Abstract: Effects of ethanol concenttration, temperature, material-solution ratio and extraction time on extraction rate of total flavonoids from ‘Enwuyemi’Gynostemma pentaphyllum were studied, and the extraction technology was optimized by orthogonal test L9(34). The results showed that the optimal extraction conditions are ethanol concenttration 70%, material-solution ratio 1:10, water bath temperature 90 ℃ and extraction time 1 h. Under the conditions, the extraction rate of total flavonoids is 4.1%.
