Objective: To optimize water-extraction process of asperosaponin Ⅵ from Dipsaci Radix. Method: With transfer rate of asperosaponin Ⅵ as index
orthogonal design was used to optimize extraction process by taking liquid-solid ratio
extracting time and times as factors.The content of asperosaponin Ⅵ was determined by HPLC
mobile phase was acetonitrile-water(30:70) and detection wavelength set at 212 nm. Result: Optimum process conditions were as follows:extracted twice with 15
10 times the amount of water
2 h for per time.Under these conditions
transfer rate of asperosaponin VI was (94.83±0.309)%. Conclusion: This optimized process was simple
stable and productive
which was suitable for industrial production of Dipsaci Radix.
