摘要
The bioactive compound 20-Hydroxyecdysone was successfully isolated and purified from Radix Serratulae Chinensis by high-speed counter-current chromatography with a solvent system of ethyl acetate-n-butanol-water (4:1:5, v/v/v) in one step. From 230mg of the n-butanol extract of Radix Serratulae Chinensis, 16.7mg of 20-Hydroxyecdysone was obtained with purity of 99.3%, as determined by high performance liquid Chromatography (HPLC). The structure was identified by mass spectrophotometry (MS), ultraviolet spectrophotometry (UV), and nuclear magnetic resonance spectrophotometry (NMR) analysis. In this study, a rapid method for isolation and purification of the major compound from Radix Serratulae Chinensis extract was established.
