Extraction technology of grape seed procyanidins from rapeseed meal by microwave method were studied in this article. The effect of solvent type, solvent concentration, extraction time, extraction of the solid-liquid ratio, extraction temperature on rate of extraction of procyani- dins and the best extraction process by response surface analysis were explored. The results show that: 70% ethanol as extraction solvent, solid-liquid ratio of 1 : 7. 5, plus 0. 1% citric acid assis- ted extraction, microwave extraction temperature of about 55℃, the extract total time 90 rain, procyanidin content of 7. 06%, the extraction rate (69. 54 -+ 3.46) %, better than the traditional water bath heating extrnetion method.
