摘要
本文采用正交试验,研究了从半夏中提取生物碱的工艺。研究结果表明:采用溶剂法提取半夏生物碱时,最佳的提取条件为:材料粉碎至60目,以2.575 mol/L的氨水搅拌均匀材料,加18倍的氯仿,于室温下浸提25h;半夏生物碱最高提取率为0.0817％。
The optimum extraction conditions of alkaloids from Pinellia ternate (Thunb. ) Breit were studied by orthogonal test. The results showed that the highest extraction rate of the alkaloids could be obtained by smashing the material in 60 (sieve number )of fragmentation and socking the material in 2. 575 mol/L ammonia water,extracting alkaloids with 18 times as much chlorolform at room temperature for 25 hours. The highest extraction rate of alkaloids was 0. 0817%.
