Objective: To optimize extraction technology of total saponins from Vaccariae Semen. Method: With dry powder yield and the mass fraction of total saponins as comprehensive evaluation index
orthogonal tests were adopted to optimize ultrasonic and ethanol reflux extraction processes by taking extraction time
solid-liquid ratio and ultrasonic power
ethanol concentration and extraction times as factors. Result: Optimum ultrasonic extraction conditions were as follows:extracted twice with 15 times the amount of 70% ethanol under 640 W
20 minutes per time;Dry powder yield and the mass fraction of total saponins were 7.34% and 10.92%
respectively.Optimum ethanol reflux extraction technology was as following:extracted twice with 14 times the amount of 60% ethanol under micro-boiling state
2 h per time;Dry powder yield and the mass fraction of total saponins were 7.17% and 9.01%
respectively. Conclusion: Ultrasonic assisted extraction method was better than ethanol reflux extraction method for total saponins from Vaccariae Semen
