摘　　要：从穿龙薯蓣Dioscorea nipponica中分离得到的一少根根霉原变种Rhizopus arrhizus var.arrhizus菌株,能实现薯蓣皂苷的生物转化。用该菌株发酵穿龙薯蓣D.nipponica生产薯蓣皂苷元,采用高效液相色谱法测定薯蓣皂苷元的含量,其总得率可达3.00%。运用该菌株发酵制备薯蓣皂苷元,操作简单,环保,且得率高。Biotransformation of dioscin into diosgenin could be performed by a Rhizopus arrhizus var. arrhizus strain isolated from Dioscorea nipponica. Diosgenin extraction through fermenting D. nipponica by the strain was carried out. HPLC measurement showed that biotransformed diosgenin was highly yielded, reaching 3.00%, while the extraction ratio was improved. This is a simple and environmentally beneficial method with high yield of diosgenin worthy to be popularized
