提取了虎杖中的活性成分白藜芦醇,用高效液相色谱法检测白藜芦醇的含量。通过对5种不同提取工艺的比较,用正交设计选取最佳工艺,实验结果表明:弱碱性条件下超声波法提取效果最好,用10倍量pH=8的80%乙醇、超声波提取4次,每次15m in,白藜芦醇提取含量可达到0.373%。

Resveratrol was extracted and determined from Polygonum cuspidatum Sieb. et Zucc, and five different extraction process was compared and the orthogonal design obtained the optimal condition. Result showed that ultrasonic extraction at weak alkaline medium was the best extraction, with ten times amount of 80% EtOH （ pH 8 ）, extraction of 4 times, each 15 minu...
