title: Selective on-line extraction of trans-resveratrol and emodin from Polygonum cuspidatum using molecularly imprinted polymer.
abstract: 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.
