摘　　要：采用正交实验法对广西萝芙木总生物碱进行了提取工艺的优化。实验结果表明,广西萝芙木总生物碱最佳提取工艺为:提取时间90 min,提取温度45℃,提取溶液p H值=3。在此条件下,萝芙木浸膏得率为12.13%,总生物碱的提取率为1.23%。该工艺稳定可行,具有一定的现实意义,为广西萝芙木总生物碱的规模化生产提出了借鉴意义。The extraction process of vtotal alkaloids in Rauwolfiais from Guangxi was optimized by orthogonal experimental method. The results showed that the optimal extraction process of the total alkaloids obtained by the orthogonal test was as follows: the extraction time 90 min, the extraction temperature 45 ℃, and the extraction solution pH value 3. Under above condition, the yield of Rauwolfia vomitoria extract was 12.13%, and the yield of total alkaloids was 1.23%. This process is stable and feasible. It has certain practical significance and provides reference for the large-scale production of total alkaloids from Rauvolfia in Guangxi.
