A novel one-pot method based on deep eutectic solvent (DES) was developed to efficiently extract and convert polydatin to resveratrol from Polygonum cuspidatum. The extraction yield of resveratrol using DES was significantly higher than traditional solvents. The DES disrupted plant cell walls to enhance resveratrol yield.
The acquisition of resveratrol from Polygonum cuspidatum is complicated and costs organic solvents due to extraction and hydrolysis of its corresponding glycoside (polydatin). In this work, a novel one-pot method based on deep eutectic solvent (DES) was developed for simultaneous extraction and conversion of polydatin to resveratrol from Polygonum cuspidatum for the first time. The extraction yield of resveratrol by DES-based one-pot method were significantly higher than that of water, methanol and ethanol. After optimization by One-Variable at-a-Time and response surface methodology, the extraction yield of resveratrol reached 12.26 +/- 0.14 mg/g within 80 min. The conversation efficiency of polydatin to resveratrol in Polygonum cuspidatum from five different origins was more than 96.3%. Scanning electron microscope results indicated the selected DES disrupted plant cell walls to enhance the yield of resveratrol. The results indicated that one green method was successfully established for efficient extraction and conversion of polydatin to resveratrol from Polygonum cuspidatum.
