摘要

目的：优选续断的水回流提取工艺。方法：以川续断皂苷Ⅵ转移率为评价指标，采用L9（34）正交试验考察液料比、提取时间、提取次数对续断提取工艺的影响。利用HPLC测定川续断皂苷Ⅵ含量，流动相乙腈-水（30：70），检测波长212 nm。结果：最佳提取工艺为加15，10倍量提取2次，每次2 h；平均转移率（94.83±0.31）%。结论：该工艺简单、稳定、提取率高，适用于工业化大生产。

Abstract

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.
