摘要
采用热分解处理后的黄姜作为原料,进行薯蓣皂素的提取研究。从原料粒度、萃取剂用量、提取温度、提取时间等方面进行了试验。结果表明,原料粒度为40目左右,萃取剂用量为150mL.10g-1原料,提取温度为85℃,时间为6h,萃取效果较好,皂素收率可达1.6%。与传统方法比较,二者萃取率相当,但热分解方法所用萃取剂量较大,但整个生产过程无废水,环保效益显著。
The extracting diosgenin from heat-decomposed Dioscorea Zingiberensis was studied in this paper. The effect of diameter of material powder, solvent amount, extracting temperature, extracting time on the extracting rate were discussed. The results showed that the optimum technological conditions had been attained as follows： the diameter of material powder about 40 mesh, the ratio of solid to liquid 10g·150mL^-1,extracting temperature 85℃,extracting time 6h,and its extracting rate was 1.6%. Compared with the traditional methods, the effects of extraction was similar, The amount of solvent was larger, but there was no waste water in the whole process, the environmental profits are of the first magnitude.
