| Abstract: | Objective： To optimize the ultrasound extraction process of the total saponins from Asparagus officinalis L. Methods： With the perchloric acid as a chromogenic agent, Using UV spectrophotometry method to determine the content of the total saponins in Asparagus officinalis L. and with the extraction rate as the evaluation index, using single factor experiment and orthogonal test to optimize the extraction process. Results： The optimum ultrasound extraction process of the total saponins from Asparagus officinalls L. was 70% ethanol, solid -liquid ratio 1：15 （W/V）, ultrasonic time 50 min, ultrasonic temperature 40 ℃. Conclusion： The extraction process is feasible to provide a basis for the further study on the total saponins in Asparagus officinalis L. |
