Objective:To optimize extraction technology of total saponins from Actinidia arguta roots and provide a reference for development of this medicinal part. Method: With extraction time
ethanol concentration and ratio of solid to liquid as independent variables
extracting amount of total saponins as dependent variable
extraction technology of total saponins from Actinidia arguta roots was optimized by central composite design-response surface methodology.UV was employed to determine the content of total saponins with detection wavelength at 547 nm. Result: Optimum technological parameters were as follows:extraction time of 73 min
ethanol concentration of 65%
solid-liquid of 1: 13;extracting amount of total saponins was 1.67 mg · g-1
which was coincided with the model predictive value of 1.69 mg · g-1. Conclusion: This optimized extraction technology is simple
reliable and suitable for extracting total saponins from A. arguta roots.
