| 摘 要： | 目的优选超声波辅助提取虎杖中白藜芦醇的最佳工艺。方法通过L16（4^5）正交实验研究5个因素不同水平对虎杖中白藜芦醇提取率的影响，采用紫外-可见分光光度法进行检测。结果经过正交实验得到从虎杖中提取白藜芦醇的最佳工艺为：以80％的CH3CH2OH＋CH3COCH3（体积比1：1）为提取剂，料液比1：10，pH=6，在30℃超声辅助提取50min，重复提取两次，虎杖中提取白藜芦醇的提取率可以达到1．83％。结论该实验确定的最佳提取工艺稳定性好且简便易行，且白藜芦醇的提取率高于有关报道。

| Abstract: | Aim To optimize the ultrasonic wave aided-extraction technology of resveratrol from Polygonum Cuspidatum. Methods The extraction methods were optimized by L 16 （4^5 ） orthogonal experiment. The extraction rate of resveratrol was determined by UV-spectrophotometer. Results Orthogonal experiment indicated that the optimum extraction condition of resveratrol were： 80% ethanol-acetone（1 ： 1） as extracting solvent, pH=6, the ratio of the solide material to the solvent is 1 ： 10, at 30 ℃ for extracting 50 min, the extraction can be done twice, the extraction rate is 1.83%. Conclusion The optimum extraction process is stable and easy, the yield of resveratrol from Polygonurn Cuspidatum is higher than some other published results. |
