Abstract:

In order to improve comprehensive utilization of peanut and develop new materials for resveratrol, microwaveassisted extraction technology was applied to extract resveratrol from peanut root. Effect of factor such as microwave power, microwave treatment time, extraction temperature, ethanol concentration or solid-liquid rate on extraction rate of resveratrol was investigated. The extraction condition was optimized through orthogonal experiments. Results indicated that solid-liquid ratio exhibited the largest effect on extraction rate of resveratrol and ethanol concentration revealed the smallest effect. The optimal extraction condition was 400 W of microwave output power, 4.5 min of microwave treatment time, 80 ℃ of extraction temperature, 60% ethanol and 1:14 (g/ml) of solid-liquid ratio. The extraction rate of resveratrol from peanut root was 0.367% under this optimal condition.

Key words: resveratrol, peanut root, microwave-assisted extraction
