摘　　要：报道了微波强化薯蓣皂甙水解的研究。实验表明微波可以明显促进薯蓣皂甙的水解。与水浴加热方法相比,微波水解可减少HCl用量50%,缩短水解时间92%,提高得率20%。采用正交实验对微波辐照时间、微波功率、[H+]浓度3个影响微波催化薯蓣皂甙水解的因素进行了研究,探讨了微波催化水解的机理。实验结果表明,微波强化薯蓣皂甙水解的最优实验条件为:微波功率700W,C[H+]=2 mol/L,水解时间20 min。Hydrolysis of dioscin by microwave irradiation was reported, and the result showed that hydrolysis of dioscin was promoted obviously by microwave irradiation. Compared with water bath heating, usage of hydrogen chloride was decreased to 50%, hydrolytic time was shortened by 92%, and the yield was increased 20% by microwave hydrolysis. The effect of irradiation time, power and pH on the hydrolysis was studied, and the hydrolytie mechanism by mierowave heating was discussed. The optimal condition was chosen by orthogonal experiment as microwave power of 700 W, with pH 2 and irradiation for 20 min.
