Abstract: This study was to investigate the extraction method of the vacuum heat reflux extraction of peanut budresveratrol，and the optimum conditions were determined by orthogonal test. The thermal reflux time was 100min；theparticle size of the material was 40；the ratio of solid to liquid was 1∶14；the ethanol concentration was 95%；and theextraction rate was 4.282mg/kg. In the end，the better development conditions for the determination of resveratrol inthin layer chromatography（5∶4∶1）were explored.

Key words: heat reflux extraction；extraction；thin-layer chromatography
