title: [Study on optimum extraction conditions of alkaloids from Pinellia ternate].
abstract: 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%.
