Abstract:

To optimize the extraction technology of resveratrol from peanut root, response surface methodology was applied on the basis of single factor tests. The results showed that ethanol concentration, temperature and extraction time significantly affect the resveratrol extraction, and after optimization, they are 65%, 52 ℃ and 39 min, respectively. Under these conditions, the resveratrol yield is 0.012%. In conclusion, the optimization of extraction technology of resveratrol from peanut foot by response surface methodology is feasible, and the extraction technology has practical application value.

Key words: resveratrol, peanut root, extraction, response surface methodology
