探讨云木香总生物碱最佳提取纯化工艺的影响因素,确定其最佳提取方案,为进一步分离提纯以及生产开发奠定基础。采用正交设计安排试验,以总生物碱含量作为评价指标,考察乙醇浓度、固液比、超声时间、提取次数对其影响。最佳工艺条件为14倍量的70%乙醇超声提取两次,每次75min,该结果在验证实验中得到验证。在研究得出的最佳提取工艺条件下提取云木香总生物碱简便、稳定、可行。
To explore the optimum extraction and purification technology of total alkaloids in A. farreri, and to determine the optimum extraction scheme, which will lay the foundation for further purification and production. Orthogonal design was used to arrange the experiment, and the total alkaloid content was used as the evaluation index to examine the influence of ethanol concentration, solid-liquid ratio, ultrasonic time and extraction times. The optimum conditions were 14 times the amount of 70% ethanol ultrasonic extraction twice, each 75min, the results in the verification experiment was verified. In the study of the best extraction conditions under the extraction of total alkaloids Yunxiang simple, stable and feasible.
