摘　　要：以穿龙薯蓣为实验材料,首先将纤维素、淀粉和皂苷复合物分离,然后对皂苷复合物酸水解获取皂素。结果表明,在1 mol.L-1硫酸溶液酸水解150 min、水解物中和水洗至近中性、20 min.次-1的回流速率下提取4 h的条件下,可获得最佳皂素提取率0.837%、纤维提取率13.86%、淀粉提取率12.34%。本工艺酸用量减少了80%、废水量减少了75%,废水COD值只有传统工艺废水的56%,大幅降低了污染程度,为实现穿龙薯蓣的资源化利用和皂素的清洁化生产提供技术支持。Using Dioscorea nipponica Makino as material, fiber, starch and saponin complex was separated, and then saponin complex was hydrolyzed by acid to obtain saponin. The results showed the optimal technology for saponin extraction was as follows：hydrolyzing for 150 min by 1 mol·L^-1 H2SO4, water scrubbing the pH value of hydrolyte to nearly neutral and refluxing for 4 h with a speed of 25 min for every operation. Under such conditions, saponin extraction rate could reach 0. 837%, fiber extraction rate was 13.86%, starch extraction rate was 12.34%. Compared with those of traditional craft,the acid consumption reduced 80% ,the generated wastewater quantity decreased 75% ,even the COD value of the wastewater dropped 44%. In a word,the novel process led to a significant reduction in pollution, and it provided technical support to achieve resources exploitation of Dioscorea nipponica Makino and clean production of saponin.
