingerols content as index,orthogonal test was applied to investigate the influence of four factors（ including ethanol concentration,ratio of material-liquid,extraction time and extraction times） on extraction progress,and determined the optimal extraction method. Results： The optimum technical condition was as following： adding 10 times amount of 80% ethanol and reflux extract 3 times,1 hour each time. Conclusion： The extraction rate of this optimized extraction technology is high and stable,which can provide guidance for the industrialized production technology of dried ginger.
