Abstract: This study was aimed to optimize the vacuumextraction technology of alkaloids fromSophora alopecuroides. The orthogonal test and comprehensive evaluation were used to optimize the vacuumextraction technology. Contents of total alkali and oxymatrinewere used as index components for optimizing the effect of three factors, which were the adding amount of water, extraction time, and extraction frequency. Comparison was made among optimal conventional extraction process, decoction extraction and vacuumextraction. The results showed that the optimum extraction process was to add 12 times amount of water, and to extract for 3 times under the temperature of 60℃, 1h for each time. It was concluded that the optimized extraction vacuum technologyof alkaloids fromS. alopecuroidsdecompression total alkali content and oxymatrine process was better than that of optimal conventional extraction process and decoction extraction. The vacuumextraction technology was stable and practical.
