摘要
目的:筛选虎杖中白藜芦醇的最佳提取工艺。方法:采用超声波提取,正交实验优化提取条件,高效液相色谱法测定虎杖中白藜芦醇的含量。结果:虎杖中白藜芦醇的提取最佳工艺为:液料比6:1,温度70℃,乙醇浓度70%,提取时间20min;各因素的影响依次为:提取液料比、温度、乙醇浓度、提取时间。结论:最佳优选结果经验证实验,具有较好的重现性。
Objective：obtain the best extraction processing of resveratrol from Polygotnum cuspidatum. Methods： supersonic extraction was used to extract, optimum extracting process was selected by the orthogonal test, the contents of resveratrol in Polygotnum cuspidatum were determined by HPLC. Results：the optimum condition of supersonic extraction was as follows： proportion of extracting solvents was 1：6, extracting temperature was 70℃, the concentration of ethanol was 70%, extracting time was 20min. The processing conditions affected the yield, and that the effect of each condition decreased in the following order： in proportion of extracting solvents, extracting temperature, the concentration of ethanol and extracting time. Conclusion： the best optimization outcome has a good repeatability after using in the test experiment.
