High-performance liquid chromatographic separation is performed to extract active components from the traditional Chinese medicine Polygonum cuspidatum using a trans-resveratrol imprinted polymer. Good separation and purification of trans-resveratrol and emodin from the Polygonum cuspidatum extract are achieved after condition optimization. The extraction recoveries are 83% and 99% for trans-resveratol and emodin, respectively. The results show that the molecularly imprinted polymer can be used as a selective extraction material for the extraction and purification of trans-resveratrol and emodin from Polygonum cuspidatum.
采用反式白藜芦醇印迹聚合物，通过高效液相色谱分离法从中药虎杖中提取活性成分。经条件优化后，实现了从虎杖提取物中对白藜芦醇和大黄素的良好分离与纯化。反式白藜芦醇和大黄素的提取回收率分别为83%和99%。结果表明，分子印迹聚合物可作为从虎杖中提取和纯化反式白藜芦醇和大黄素的选择性萃取材料。
