Evidence Details
Under the optimal conditions, this approach achieved the highest yield of diosgenin (29.97 ± 0.51 mg) with 0.3 g steroid saponins. Compared with regular hydrochloric acid hydrolysis, the developed approach obtained 96% diosgenin and reduced 93% reaction time.
In summary, the optimal production conditions for diosgenin are provided as follows: 4 mol L−1 [BHSO3MIm]HSO4, the ratio of solvent to solid of 15:1, the reaction temperature at 100 °C, and reaction time of 20 min.
XH-800B intelligent microwave workstation with an output power of 0-1000 W was purchased from Beijing Xianghu Science and Technology Development Co., Ltd. (Beijing).
As shown in Table 1, [BHSO3MIm]HSO4 ionic liquid was stable and effective and the yield was decreased by 15% after five cycles.
