title: [Study on the technique of ultrasonic wave extraction of triterpeneclucoside].
abstract: The extraction technique of ultrasonic wave on increasing the triterpeneclucoside was studied. Based on single factor experiments and the orthogonal design introduced,the optimized extracting conditions of triterpeneclucoside were investigated. The results showed that the best extraction technique conditons are 65% alcohol-water, the ratio of solid to liquid 1:30,dousing over 30 minutes,ultrasonic wave lasting for 40 minutes, ultrasonic frequency 26.8 KHZ, ultrasonic (output) power 1080 kw and extraction temperature 40 degrees C, respectively.
